Abstract (en)

[origin: EP2354548A1] The power conversion mechanism of a variable displacement reciprocating compressor includes a joint shaft (54) that is fitted to a drive shaft (30) through a bearing (56) and supported by an inner circumferential face of a support hole (58) formed in the cylinder block (20) so as not to be relatively rotatable but to be slidable relative to the inner circumferential face; a joint case (66) that is integrally and tiltably formed in the conversion mechanism (38); and a plurality of balls (74) rollably held between JS-side protrusions that are integrally formed in the joint shaft (54) and JC-side protrusions (62) that are integrally formed in the join case (66). The variable suction throttle mechanism of the compressor uses the sliding movement of the joint shaft (54) to change air-flow resistance in a valve chamber (101) communicating with the support hole (58).
