Definitions

  • the compressor of the present invention can exhibit sufficient controllability while realizing as small a size as possible.
  • a first sealing means for sealing the control pressure chamber may be provided between the movable cylindrical portion and the drive shaft.
  • the 2nd sealing means which seals a control pressure chamber is provided between the movable cylinder part and the fixed cylinder part.
  • the first sealing means and the second sealing means it is possible to employ various sealing materials in addition to an O-ring or the like. Further, the first sealing means and the second sealing means may be the same type or different.
  • the position where the action part is formed on the movable body and the position where the action part is formed on the swash plate can be designed as appropriate.
  • the swash plate may be defined with a top dead center corresponding portion that positions the piston at the top dead center.
  • the action part and the to-be-acted part are eccentric from the drive shaft center to the top dead center corresponding part side.
  • the drive axis of the movable body is the same when the inclination angle range is the same. The direction stroke can be reduced. Thereby, in this compressor, the enlargement of an axial length can be suppressed and the mounting property to a vehicle etc. can be improved.
  • the swash plate has a swash plate body in which an insertion hole is formed and an actuated portion fixed to the swash plate body. In this case, it is possible to increase the degree of design freedom in the swash plate body and the acted part.
  • Each lug arm 53 extends rearward from the lug plate 51.
  • the lug plate 51 is formed with a cam surface 51 b at a position between the lug arms 53. In FIG. 1 and the like, only one side of the lug arm 53 is shown for ease of explanation.
  • the actuator 13 includes a lug plate 51, a movable body 13a, and a control pressure chamber 13b.
  • the actuator 13 is adopted, and the inclination angle of the swash plate 5 is changed by the pressure change in the control pressure chamber 13b having a smaller volume than the swash plate chamber 25. For this reason, in this compressor, it is possible to reduce the amount of refrigerant required for changing the inclination angle, compared to a compressor that changes the inclination angle by changing the pressure in the swash plate chamber 25. For this reason, in this compressor, it is possible to suppress an increase in the size of the swash plate chamber 25 and consequently the housing 1.
  • the swash plate arms 5e and 5f of the link mechanism 7 transmit the rotation of the lug plate 51 to the swash plate 5 and substantially maintains the position of the top dead center corresponding portion T of the swash plate 5.
  • the change of the inclination angle is allowed.
  • the convex part 5g formed in the swash plate main body 5 is contact
  • the swash plate 5 includes a swash plate body 50, swash plate arms 5 e and 5 f, and a contact member 59.
  • This contact member 59 also corresponds to the operated part in the present invention.
  • the contact member 59 is formed with a convex portion 59a protruding forward.
  • the convex portion 59a is formed in a substantially hemispherical shape.
  • the convex part 59a is in point contact with the action surface 134a of the action part 134 at the action position F.
  • the action part 134 and the contact member 59 are in contact with each other through the action surface 134a and the convex part 59a at a position eccentric from the drive axis O to the top dead center corresponding part T side of the swash plate 5.
  • Other configurations of the compressor are the same as those of the compressor according to the first embodiment, and the same components are denoted by the same reference numerals and detailed description thereof is omitted.
  • this compressor since the swash plate 5 and the contact member 59 are separate, it is possible to increase the degree of freedom in designing the swash plate body 50 and the contact member 59.

Abstract

　La présente invention concerne un compresseur de type à plateau oscillant à cylindrée variable qui peut être fabriqué de manière aussi compacte que possible tout en présentant une capacité de commande suffisante. Ce compresseur est pourvu d'un actionneur (13). L'actionneur (13) comprend un corps mobile (13a) et une chambre de pression de commande (13b). L'actionneur (13) comprend une première partie formant cylindre mobile (131) et une partie travaillante (134) fait saillie au niveau de l'extrémité arrière de la première partie formant cylindre mobile (131). Une surface travaillante plate (134a) est formée dans la partie travaillante (134). Une partie convexe (5g) est formée dans un corps principal (50) de plateau oscillant dans le compresseur. La partie convexe (5g) est positionnée sur un côté d'une surface avant (5a) du corps principal (50) de plateau oscillant qui fait face à une partie correspondante (T) de point mort haut d'un plateau oscillant (5). Dans ce compresseur, la partie travaillante (134) et la partie convexe (5g) entrent en contact en une position excentrique en direction de la partie correspondante (T) de point mort haut à partir d'un centre axial d'entraînement (O).
