Variable Displacement Compressor

Abstract

A linkage mechanism ( 40 ) of a variable displacement compressor includes an arm ( 41 ) extending from a rotating member ( 21 ) toward a tilting member ( 24 ), an arm ( 43 ) extending from the tilting member ( 24 ) toward the rotating member ( 21 ) and receiving rotary torque from the arm ( 41 ) of the rotating member, a pin ( 51 ) fixed to one of the arm ( 41 ) of the rotating member and the arm ( 43 ) of the tilting member, and an axial direction load receiving face ( 53 ) formed on the other of the arm ( 41 ) of the rotating member and the arm ( 43 ) of the tilting member and configured to contact with the pin ( 51 ) to receive axial a direction load applied between the rotating member ( 21 ) and the tilting member ( 24 ).

1 . A variable displacement compressor, comprising:
 a drive shaft;   a rotating member fixed to the drive shaft and rotating integrally with the drive shaft;   a tilting member attached to the drive shaft and being changeable a tilt thereof with respect to an axis of the drive shaft;   a linkage mechanism configured to rotate the rotating member and the tilting member integrally with allowing the tilt of the tilting member to change; and   a piston reciprocating in a cylinder bore corresponding to rotary movement of the tilting member; wherein   the linkage mechanism includes:   an arm extending from the rotating member;   an arm extending from the tilting member and overlapping with the arm of the rotating member in a rotating direction;   a pin fixed to one of the arm of the rotating member and the arm of the tilting member; and   an axial direction load receiving face formed on the other of the arm of the rotating member and the arm of the tilting member and configured to contact with the pin to receive an axial direction load applied between the rotating member and the tilting member.   
   
   
       2 . The variable displacement compressor according to  claim 1 , wherein the arm of the rotating member is formed in a bifurcated shape divided by a slit to slidably hold the arm of the tilting member in a sandwiching manner. 
   
   
       3 . The variable displacement compressor according to  claim 1 , wherein the arm of the tilting member is formed in a bifurcated shape divided by a slit to slidably hold the arm of the rotating member in a sandwiching manner.
