Abstract: A control valve is used for a variable displacement compressor. The compressor has a crank chamber and a supply passage. The control valve includes a valve housing. A valve chamber is defined in the valve housing. A valve body is accommodated in the valve chamber for adjusting the opening size of the supply passage. A pressure sensing chamber is defined in the valve housing. A pressure sensing member separates the pressure sensing chamber into a first pressure chamber and a second pressure chamber. The pressure at a first pressure monitoring point is applied to the first pressure chamber. The pressure at a second pressure monitoring point located is applied to the second pressure chamber. The pressure sensing member moves the valve body in accordance with the pressure difference between the first pressure chamber and the second pressure chamber. The pressure sensing member is a bellows or a diaphragm, an actuator applies force to the pressure sensing member in accordance with external commands. The force is applied by the actuator corresponds to a target value of the pressure difference. The pressure sensing member moves the valve body such that the pressure difference seeks the target value.

Abstract: A variable displacement compressor has a crank chamber defined in a housing. A drive shaft is arranged in the housing. A piston is accommodated in the cylinder bore. A swash plate is connected to the piston to convert a rotation of the drive shaft. A retainer surface is arranged in the housing and extends substantially perpendicular to the axis of the drive shaft. A restricting mechanism is arranged between the swash plate and the retainer surface. The restricting mechanism receives the swash plate and restricts movement of the swash plate when the inclination of the swash plate decreases.

Abstract: A hydrostatic axial piston machine employs a swash plate construction in which the diagonal position of the swash plate can be controlled by at least one positioning piston pressurized with a control pressure. A control valve is in a line which leads to at least one positioning piston. A simple electrical-hydraulic control of the swash plate can be accomplished by the electrical actuation of the control valve. The control valve may be in the form of a rotary disk valve which can be actuated by a stepper motor.
