Variable capacity compressor

Abstract

A variable capacity compressor includes a rotating member 21 fixed to a drive shaft 10 so as to rotate with the drive shaft 10, a sleeve 22 axially slidably attached to the drive shaft 10, a tilting member 24 tiltably attached to the sleeve 22 by a pivot pin 61, a linkage mechanism 40 connecting the rotating member 21 with the tilting member 24 and configured to transfer a rotary torque of the rotating member 21 to the tilting member 24 as allowing the tilting member to be tiltable, and a tilting guide face 22 c formed on the sleeve 22 and a tilting guide face 25 d formed on the tilting member 24 which are formed as planes orthogonal to the pivot pin 61 and are configured to slidingly contact one another.

1 . A variable capacity compressor comprising:
 a rotating member fixed to a drive shaft and configured to rotate integrally with the drive shaft;   a sleeve axially slidably attached to the drive shaft;   a tilting member tiltably attached to the sleeve by a pivot pin;   a linkage mechanism connecting the rotating member with the tilting member and configured to transfer a rotary torque of the rotating member to the tilting member as allowing the tilting member to tilt;   a piston configured to reciprocate in response to rotation of the tilting member;   tilting guide faces respectively formed on the sleeve and the tilting member, the tilting guide faces formed as planes orthogonal to the pivot pin and configured to slidingly contact one another.   
   
   
       2 . The variable capacity compressor according to  claim 1 , wherein
 the linkage mechanism comprising:   an arm extending from a rotating member toward the tilting member;   an arm extending from the tilting member toward the rotating member; and   a linking pin pivotally connecting the arm of the rotating member and the arm of the tilting member directly or indirectly.   
   
   
       3 . The variable capacity compressor according to  claim 1 , wherein
 the linkage mechanism comprising:   a pair of opposite arms extending from the rotating member toward the tilting member;   a pair of opposite arms extending from the tilting member toward the rotating member;   a linkage member having a first end that is slidably fit between the arms of the rotating member and a second end that is slidably fit between the arms of the tilting member,   a first linking pin pivotally connecting the first end of the linkage member and the arms of the rotating member; and   a second linking pin pivotally connecting the second end of the linkage member and the arms of the tilting member.   
   
   
       4 . The variable capacity compressor according to  claim 3 , wherein
 a pair of tilting guides of the sleeve and a pair of the tilting guides of the tilting member are provided on both sides of the driving shaft, and   a width between the pair of tilting guides of the sleeve is larger than a width of the first end of the linkage member and a width of the second end of the linkage member.
