Definitions

  • a piston is contained in each of a plurality of cylinder bores defined in a housing.
  • a rotor is provided to a drive shaft that is rotatably supported by the housing. The rotor rotates integrally with the drive shaft.
  • a cam plate (swash plate) is supported slidably and tiltably by the drive shaft.
  • a hinge mechanism is provided between the rotor and the cam plate. The rotary motion of the drive shaft is converted into the reciprocating motion of the pistons through the rotor, the hinge mechanism, and the cam plate. Accordingly, the compression of a refrigerant gas is performed.
  • the hinge mechanism guides the cam plate so that the cam plate slides on the drive shaft while tilting. According to an inclination angle of the cam plate, the stroke of the pistons, that is, the displacement of the variable displacement compressor is changed.
  • Cylinder bores 22 are formed in the above-mentioned cylinder block 11.
  • the cylinder bores 22 are arranged at equal angular intervals around the axis L of the drive shaft 16.
  • the cylinder bores 22 are extended along with the axis L of the drive shaft 16.
  • a single-headed piston 23 is accommodated in each of the cylinder bores 22.
  • Each piston 22 reciprocates in the corresponding cylinder bore 22.
  • Front and back openings of each of the cylinder bores 22 are blocked by a front end face 13a of a valve and port assembly 13 and a corresponding one of the pistons 23, respectively, and a compression chamber 24, the volume of which changes according to the reciprocating motion of the corresponding one of the pistons 23, is provided in that one of the cylinder bores 22.
  • Cylinder faces 45b and 46b which are convex surfaces, are formed at ends of the above-mentioned swash-plate-side protrusions 45 and 46, respectively.
  • the main axis S of the respective cylindrical faces 45b and 46b is perpendicular to the side faces 45a and 46a.
  • the ends of the respective swash-plate-side protrusions 45 and 46 slidably abut against the cam face 47a of the corresponding cam portion 47 through the cylindrical faces 45b and 46b. Therefore, the axial load that acts on the swash plate 18 because of compression reaction force etc. is received by the cam face 47a of the cam portion 47 through the cylindrical faces 45b and 46b of the swash-plate-side protrusions 45 and 46.
  • a protruding portion 73 is provided in a position corresponding to the engaging groove 70.
  • the protruding portion 73 transmits power to a side face 71a of the wall portion 71 in the swash plate 18 with a side face 73a in the state of being inserted and engaged between the side faces (wall surfaces) 71a and 72a of the wall portions 71 and 72, which face each other (when the rotational direction of the drive shaft 16 is the direction shown by the arrow R).
  • the protruding portion 73 transmits power to the side face 72a of the wall portion 72 in the swash plate 18 with a side face 73b.
