摘要： A swash plate type variable displacement compressor includes a collection and supply mechanism. The collection and supply mechanism has collection passages, supply passages, an annular space, an inlet port, and an outlet port. The inlet port is communicable with a working collection passage of the collection passages. The outlet port is communicable with a working supply passage of the supply passages. When the inclination angle of the swash plate is maximum, residual refrigerant gas in a compression chamber of collection phase is collected through the working collection passage and the collected refrigerant gas is supplied to a compression chamber of supply phase. On the other hand, when the inclination angle is less than the maximum, residual refrigerant gas is supplied no more into the supply-phase compression chamber.

摘要： In a compressor that changes a discharge capacity by using an actuator, a variable displacement swash plate type compressor capable of realizing reduction in manufacture cost is provided.In the compressor of the present invention, a ring groove is formed in a movable body, and the ring groove is provided with an annular member. The annular member has a joint gap formed by a first to a third cutouts, and the third cutout is an aperture. In this compressor, the annular member moves in the ring groove based on a pressure difference between a control pressure chamber and a swash plate chamber. Thereby, in the compressor, a pressure in the control pressure chamber is regulated by regulating a flow of a refrigerant that flows to the swash plate chamber from the control pressure chamber.

摘要： In a swash plate type variable displacement compressor, a lug plate includes a cylinder chamber and first and second guide surfaces. Inner peripheral edges of the first and second guide surfaces are defined respectively at parts where the peripheral edge of the cylinder chamber and the guide surfaces overlap with each other. When the inclination angle of a swash plate of the compressor is maximum, first and second guided surfaces and the first and second guide surfaces, respectively are brought into line contact with each other at a first position. At this time, first and second slide contact widths are maximum. When the inclination angle of the swash plate is minimum, the first and second guided surfaces and the first and second guide surfaces, respectively are brought into line contact with each other at a second position. At this time, the first and second slide contact widths are minimum.

摘要： A variable displacement swash-plate compressor includes an actuator that changes the inclination angle of a swash plate. The actuator includes a movable body that moves along a drive shaft axis. The movable body includes an acting portion that pushes the swash plate. The swash plate includes a receiving portion that contacts and is pushed by the acting portion. The acting portion and the receiving portion contact each other at an acting position. A bottom dead center associated part for positioning the piston at a bottom dead center is defined on the swash plate. When the drive shaft and the acting position are viewed from a direction that is perpendicular to a top dead center plane containing the top dead center associated part and the drive shaft axis, the acting position is defined at a position overlapping with the drive shaft regardless of the inclination angle.

摘要： A swash plate type variable displacement compressor according to the present invention includes a housing having a suction chamber, a discharge chamber, a swash plate chamber, and a plurality of cylinder bores, a drive shaft, a swash plate, a link mechanism, a plurality of pistons reciprocally received in the respective cylinder bores, a conversion mechanism, an actuator that changes the inclination angle of the swash plate, and a control mechanism that controls the actuator. The link mechanism disposed between the drive shaft and the swash plate allows a change in inclination angle of the swash plate with respect to a plane extending perpendicularly to the axis of rotation of the drive shaft. The conversion mechanism converts the rotation of the swash plate into reciprocal movement of the pistons in the cylinder bores with a stroke length according to the inclination angle of the swash plate.

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： A variable displacement swash-plate compressor includes an actuator that is configured to change the inclination angle of a swash plate. The actuator includes a movable body that moves along a drive shaft axis. The movable body includes an acting portion that is configured to push the swash plate with the pressure in a control pressure chamber. The swash plate includes a receiving portion that contacts and is pushed by the acting portion. The acting portion and the receiving portion contact each other at an acting position. A drive-shaft-parallel line segment is defined that contains the acting position and connects a proximal end of the acting portion and a proximal end of the receiving portion to each other, while extending in parallel with the drive shaft axis. The drive-shaft-parallel line segment is shorter when the inclination angle of the swash plate is maximized than when the inclination angle is minimized.
