Definitions
- the present invention relates to a linear compressor, in particular a linear compressor, which is suitable for compressing refrigerant in a refrigerator.
- a linear compressor having a pumping chamber in which a piston is reciprocable is fixed to a frame fixed to the pumping chamber, to which a vibrating body is reciprocated by at least one spring, one mounted to the frame Electromagnet for driving the reciprocating motion of the vibrating body and a piston rod known, which connects the vibrating body to the piston.
- the spring is a diaphragm spring, the edge of which is fastened to the annular space surrounding the pumping chamber and screwed to the center of the cup-shaped oscillating body and one end of the piston rod.
- the other end of the piston rod is spherical and engages a cup formed on the piston so that the piston rod and the piston are pivotally movable with respect to one another.
- the pivotal mobility prevents the transmission of torque from the vibrating body via the piston rod to the piston, which could cause the piston in the pumping chamber to tilt and become difficult to move.
- the piston In order to achieve sufficient security against tilting, the piston must have a considerable length. Accordingly, a lot of space for the piston is required in the pumping chamber, so that the ratio of pumping chamber volume to throughput is rather unfavorable.
- piston rod can also transmitted transversely to the direction of movement of the piston in the pumping chamber oriented forces on the piston, this against a
- the gas film formed along the side wall prevents direct contact between the pump chamber wall and the piston, if the gas flow rate is high enough.
- the object of the invention is to provide a linear compressor in which the transmission of lateral forces from the vibrating body is minimized to the piston.
- the object is achieved in that the connection of a jointed with the piston Mattertragerstange is formed with the oscillating body by a second joint.
- the Studentstange can thus essentially only tensile and shear forces transmitted to the piston, but no significant lateral forces.
- the two joints can be particularly simple and inexpensive each formed by an elastically flexible rod.
- this rod is formed in one piece with the Sprinttragerstange and thinner than this, in order to achieve the required degree of flexibility.
- the first joint preferably connects the Studentstange with a rigidly anchored to the piston and guided in the pumping chamber piston rod.
- Fig. 1 is a perspective view of a linear compressor according to the invention
- Fig. 2 in detail the Mattertragerstange, the pumping chamber and a part of
- the linear compressor shown in Figure 1 in perspective view has a rigid, in plan view in approximately U-shaped frame, which is composed of three parts, namely two flat wall pieces 1 and a sheet 2. Between facing narrow sides of the sheet 2 and the two wall pieces 1, a first diaphragm spring 3 is clamped; a second diaphragm spring 4 of the same shape as the diaphragm spring 3 is attached to the side facing away from the bow narrow sides of the wall pieces 1.
- the stamped from spring plate diaphragm springs 3, 4 each have an elongated edge strip which covers the narrow sides of the wall pieces 1, and four spring arms 5 which extend in a zigzag from the ends of the edge strips to a central portion 6, where they meet.
- the central portion 6 has three holes, two outer to which by means of screws or rivets 7, a permanent magnetic oscillating body 8 is suspended, and a central bore through which in the diaphragm spring 3 a to the oscillating body 8, z. B. by screw fastened rod portion 10 extends.
- the rod portion 10 is connected to a transmission rod 9 formed in the present case of spring steel via a flexibly flexible tapered portion 11.
- a second tapered portion 12 connects the transmission rod 11 integrally with a piston rod 13, which engages in a pumping chamber 14 supported by the arc 2, is guided through a bore in an end wall of the pumping chamber and in the pumping chamber 14 with a movable piston 15 (see Figure 2) is connected.
- Two electromagnets with E-shaped yoke and a wound around the middle leg of the E coil are each arranged between the oscillating body 8 and the wall pieces 1 with the oscillating body facing pole pieces and serve to drive a vibrating movement of the vibrating body.
- the pumping chamber 14 is annularly surrounded by a cavity 16 which communicates with the pumping chamber 14 through a plurality of openings 17 in its side wall and which is fed via a passage 18 with compressed gas branched from a pressure port 19 of the pumping chamber.
- the penetrating through the openings 17 in the pumping chamber 14 compressed gas forms on the side wall a cushion on which the piston 15 slides substantially frictionless.
- the transmitter rod 9, as shown in Figure 2 extends straight between the vibrating body 8 and the piston 15, and the directions of movement of the vibrating body 8 and the piston 15 are exactly parallel.
- deviations from such an ideal configuration always occur due to manufacturing tolerances, be it that the pump chamber 14 is not exactly aligned with the oscillating body 8, or that due to tolerances in the attachment of the diaphragm spring 3, 4 on the frame and the oscillating body. 8 the direction of movement of the oscillating body 8 does not coincide with that of the piston 15.
- FIG. 3 shows in a representation analogous to FIG. 2 the case of a lateral offset between oscillating body 8 and piston 15.
- the longitudinal axes of head portion 10 and piston rod 13 are parallel, but not collinear. The deviation is absorbed by a slight elastic bending of the tapered sections, 12 and a slight inclination of the Mattertragerstange 9.
- the piston 15 reciprocates in the pumping chamber 14, without him acting on significant tilting torques or lateral forces, the piston 15 Press against a wall of the pumping chamber 14.
- the clearance between the piston 15 and pump chamber wall can therefore be kept small, so that only a small gas flow rate is required for the storage of the piston 15 and a correspondingly high efficiency of the compressor can be achieved.
- Figure 4 shows the case of a not exactly parallel alignment of the directions of movement of the oscillating body 8 and piston 15. This is compensated by means of the flexible tapered sections 11, 12, wherein the Sprintmanbar 9, as shown in each case by dashed lines, not between the reversal points of their movement only a shift, but also performs a slight turn.
- the tapered sections 11, 12 could also be replaced by ball joints or cardan joints;
- the version with tapered sections is particularly suitable for miniaturization and inexpensive to manufacture.
