摘要： A variable displacement swash plate type compressor includes a rotary shaft, a swash plate, and an actuator capable of changing the inclination angle of the swash plate. The actuator includes a movable body. The movable body includes a sliding portion that slides on the rotary shaft or the lug member and a movable body-side transmission portion that engages with the swash plate at a position radially outward of the rotational axis of the swash plate. The movable body-side transmission portion is configured such that a perpendicular line or a normal to the movable body-side transmission portion and the rotational axis of the rotary shaft intersect with each other in a zone surrounded by the sliding portion when viewed in a direction that is perpendicular to a direction in which the rotational axis of the rotary shaft extends and perpendicular to the first direction.

摘要： In the compressor of the present invention, guide surfaces 57a and 57b are formed on a lug plate 51 and guided surfaces 59a and 59b are formed on swash plate arms 5e and 5f. The guide surfaces 57a and 57b and the guided surfaces 59a and 59b are respectively in linear contact with one another at a first abutment position P1 when an inclination angle is maximum and are in linear contact with one another at a second abutment position P2 when the inclination angle is minimum. The guide surfaces 57a and 57b are formed such that portions between the first abutment position P1 and the second abutment position P2 are convex toward the guided surfaces 59a and 59b. In the compressor, a contact angle θ1 at the first abutment position P1 can be made large, and a contact angle θ2 at the second abutment position P2 can be made small.

摘要： A swash plate type variable displacement compressor includes a housing (1) having a suction chamber (33), a discharge chamber (35), a swash plate chamber (25), and a plurality of cylinder bores (21A), a drive shaft (3), a swash plate (5), a link mechanism (7), a plurality of pistons (9), a conversion mechanism (11A, 11B), an actuator (13) that changes the inclination angle of the swash plate (5), and a control mechanism (15) that controls the actuator (13). The link mechanism (7) allows a change in an inclination angle of the swash plate (5) with respect to a plane extending perpendicularly to the axis of rotation (O) of the drive shaft (3). The conversion mechanism (11A, 11 B) converts the rotation of the swash plate (5) into reciprocal movement of the pistons (9) with a stroke length according to the inclination angle of the swash plate (5).

摘要： A piston-type compressor includes a housing, a drive shaft supported on the housing, a communication hole formed inside the drive shaft, a valve mechanism, and a cylindrical body. The cylindrical body is inserted in the communication hole to disconnect a residual gas bypass passage and the communication hole from each other and to open the interior space of the cylindrical body to the communication hole. The valve mechanism includes an annular space defined outside the cylindrical body in the communication hole and multiple connection holes providing communication between the annular space and communication passages. The residual gas bypass passage is formed of the annular space and the multiple connection holes.

摘要： A swash plate compressor comprises a swash plate actuator (13) having a lug member (51), a movable body (13a), and control pressure chamber (13b) therebetween which moves the movable body in the axial direction by an internal pressure. A first acting portion (134) and a second acting portion (135) are formed at a rear end of a first cylinder portion (131) of the movable body (13a). The first and the second acting portions (134,135) are formed by stepping across a top dead center surface (F), and are plane-symmetrical with respect to the top dead center surface (F). Further, an affected portion (5f) is formed on a front surface (5a) of the swash plate (5). The first and the second acting portions (134,135) and the affected portion (5f) are located eccentrically to a top dead center position corresponding portion (T) side from a drive shaft axis (O). In the compressor, at a time of decreasing an inclination angle of the swash plate (5), the first acting portion (134) and the second acting portion (135) separately press the affected portion (5f) with the top dead center surface (F) as a reference. Thereby, in the compressor, at the time of decreasing the inclination angle of the swash plate (5), the movable body (13a) favorably moves in a drive shaft axis (O) direction.

摘要： A variable displacement swash plate type compressor comprises an actuator (13) for changing the inclination angle of the swash plate (5) inside the swash plate chamber (25). Said actuator (13) includes a defining body (51c) provided on the drive shaft (3), a movable body (134) movable in axial direction of the drive shaft (3) and a control pressure chamber (13b) defined by the defining body (51c) and the movable body (134). A control mechanism (15) is configured to control the actuator (13), wherein refrigerant is introduced into the control pressure chamber (13b) via a supply passage (3a,3b) and discharged from the control pressure chamber (13b) via a bleed passage. Said bleed passage includes a throttle hole (57) formed in at least one of the defining body (51c) and the movable body (134). Lubricant is discharged through the throttle hole (57) together with the refrigerant gas. Consequently, in the compressor, the lubricant is less easily stored in the control pressure chamber (13b), and lubricant shortage in the swash plate chamber (25) less easily occurs.
