  • low-noise and low-vibration operation of the air compressor which is often arranged in the passenger compartment of a vehicle, is desirable.
  • Piston compressors with connecting rods which have different characteristics, are known from the prior art. From the DE 103 23 125 A1 for example, a connecting rod for the piston of a compressor is known, which additionally has a vibration damping device which is arranged between the connecting rod bearing and a coupling point.
  • the WO 85/02232 discloses a piston compressor with at least two pistons and a rotary drive, the two pistons being axially aligned with one another and firmly connected to one another with a rigid piston rod.

  • the DE 19 46 149 A describes a compressor that delivers compressed air even when a single cylinder compressor is used for air intake cannot emit air. This is achieved in that a piston rod is arranged between two opposing cylinders. The air emerging from both outlet valves flows into a common hose line. When the pistons move from right to left, the air combined in the left cylinder is led through the outlet valve into the hose line. Air is drawn in from the right piston through the intake valve. This reciprocal way of working creates a constant air flow in the hose line.
  • the hose line is only arranged on one side next to the connecting rod, so that there is an asymmetrical mass distribution with respect to the vibration plane of the piston.
  • the check valves have a lower closing force and at the same time a high tightness.
  • a valve piston is arranged between a low-pressure piston with a low-pressure chamber and a high-pressure piston with a high-pressure chamber.
  • the low pressure chamber and the high pressure chamber are connected to each other via an overflow channel.
  • the overflow channel opens into at least two through holes.
  • the DE 103 23 125 A1 shows a connecting rod for the piston of a compressor, wherein at least one vibration damper device is arranged between the connecting rod bearing and the coupling point.
  • the connecting rod is axially offset from the vibration level behind the overflow channel and not in the vibration level of the connecting rod.
  • piston compressors with connecting rods for pistons of a compressor which have an air duct.
  • This usually runs in such a way that it overlaps the connecting rod in the transverse direction or is arranged in front of the connecting rod.
  • the air duct on the connecting rod runs such that the air duct can be arranged, for example, on the side on which the connecting rod can be connected to an eccentric shaft by means of a bearing, a drive device, such as an electric motor.
  • the air duct is arranged between the connecting rod and the drive device.
  • a connecting rod of this type is usually arranged in a compressor between the output of a drive device and a piston or piston carrier of the compressor in order to convert the rotating, eccentric output movement of the drive device into a reciprocating movement of the piston via the connecting rod.
  • the space in which the piston compressor or connecting rod can be placed is limited.
  • the object of the invention is to propose a piston compressor which requires only a small installation space and which experiences an optimized or reduced load due to forces or moments and which enables an air compressor to operate with low noise. Furthermore, it is an object of the invention to propose a piston compressor which is light in weight.
  • the invention relates to a piston compressor, in particular for a double-piston system, with a connecting rod for at least one translationally oscillating piston, the connecting rod with a portion being able to be supported by means of a first connecting rod bearing on an eccentric extension of an eccentric shaft of a drive device and being arranged in a connecting rod movement plane.
  • the connecting rod movement plane is defined as the mass balance plane of the connecting rod, which is perpendicular to the driving crankshaft.
  • At least one air duct be arranged next to the connecting rod and in one plane with the connecting rod so that the connecting rod does not overlap the connecting rod in at least one transverse direction lying in the plane.
  • the plane at least partially coincides with the connecting rod movement plane, and a center of gravity of the at least one translationally oscillating piston for which the connecting rod is designed runs in this connecting rod movement plane.
  • placing next to the connecting rod means arranging it at such a position that it is not in a space between the connecting rod and a drive device or a position opposite the connecting rod.
  • the at least one air duct is therefore preferably arranged in one plane with the connecting rod.
  • one plane means that the at least one air duct is arranged next to the connecting rod, starting from a direction of view of a side surface of the connecting rod.
  • a plane also means that the plane at least partially coincides with the connecting rod movement plane.
  • the connecting rod preferably moves within the connecting rod movement plane at least along a longitudinal direction, and preferably also along a transverse direction within the connecting rod movement plane.
  • This can be achieved by means of a drive device and an eccentric shaft connected to it as a crankshaft, an eccentric extension being connected to a first connecting rod bearing.
  • the eccentric shaft is usually aligned normal to the connecting rod movement plane.
  • the longitudinal direction and the transverse direction span the connecting rod movement plane.

  • a definition delimiting the known arrangements can thereby be achieved.
  • the connecting rod movement plane and the plane of the air duct are completely identical.
  • the at least one air duct is therefore arranged in the connecting rod movement plane.
  • the air duct preferably runs completely outside the connecting rod.
  • the air duct can consequently be arranged outside the connecting rod, but in the connecting rod movement plane.
  • the at least one air duct is arranged such that it does not overlap the connecting rod in at least one transverse direction of the plane.
  • the air duct runs in the connecting rod movement plane next to the connecting rod.
  • the air duct preferably runs over the entire length of the connecting rod.
  • the at least one air duct can be arranged at a distance from the connecting rod.
  • Such an arrangement of the air duct with respect to the connecting rod enables a space-saving design to be achieved. Furthermore, an optimized or reduced load can be achieved by forces or moments of the individual components, and low-noise operation of an air compressor with such a piston compressor can be made possible. The vibrations can also be reduced.
  • the piston compressor can additionally have a vibration damping device which is arranged between the connecting rod bearing and a coupling point.
  • a vibration damping device which is arranged between the connecting rod bearing and a coupling point.
  • This can be formed via a decoupling element, for example decoupling rings, by means of which shock forces are damped and a flexible and simple assembly of the connecting rod is ensured.
  • the coupling element consequently acts as a damper.
  • the course of the air duct can preferably be adapted at least in sections to the outer contour of the connecting rod and / or spaced apart from the outer contour be arranged.
  • the air duct can run at least in sections along a curve and / or along a line. It is also possible for the air duct to be arranged entirely within the connecting rod movement plane.
  • Such an arrangement of the at least one air duct with respect to the connecting rod makes it possible to form a slim piston compressor, by means of which installation space can be saved. This also has a positive effect on the compact design of a compressor.
  • the at least one air duct can be arranged within a connecting element that runs from below the connecting rod to above the connecting rod.
  • the connecting element can be designed, for example, as a hollow structure with an arbitrary cavity cross section and can be connected at one end to a first piston and at a second end to a second piston.
  • the at least one air duct can be arranged next to the connecting rod in such a way that it overlaps the connecting rod in a depth direction with respect to the plane.
  • the air duct can be arranged laterally next to the connecting rod so that it overlaps the connecting rod when looking at the depth or thickness of the connecting rod.
  • Such a viewing direction is consequently arranged within the plane of movement, wherein the viewing direction can correspond to the transverse direction of the plane.
  • overlapping means that the air duct is arranged in front of the connecting rod if the viewing direction is aligned with the depth or thickness of the connecting rod.
  • the air duct or its cross section can be adapted to the depth or thickness of the connecting rod so that it does not protrude beyond the thickness or depth of the connecting rod, so that space can still be optimally used.
  • a delimitation from the known arrangements of air ducts from the prior art can be achieved particularly advantageously.
  • the air duct runs, for example, on the connecting rod in such a way that the air duct is arranged on the side on which the connecting rod is connected to an eccentric shaft by means of a bearing, a drive device, such as an electric motor.
  • the air duct is between the connecting rod and the drive device arranged. This is not the case in the present embodiment.
  • less installation space is required and mass compensation is achieved in the connecting rod movement plane. In this respect, undesirable vibrations from the connecting rod movement plane can be prevented.
  • the air duct can have a cross section which is less than or equal to the smallest cross-sectional dimension of the connecting rod and / or the depth of the connecting rod, the air duct being arranged completely in the connecting rod movement plane.
  • a cross-sectional dimension of the connecting rod can be, for example, the thickness of the connecting rod. If the connecting rod has different thicknesses, the air duct can be designed, for example, with a diameter that corresponds to this thickness. If the air duct is arranged next to the connecting rod, the air duct and the connecting rod lie in one plane, the air duct covering or overlapping the connecting rod in the thickness direction at least in regions if the viewing direction is directed to the thickness or depth of the connecting rod.
  • the air duct can have a round cross section.
  • the air channel can have different diameters or a constant diameter over the length. The diameter can be adapted to the required volume flow.
  • the air duct can run at an angle along an outer contour of the connecting rod, the connecting rod preferably being arranged at a distance from the outer contour. If the course of the air duct is adapted to the outer geometry of the connecting rod, installation space can still be optimally used and saved.
  • the air duct is advantageously arranged at a distance from the outer contour of the connecting rod, so that it does not touch the connecting rod even during operation.
  • At least two air channels can be present.
  • a second air duct can have the same construction as the first air duct and lie in one plane with the first air duct and with the connecting rod, ie likewise within the connecting rod movement plane or plane.
  • the at least two air ducts are formed parallel to one another or also mirrored with respect to one another with respect to at least one axis.
  • the volume flow can be significantly increased and optimally adjusted.
  • a slim design of the piston compressor can also be achieved.
  • the second air duct can be arranged next to the connecting rod and in one plane with the connecting rod such that the connecting rod does not overlap the connecting rod at least in a transverse direction, the plane at least partially coinciding with the connecting rod movement plane, and a center of gravity line of the at least one translatory oscillating piston in the connecting rod movement plane. It is conceivable, for example, to have two air ducts arranged parallel to one another and directly adjacent on one side of the connecting rod, i. H. in the transverse direction next to the connecting rod, which have the same geometry.
  • the second air duct can be arranged such that it overlaps the connecting rod in at least one depth direction with respect to the plane. Overlapping means that the second air duct is arranged in front of the connecting rod, as seen from a direction of view of the thickness or depth of the connecting rod. Such a viewing direction is consequently arranged within the connecting rod movement plane, wherein the viewing direction can correspond to the transverse direction of the plane.
  • the second air duct preferably lies in one plane with the connecting rod.
  • the two air channels can each be connected to one opposite side with respect to the connecting rod, or also be arranged on the same side.
  • the two air channels can be formed symmetrically with respect to a longitudinal axis of the connecting rod, the longitudinal axis being in particular a center of gravity of the at least one translationally oscillating piston.
  • An air duct preferably runs to the right and another to the left of the connecting rod, viewed from a direction of view of a side surface of the connecting rod. Both air ducts are preferably arranged at a distance from the outer contour of the connecting rod, so that they do not touch the connecting rod. Both air ducts therefore preferably run outside the connecting rod.
  • the center of gravity of the at least one translationally oscillating piston can thus also form the center of gravity between the two air ducts, so that a symmetrical arrangement and thus a balance of forces is created. Consequently, the longitudinal axis of the connecting rod can coincide with the center of gravity of the at least one piston. Furthermore, if the center of gravity lies within the connecting rod movement plane, a particularly space-saving arrangement of the air channels and of the connecting rod with respect to the at least one piston, in particular between two pistons, can be achieved.
  • the two air ducts can open into a common duct.
  • the common channel is preferably above the connecting rod or below the connecting rod. In this way, both pistons can be reached, particularly in a double-piston system.
  • the common channel can be arranged in the center of gravity of the piston.
  • At least one balancing disk can be arranged at the level of the first connecting rod bearing.
  • the balancing disk is preferably arranged particularly close to the piston.
  • At least two balancing disks can be arranged at the level of the first connecting rod bearing.
  • the two balancing disks can have the same design.
  • the two balancing disks can be designed symmetrically to one another. It is also conceivable to have more than two balancing letters to be arranged, for example two balancing disks can each be arranged parallel to one another. By arranging two balancing letters, a tilting moment can be reduced. The resulting reduced inertia forces also reduce the dynamic effects, which means that the operation of the piston compressor can be optimized.
  • a first balancing disk can be arranged on one side of the connecting rod, which can be aligned in the direction of an eccentric shaft, and the second balancing disk on an opposite side of the connecting rod.
  • the two balancing disks can be arranged on two opposite sides of the connecting rod, wherein the first balancing disk can be arranged, for example, in front of the connecting rod, as seen from a direction of view of the side surface of the connecting rod, and the second balancing disk behind the connecting rod.
  • the two balancing disks can be formed symmetrically with respect to a longitudinal axis of the connecting rod. If the two balancing letters are symmetrical to each other, there is also a symmetrical weight distribution, which further reduces a tilting moment. Overall, forces and moments can be optimally compensated by two balancing letters, since the center of mass lies on the longitudinal axis.
  • At least one piston which is formed in one piece or in several parts, can be arranged above the connecting rod as a high-pressure piston, which is connected to the at least one air duct.
  • the at least one air duct can form the function of the connection between a first and a second compressor unit between a low-pressure and a high-pressure stage.
  • At least one piston which is designed in one piece or in several parts, can be arranged below the connecting rod as a low-pressure piston, which is connected to the at least one air duct.
  • the at least one air duct can also form the function of the connection between a first and a second compressor unit.
  • the low and high pressure stage is connected via the one or more air channels and a valve system that provides a controlled flow of compressed air from the low pressure to the high pressure stage.
  • the valves required for this can be arranged in the bottom of the respective pistons of the compressor stages and / or in the air duct or the air ducts.

  • the lower bearing 13, which supports a low-pressure piston 16a on the connecting rod 14, has one or more decoupling elements 40, by means of which impact forces can be damped and flexible and simple assembly of the connecting rod 14 is ensured.
  • the decoupling element 40 is used for a mechanically resilient decoupling to suppress the vibrations of the connecting rod 14 and the lower low-pressure piston 16a and can be designed, for example, as a rubber ring or similar resilient decoupling element, and consequently acts as a damper.
  • a high-pressure piston 16b is arranged above the connecting rod 14.
  • the connecting rod 14 is consequently arranged between the low-pressure piston 16a and the high-pressure piston 16b.
