Abstract: A housing of a scroll type expansion machine includes: a suction port formed at a position on the opposite side to a drive shaft with a fixed scroll interposed therebetween; a discharge port formed on the side of a drive-side bearing closer to the tip end of the drive shaft; a low pressure chamber formed on the outer side of an orbiting-side scroll portion when viewed from the axial direction of the drive shaft; and a tip end-side low-pressure space being a space in which a sealing member is disposed, and has: a partition wall partitioning the tip end-side low-pressure space and the low-pressure chamber from each other; and a communication space communicating the tip end-side low-pressure space with the low-pressure chamber.

Abstract: A swash-plate-type variable displacement compressor is provided with a rotationally-driven drive shaft, a lug plate integrally fixed to the drive shaft, a swash plate fixed in a manner capable of being variably inclined to the drive shaft, a link mechanism for coupling the lug plate and the swash plate while permitting the variable inclination; and an actuator which is arranged between the lug plate and the swash plate and which uses pressure to change an inclination angle of the swash plate. The actuator has a cylindrical member which extends from a surface of the lug plate toward the swash plate, a bottomed cylindrical member fitted capable of being relatively displaceable to an outer peripheral surface of the cylindrical member, and a coil spring which is arranged in an inner space of the actuator, and which biases the bottomed cylindrical member in a direction which is away from the lug plate.

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.
