Definitions

  • the invention relates to a reciprocating engine with a in their inclination adjustable to the machine shaft, driven by the machine shaft Swivel disc by placing both with one on the Maschjnenwelle axially guided sliding body as well as with distance from the engine shaft with a driving force transmitting Carrier is pivotally connected, wherein the pistons each have a hinge assembly have, on which the swash plate in sliding engagement stands.
  • a reciprocating engine of this type is known from DE-A-44 11 926 (Japanese Patent Publication No. 081944).
  • This machine is the driver two-piece, with a fixed to the machine shaft first driver part arranged at a considerable distance next to the swash plate is and a second, in the first hingedly engaging driver part forms a lateral extension of the swash plate.
  • This Construction has the disadvantage that it is the minimum axial length of the machine significantly influenced.
  • the one thickened Nubenteil having swash plate through its lateral extension a relatively large moment of inertia with a considerable amount of the axis of rotation away from the center of gravity, causing a sudden change the rotational speed with appropriate inertia to a Tilt adjustment of the swash plate leads.
  • the invention is based on the object, a reciprocating engine to find the type mentioned, with little effort for their manufacture allows a particularly compact design, the one Adjusting movement of the swash plate low inertia and friction forces opposing and preventing a harmful space, ensures exact compliance with the internal dead center position of the reciprocating.
  • the Swivel disk has the shape of an annular disk and at one point of its Scope an at least radially inwardly open engagement space in which the head of one fixed to the machine shaft Driver engages.
  • the reciprocating engine 1 has, for example, seven pistons 2, which in Circumferential direction of the machine are arranged side by side and in Cylinder bores 3 of the machine housing are performed.
  • the lifting movement the piston 2 is made by engaging one of the machine shaft 5 obliquely extending annular disc 6 in an engagement chamber 7 adjacent to the closed cavity 8 of the piston 2 is provided.
  • Ball segments 11,12 provided so that the swash plate 6 at her Circulation between them slides.
  • the drive transmission from the machine shaft 5 to the annular disc 6 takes place by a driving pin fixed in the machine shaft 5 13, for example, the spherical head 15 in a radial bore 16 of the annular disc 6 engages.
  • a driving pin fixed in the machine shaft 5 13, for example, the spherical head 15 in a radial bore 16 of the annular disc 6 engages.
  • this center lies on a circle line, which is the geometric one Axles of the seven pistons connects to each other and continue on one Circular line, which are the centers of the spherical shape of the joint body 11,12 the piston 2 connects.
  • the head shape of the free driver end makes the change possible the inclination of the annular disc 6, by the driving head 15th a bearing body for the stroke of the piston 2 changing Pivoting movement of the annular disc 6 forms.
  • the shape of the intervention space 16 and / or the head 15 of the driver 13 can to achieve Another type of kinematics can be chosen differently.
  • the bearing axis 20 by two equiaxed on both sides of a Sliding sleeve 21 bearing bearing pin 22,23 formed, which also are mounted in radial bores 24,25 of the annular disc 6.
  • the Sliding sleeve 21 has for this purpose preferably on both sides bearing sleeves 26,27, the annular space 28 between the sliding sleeve 21 and the annular disc 6 bridge like a spokes.
  • the force for the angular adjustment of the annular disc 6 and thus for a regulation of the machine results from the sum of each On both sides of the piston 2 against each other acting pressures, so that these Force is dependent on the pressure in the drive chamber 33.
  • This pressure can be a flow connection with an external one Be provided compressed gas source. The higher the pressure on the engine room side the piston 2 or in the drive chamber 33 relative to the pressure on the opposite side of the piston 2, the smaller the stroke the piston 2 and thus the capacity of the machine.
  • the adjustment of the position of the sliding sleeve 21 and thus the stroke the piston for regulating the capacity of the machine can also by at least one cooperating with the sliding sleeve 21 Spring 34,35 done.
  • the sliding sleeve 21st enclosed between two coil springs 34,35, which on the Scope of the machine shaft 5 are arranged.
  • Swivel disk 6 results from their limited to the ring shape Designing the further advantage of a considerably simplified production, especially in the fine machining of their side surfaces Lapping.
  • the annular disc in the machine housing claimed only a limited space, so that also in the axial direction of the Machine a particularly compact design is possible and their installation is favored as a compressor of a vehicle air conditioning system.
