    摘要： In a machine press with a lower and an upper tool support, a closed hydraulic drive system acts upon the upper tool support. This system has at least one hydraulic drive unit (1), which for its part comprises at least one hydraulic cylinder-piston unit (2) and at least one hydraulic assembly (6) acting upon this unit and supplied from a storage reservoir (20). A base pressure above environmental pressure constantly prevails in the storage reservoir. The storage reservoir (20) is designed as a cylinder store (22) with a hydraulic chamber (21) defined by a cylinder (23) and a piston unit (24) displaceably guided therein. The piston unit is acted upon on its side functionally opposite the hydraulic chamber by a hydraulic fluid chamber (25) which for its part is connected to a high-pressure gas store (26). The active surface (27) of the hydraulic fluid chamber (25) on the piston unit is small compared to the active surface (28) of the hydraulic chamber (21) on the piston unit (24).

    摘要： An expandable accumulator and reservoir assembly includes a housing defining an interior chamber configured to contain a working fluid therein. An expandable accumulator is positioned at least partially within the housing. The expandable accumulator includes at least one flexible member configured to be at least partially immersed in the working fluid contained within the interior chamber. A rigid support member is positioned in the interior chamber and outside of the expandable accumulator. The rigid support member has at least one aperture to allow passage of the working fluid. An additional flexible member is positioned outside the rigid support member and has perimeter portions sealed to the outside of the rigid support member. The additional flexible member defines a flexible boundary between a primary reservoir inside the additional flexible member and a separate secondary reservoir outside the additional flexible member.

    摘要： A reservoir (26) includes first and second chambers (38, 36), and a piston (42) having first and second ends (48, 44) disposed in the first and second chambers (38, 36), respectively. The first and second ends (48, 44) isolate a first area (52, 112) from a second area (50, 46) within the first and second chambers (38, 36). The first area (52) of the first chamber (38) is in fluid communication with a high pressure fluid source and the second area (50) of the first chamber (38) is in fluid communication with a low pressure fluid source. An orifice (56) is formed in the first end (48) and is configured to allow fluid communication between the first and second areas (52, 50) of the first chamber (38). A pumping system (10) and an aircraft are also disclosed.

    摘要： A stand pipe is disposed so as to be fitted with the inner periphery surface of a piston rod with a hollow structure and a reservoir is incorporated into the inside of the stand pipe, whereby it becomes possible to reduce the size of an EHA device. Besides, since the reservoir is separated from both an annulus-side oil chamber and a bore-side oil chamber, a stable reservoir performance can be exhibited without being influenced by a fluid pressure resulting from an external force. Moreover, as a result of installation of the stand pipe, a difference between the amount of fluid required per unit stroke in the annulus-side oil chamber and that in the bore-side oil chamber becomes smaller, so that the required volume of the reservoir oil chamber can be reduced and it is possible to constitute an efficient EHA device with little difference between the energy consumption during compressing and that during extending. Consequently, it is possible to provide a reservoir built-in type actuator capable of exhibiting a stable performance without being influenced by an external force acting on the actuator and capable of attaining the reduction in size of the entire EHA device.
