Abstract:
A pressure medium supply unit for a hydraulic system of a motor vehicle that includes a clutch requiring a high hydraulic pressure and a low volumetric flow rate of hydraulic fluid for operation, and an automatic transmission requiring a low hydraulic pressure and a high volumetric flow rate of hydraulic fluid for operation. A single hydraulic pump is provided to supply hydraulic fluid to both the clutch and the transmission.
Abstract:
A hydraulic system comprising a pump for feeding hydraulic fluid from an inlet side to an outlet side, wherein a pressure accumulator is disposed at the outlet side, wherein between the pump and the pressure accumulator a hydraulic control valve is disposed, which has at least two valve positions, wherein the outlet side of the pump is connected to the pressure accumulator in a first valve position, and separated from the pressure accumulator in a second valve position, wherein the outlet side of the pump is connected to the inlet side through the control valve in the second valve position.
Abstract:
A device for detecting the position of a hydraulic piston-cylinder system, where the hydraulic piston-cylinder system is connected to a position-detecting means which comprises a magnet and a Hall sensor and the connection between the hydraulic piston-cylinder system and the position-detecting means comprises a lever.
