摘要： A pressure-acting chamber is defined by a first cylinder block and a spacer. The pressure-acting chamber communicates with a discharge chamber via a supply passage. A load based on the pressure difference between the pressure-acting chamber and a swash plate chamber is applied to a rotary shaft and acts toward a second thrust bearing.

摘要： 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 inner portion includes a narrow portion and a wide portion. The wide portion projects out of the narrow portion in the widthwise direction and has a larger width than the narrow portion. An outer surface of the wide portion is slidable on a wall surface of the corresponding cylinder bore when the double-headed piston reciprocates in the cylinder bores.

摘要： A control valve is disclosed that drives a valve body in a valve closing direction against urging forces of a bellows assembly and an open spring by an electromagnetic force generated in an electromagnetic coil portion by a drive current subjected to pulse width modulation. The control valve is provided with a notch portion formed in an inner peripheral wall of a through hole portion disposed in an end wall of a solenoid housing, so that a magnetic resistance between a peripheral wall of a movable iron core housed in a housing member and the inner peripheral wall of the through hole portion in a region of the notch portion differs from that in the other region around the movable iron core. In addition, a variable displacement compressor controls a refrigerant gas discharge displacement by use of this control valve.

摘要： A gasket is provided between a cylinder block and a valve plate. By providing a through hole at a position near the center of the gasket, bending moment acting on the cylinder block is reduced, and hence deformation of the cylinder block is restrained. As a result, reciprocating motion of a piston and rotational motion of a rotary valve are performed smoothly.
