摘要： A hydraulic circuit includes a prime mover that is configured to generate an oscillating flow of hydraulic fluid, and an actuator that is driven by the prime mover and configured to provide oscillating motion and to be connected to a load in each direction of the motion. The hydraulic circuit also includes a reclamation device that is disposed in the hydraulic circuit between the prime mover and the actuator. The reclamation device captures and stores a portion of hydraulic fluid displaced from the actuator during a transition between opposed motions, where the portion of hydraulic fluid corresponds to an amount of hydraulic fluid equal to a volume of fluid required to compensate for compression of fluid within the hydraulic circuit due to system pressure and load pressure. The stored fluid is used by the circuit in a subsequent motion.

摘要： A pumping system deployed in a wellbore has a motor, a pump driven by the motor, and a volumetric compensator connected to the motor to accommodate the expansion and contraction of fluids contained within the motor. The volumetric compensator has a head connected to the motor, a base that includes a fluid exchange port that extends to the wellbore, and a housing extending between the head and the base. The volumetric compensator further includes an inverted bellows assembly contained within the housing. The inverted bellows assembly includes a metal bellows that has an interior, an exterior, a proximal end and a distal end. The interior of the metal bellows is in fluid communication with the wellbore. The inverted bellows assembly may also include one or more guide rings connected to the exterior of the metal bellows. The guide rings are lubricated by the clean motor fluid surrounding the exterior of the metal bellows.

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： 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： 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： A hydraulic system for aircraft operating devices provides a secondary pressure source for direction and deceleration control in case of loss of pressure from a primary pressure source. The system includes multiple pressure accumulators that include a primary accumulator, which supplies pressurized fluid to a first actuator, and first and second secondary accumulators, which supply pressurized fluid to second and third actuators, respectively. If the primary accumulator is disabled, the first secondary accumulator will supply pressurized fluid to the first actuator. If the first secondary accumulator is disabled, the second secondary accumulator will supply pressurized fluid to the second actuator. By providing multiple, substantially independent accumulators, direction and deceleration control is maintained even in the event of loss of the primary accumulator.

摘要： A hydraulic pressure generator having a body (1) with a first bore (11) therein for receiving a cylinder (21) of a piston assembly (2) to define a pressure chamber (12). The cylinder (21) has a second bore (211) for receiving an auxiliary piston (22) which defines a variable volume compensation chamber (23). The compensation chamber encloses a deformable member (5) which is adapted to exert an elastic force between the auxiliary piston (22) and a closed end (210) of cylinder (21). The compensation chamber (23) communicates with the pressure chamber (12) through a restriction (221) formed in a longitudinal duct (222) of the auxiliary piston (22). A sealing member (4) borne by a portion (222) of the auxiliary piston (22) closes the pressure chamber (12) such that the elastomeric member (5) dampens pressure differences between the pressure chamber (12) and compensation chamber (23).
