摘要： A compressor includes a rotary shaft, a rotating body, a fixed body, a vane, and a compression chamber. The vane has a vane end that contacts the surface of fixed body. The fixed body surface includes two curved surfaces. The curved surface includes a convex surface and a concave surface. The convex surface has a convex surface inner end and a convex surface outer end. The curvature of the convex surface inner end is greater than the curvature of the convex surface outer end. The concave surface has a concave surface inner end and a concave surface outer end. The curvature of the concave surface inner end is greater than the curvature of the concave surface outer end.

摘要： A compressor includes a rotary shaft, a housing in which a suction port through which a suction fluid is drawn in and a discharge port through which a compression fluid is discharged are formed, and that houses the rotary shaft, and compression chambers. The suction fluid is drawn into the compression chambers. Respective volumes of the compression chambers are periodically changed with rotation of the rotary shaft. The phases of volume changes of the compression chambers are mutually shifted. The compressor includes a communication mechanism switched between a communicating state in which the compression chambers communicate with each other, and a non-communicating state in which the compression chambers do not communicate with each other.

摘要： A compressor includes two rotors opposed to each other in an axial direction, and a vane contacting the rotors. While the vane is moved in the axial direction with rotation of the rotors, the vane is restricted from rotating by a vane groove. The compressor includes compression chambers in which suction and compression of fluid are performed with rotation of the rotors, and a communication mechanism switched between a communicating state in which the compression chambers communicate with each other, and a non-communicating state in which the compression chambers do not communicate with each other.

摘要： A compressor includes a rotary shaft, a front rotor including a front rotor surface, an intermediate wall portion including a first wall surface opposed to the front rotor surface in an axial direction, and a vane that is inserted into a vane groove formed in the intermediate wall portion and is moved in the axial direction with rotation of the front rotor. The vane includes a first vane end that is an end in the axial direction and contacts the front rotor surface. The first vane end is curved so as to be convex toward the front rotor surface and extends in the direction perpendicular to the axial direction. The front rotor surface includes a front curving surface curved in the axial direction so as to be displaced in the axial direction in accordance with its angular position.

摘要： A variable displacement type swash plate compressor includes a housing having therein a swash plate chamber and a plurality of cylinder bores, a drive shaft, a swash plate, and a link mechanism and a plurality of pistons. The compressor further includes a partitioning body, a movable body, a control chamber, a control mechanism and a connecting mechanism. The connecting mechanism includes first and second arms, a traction portion, and a link pin. The first and second arms have first and second guide surfaces that are placed in contact with the link pin. The link pin is held by the traction portion so as to be rollable on the first and second guide surfaces, respectively. A restrictor is provided on the ling pin or in the first and second arms so as to prevent the link pin from moving in a direction of an axis thereof.

摘要： In a variable displacement type swash plate compressor, a connecting mechanism that connects a movable body and a swash plate includes a first arm having a first guide surface and a second arm having a second guide surface. The first and second arms extend from the movable body toward the swash plate and disposed on opposite sides of an imaginary plane that is defined to extend passing through a top dead center portion and an axis of rotation. The first arm and the second arm have a first opening and a second opening, respectively, that are open in a direction opposite to a direction in which a link pin moves on the first guide surface and the second guide surface with an increase of the inclination angle of the swash plate.

摘要： A rear housing includes a first passage extending from an accommodation chamber towards a communication hole of a valve-forming plate. A cylinder block includes a connection portion to be connected to an external device, an outlet space opening towards the connection portion, and a second passage extending from the outlet space towards the communication hole of the valve-forming plate. A discharge passage includes a discharge chamber, the accommodation chamber, the first passage, the communication hole, the second passage, and the outlet space. The flow passage area of the communication hole is larger than at least one of the flow passage area of the first passage and the flow passage area of the second passage. The discharge passage can be designed with high flexibility.
