Abstract: A double-headed piston type swash plate compressor includes a rotation shaft, a housing, a swash plate, two cylinder bores, a double-headed piston, and two shoes. The double-headed piston includes two shoe holders, a neck, two heads, and two coupling portions. At least one of the two coupling portions includes a load receiving portion. The load receiving portion is configured to receive bending load that is applied from the swash plate to the double-headed piston and acts toward an inner side in the radial direction. The load receiving portion is separated from the wall surface of the cylinder bore when load applied to the double-headed piston is less than a specific threshold value. The load receiving portion abuts against the inner wall of the cylinder bore and receives the bending load when the load applied to the double-headed piston is greater than the specific threshold value.

Abstract: An actuator of a variable displacement swash compressor includes a partitioning body that is movable along the axis of a drive shaft, a movable body that changes the inclination angle of a swash plate, and a control pressure chamber defined by the partitioning body and the movable body. The movable body is moved by drawing refrigerant in the control pressure chamber from a discharge chamber. The swash plate is configured to contact and move the partitioning body as the inclination angle increases.

Abstract: A double-headed piston type swash plate compressor includes a rotation shaft, a housing, a swash plate, two cylinder bores, a double-headed piston, and two shoes. The double-headed piston includes two shoe holders, a neck, two heads, and two coupling portions. Each of the coupling portions includes an outer portion and an inner portion. A direction orthogonal to both of an opposing direction of the inner portion and the outer portion and the axial direction of the double-headed piston is referred to as a widthwise direction. The neck is larger in the widthwise direction than in the opposing direction so that the neck is deformable in the opposing direction. Each of the two coupling portions has a width that is less than or equal to a width of the neck. The inner portion includes a narrow portion. The narrow portion is at least partially located closer to the head than the shoe holder in the inner portion. The two coupling portions are deformable in the widthwise direction when the swash plate applies load to the double-headed piston.

Abstract: Provided is a compressor, in which the inclination angle of a swash plate is changed by an actuator, ensuring stability on a product-by-product basis while realizing reduction in size. In the compressor, when pressure in a control pressure chamber increases, a movable body moves toward a flange. At this time, the movable body pulls the opposite end side of a swash plate rearward in a swash plate chamber via first and second pulling arms. A link mechanism permits increase of the inclination angle of the swash plate until reaching a maximum value. When the pressure in the control pressure chamber reaches a required control pressure, a rear wall of the movable body which has moved rearward in the swash plate chamber abuts a front face of the flange. This makes it possible in this compressor to restrict the maximum value of the inclination angle of the swash plate.
Abstract translation: 提供了一种压缩机,其中斜盘的倾斜角由致动器改变,确保了在逐个产品的基础上的稳定性,同时实现尺寸的减小。 在压缩机中,当控制压力室中的压力增加时,可移动体向凸缘移动。 此时,可移动体经由第一和第二牵引臂在斜盘室中向后拉动旋转斜盘的相对端侧。 连杆机构允许增加斜板的倾斜角度直到达到最大值。 当控制压力室中的压力达到所需的控制压力时,在斜盘室中向后移动的可移动体的后壁抵靠凸缘的前表面。 这使得在该压缩机中可以限制斜盘的倾斜角度的最大值。

The plug portion is to be inserted into a fluid port of a compressor to plug the fluid port. The plate-like body portion integrally joins the plug portion, the bolt insertion portion, and the tab portion. The bolt insertion portion extends from a front surface of the body portion. The tab portion is formed on the front surface of the body portion. The plug portion is projectingly formed on a rear surface of the body portion. The tab portion includes a ring having an annular shape, and is located opposite to the bolt insertion portion across the plug portion. The ring has an opening that extends through the ring in a direction that crosses insertion direction of the plug portion.
