Abstract: A hydraulic system for an active chassis, including a motor-pump group with a pump casing with a mounting section with integrated fluid interface with first and second fluid openings, and a load with a casing with corresponding mounting section and corresponding fluid interface. The load can be mounted on the pump casing in such a manner that the fluid openings are disposed mutually opposite.

Abstract: A damping arrangement for an axle of an active chassis of a motor vehicle. A damping system interacts with each wheel of the axle, each damping system has the following: a damper having a double-acting hydraulic cylinder and a piston, a hydraulic pump and an electric motor for driving the hydraulic pump, a hydraulic unit having a hydraulic reservoir and valves. The hydraulic pump and the hydraulic unit of the respective damping system interact with the respective hydraulic cylinder in such a manner that, depending on the conveyance direction of the hydraulic pump, a movement of the piston can be provided in a first or in a second actuation direction. The electric motors of both damping systems are arranged with axially aligned rotational axes in a casing and can be regulated by a common control device which has electronic construction groups which are arranged on at least one circuit board.

Abstract: An apparatus for making available hydraulic energy, in particular in a chassis system of a vehicle, including at least one motor-pump group and an electronic unit for regulating the motor-pump group. The motor-pump group is arranged in a motor-pump casing that forms a motor-pump housing or is a part of a motor-pump housing. Th electronic unit is arranged in an electronic-unit casing that forms an electronic-unit housing or is a part of an electronic-unit housing, and the electronic unit and the motor-pump group are electrically connected via a supply string.

Abstract: A device for supplying hydraulic energy in a chassis system of a vehicle includes a first hydraulic pump and a first electric motor for driving the first hydraulic pump, a second hydraulic pump and a second electric motor for driving the second hydraulic pump, and a common electronic unit which is arranged to control the first and the second electric motor, wherein the two electric motors and the two pumps are preferably designed to be identical in structure and/or respectively form first and second motor-pump groups.

Abstract: In a hydraulic system which is biased to a minimum system pressure using a bias valve or other flow obstruction disposed in a tank line, there is provided in a bypass line to the bias valve an evacuating and filling valve through which the hydraulic system is first evacuatable and subsequently fillable with a hydraulic fluid. The valve closes the bypass when a differential pressure overcomes a preadjusted force of a spring element. For this purpose, the valve possesses a displaceably mounted valve body with an integrated throttle and a seal face which closes a through opening when the valve body is shifted against the bias force of the spring element due to the pressure difference.
