Abstract

In a variable displacement compressor 100, transmitting member 116 transmits rotational motion of rotor 112 to swash plate 111 and supports swash plate 111. Guide member 117 guides inclining motion of swash plate 111 such that a top dead center position of piston 126 is maintained to be substantially constant. Members 116, 117 are separately formed at different portions on a rotor end face 112a. In the variable displacement compressor 100, first contacted member 118 contacted with transmitting member 116, and second contacted member 119 contacted with guide member 117, are separately formed at different portions on swash plate end face 111b. The transmitting member 116 and the first contacted member 118 extend on rotor 112 and swash plate 111, respectively, from a top dead center side region V1 to a bottom dead center side region V2 of the piston.

Dependent claims

A variable displacement compressor comprising:

a housing in which a cylinder bore is formed;
a drive shaft rotatably supported inside the housing;
a rotor secured to the drive shaft;
a swash plate facing the rotor and attached to the drive shaft in a manner capable of inclining with respect to the axis of the drive shaft;
and
a piston disposed in the cylinder bore and reciprocating due to rotational motion of the swash plate,
in which an inclination angle of the swash plate is changed to change a stroke amount of the piston so that a discharge displacement of refrigerant discharged from the cylinder bore is made variable,
wherein, on a rotor end face of the rotor on a swash plate side, a transmitting member that transmits rotational motion of the rotor to the swash plate and supports the swash plate, and a guide member that guides inclining motion of the swash plate such that a top dead center position of the piston is maintained to be substantially constant, are separately formed at different portions,
wherein, on a swash plate end face of the swash plate on a rotor side, a first contacted member that is contacted with the transmitting member, and a second contacted member that is contacted with the guide member, are separately formed at different portions,
wherein the transmitting member extends on the rotor from a top dead center side region to a bottom dead center side region of the piston, and the first contacted member extends on the swash plate from the top dead center side region to the bottom dead center side region of the piston.
