    摘要： A hydraulic drive system for driving a load includes a drive shaft; first and second hydraulic pumps driven by the drive shaft, and a control system that operates the hydraulic drive system in a plurality of modes including: a) a first mode where the second hydraulic pump pumps hydraulic fluid from a supply line to an accumulator; b) a second mode where the second hydraulic pump pumps hydraulic fluid from the accumulator to the supply line; c) a third mode where the second hydraulic pump pumps hydraulic fluid from the supply line to a reservoir; and d) a fourth mode where the second hydraulic pump pumps hydraulic fluid from the reservoir to the supply line. At least the second hydraulic pump is a variable displacement bidirectional pump.

    摘要： Disclosed is an expansion tank having an internal cavity separated by a flexible diaphragm to form an upper pressurized gas portion and a lower pressurized fluid portion, and an indicator positioned at an upper part of the expansion tank in communication with the contents of the upper pressurized gas portion. The indicator is configured so as to display a first color if the operating conditions are normal in the pressurized gas portion, and a second color if the amount of moisture detected in the pressurized gas portion greater than or equal to a predetermined amount. Further disclosed is a method for detecting whether there is an excessive amount of moisture in a pressurized gas portion of an expansion tank by allowing pressurized gas from the pressurized gas portion to come into contact with the indicator, and viewing the color displayed by the indicator. As such, the tank can be simply visually inspected to determine whether there is a potential failure in the tank.

    摘要： An accumulator (10) for a fluid system comprises a pressure vessel (12) with a baffle (16) oriented at a skew angle (θ). The baffle (16) divides the vessel (12) into first and second volumes (V1, V2). A first port (28) is provided to introduce a pressurizing fluid (14) into the first volume (V1), and a second port (32) is provided to circulate a working fluid (15) within the second volume (V2). A purge aperture (20) is provided to purge the pressurizing fluid (14) from the second volume (V2) across the baffle (16) into the first volume (V1), and a flow aperture (22) is provided to transfer the working fluid (15) through the baffle (16) between the first and second volumes (V1, V2).

    摘要： A pressure accumulator comprises an accumulator housing (2) in which a movable separating element (30) fluid-tightly separates a gas chamber (16) filled with a working gas from a fluid chamber (28). The pressure accumulator is characterized in that a monitoring device (50, 54) is provided which supplies an optical signal in the event of a malfunction affecting the sealing effect of the separating element (30).
