摘要： The invention relates to a hydraulic transmission unit for an actuator, which hydraulic transmission unit can be filled with a hydraulic fluid and has a first and a second chamber which are hydraulically interconnected and of which one is designed as a drive chamber and the other one is designed as an output chamber. At least in the first chamber, a piston is arranged movably along a piston axis, such that this piston subdivides the first chamber into a variable-volume working chamber and a rear-side chamber, the rear-side chamber being delimited at least partially by a bellows element having a variable axial length. The invention further relates to an actuator having such a hydraulic transmission unit.

摘要： Systems, methods and devices are described providing a selective hydraulic or electrically powered prime mover that is a bi-directional power unit system, including movement within a device used to compress and/or expand a fluid and provide fluid movement. The use of a hydraulic power unit is involved and comprises at least a pump or other fluid moving device, a first set of selective control valves delivering pressurized fluid to the device(s), and a second set of selective control valves returning unpressurized fluid from the device(s), a reservoir comprising a compensator tank, a port for operation at ambient pressure, and a pressure measuring device measuring ambient pressure allowing for unbalanced flow to and from the device as well as thermal expansion or compression. The use of a multiport and in some cases a swashplate pump that incorporates the features and functions of several valves for the system is also described.

摘要： An accumulator includes a housing, a flexible bladder and a support. The housing includes a chamber having a defined volume and a passage extending through the housing. The flexible bladder is positioned within the chamber and contains a compressible gas. The bladder being operable in an expanded condition and a partially collapsed condition. The support is positioned in the chamber and engages the flexible bladder when the flexible bladder is in the expanded condition. Liquid is positioned in the chamber and in contact with the flexible bladder. A volume of the liquid within the chamber is at a minimum when the flexible bladder is in the expanded condition. The volume of liquid within the chamber increases as a pressure of the liquid increases to compress the gas and operate the flexible bladder in the partially collapsed condition.

摘要： A piston accommodated in an internal space of a cylinder and forming a pair of pressure chambers together with the cylinder, the piston being configured to move relative to the cylinder; a first actuator connected to one pair of pressure chambers; a second actuator connected to the other of the pair of pressure chambers; a position detector configured to detect a position of the piston relative to the cylinder; a pressure detector configured to detect a pressure of one pair of pressure chambers; and a controller configured to control the first actuator and the second actuator. The controller controls one of the first actuator and the second actuator that the position detected by the position detector is made close to a target position and controls the other of the first actuator and the second actuator that the pressure detected by the pressure detector is made close to a target pressure.

摘要： In order to provide a master cylinder, in particular for a clutch system, an actuating system or a braking system of a vehicle, which enables secure sealing of the cylinder chamber relative to the outside, as well as a reliable flow of hydraulic medium into the cylinder chamber, it is proposed that the piston comprises a first section which has a cylindrical lateral surface and a second section which has at least one region which is set back radially inwardly with respect to the cylindrical lateral surface of the first section, wherein at least one set-back region extends to an end of the piston and wherein the first and second sections are arranged on the piston in such a way that in an actuating position of the piston, the main sealing element in the first section of the piston abuts in sealing manner thereagainst and in the pressure equalization position of the piston, in the second section of the piston between the piston and the main sealing element, at least one gap is formed, through which hydraulic medium can flow along the piston from the supply chamber into the cylinder chamber in order to equalize the pressure.

摘要： A hydraulic system comprising a receiving body with electrohydraulic valve, with at least one hydraulic pump, and with channels for connecting the pump to at least one hydraulic load. A pulsation situation arises as a result of the delivery of a pressure medium by the pump and/or as a result of pressure medium being withdrawn by the load. At least one damping unit is provided, having a plurality of pulsation damping means such as, in particular, a damping chamber, and orifice. The hydraulic system provides a uniform and cost-effective solution for different operating situations and prevents a decrease in comfort. The damping unit has at least one switching means for adjusting the action of said damping unit to a varied pulsation situation by connecting or disconnecting one or more damping means.

摘要： The invention relates to a hydrostatic drive comprising a first and a second hydraulic pump (11, 12) and a dual-acting hydraulic cylinder (2). The dual-acting hydraulic cylinder (2) comprises a first working chamber (7) and a second working chamber (8). The first working chamber (7) is defined by a first piston surface (4) of a working piston (3) and the second working chamber (8) is defined by a second piston surface (5) of the working piston (3). The first working chamber (7) is connected to a first connection (13) of the first hydraulic pump (11) and a first connection (14) of the second hydraulic pump (12). The second working chamber (8) is connected to a second connection (16) of the second hydraulic pump (12). A second connection (15) of the first hydraulic pump (11) is connected to a hydraulic fluid reservoir. The ratio of the first piston surface (4) to the second piston surface (5) differs from the ratio of the total delivery volume of the two hydraulic pumps (11, 12) relative to the delivery volume of the second hydraulic pump (12). A tapping valve (45) for removing hydraulic fluid is provided for the volumetric flow equalisation.
