    Abstract: A hydraulic actuator (20) with a built-in hydrostatic pressure compensator (111) is provided. The actuator (20) includes an actuator housing (30), a compensator cylinder portion (86), a compensator piston portion (94), a first compensator piston chamber (98), a second compensator piston chamber (103), a hydraulic port (106), and a hydraulic via (108). The compensator cylinder portion (86) is located within the actuator housing (30), is fixed relative to the housing (30), and has a compensator cylinder internal chamber (88) formed therein. The compensator piston portion (94) slidably fits within the compensator cylinder internal chamber (88). The first compensator piston chamber (98) is formed between a first side (101) of the compensator piston portion (94) and the compensator cylinder portion (86). The second compensator piston chamber (103) is formed between a second side (102) of the compensator piston portion (94) and the compensator cylinder portion (86). The hydraulic port (106) is routed through the housing (30) and opens to the first compensator piston chamber (98). The hydraulic via (108) fluidly couples the second compensator piston chamber (103) with a first housing internal chamber (82).

    Abstract: An energy storage device comprising a high pressure liquid accumulator, a low pressure liquid accumulator and at least one pump and motor unit, i.e. a device able to be used as a pump and a motor which is connected to a means, such as the drive train of a vehicle, supplying or absorbing energy as the case may demand and during charging of the high pressure liquid accumulator from the low pressure accumulator functions as a pump and on discharge thereof functions as a motor, at least that pressure line connecting the high pressure accumulator and the pump and motor unit having a shut off valve therein. A piston delimiting the storage space of the low pressure liquid accumulator is connected to a telescoping cylinder bearing against the end plate of the accumulator and the cylinder is connected via an operating pressure line with the high pressure accumulator for pressurization. On charging of the high pressure accumulator with an accompanying discharge of the low pressure accumulator it is thus possible to avoid a fall in the pressure in the latter to an overly low level; in fact the pressure fluctuates about an average value between a relatively high minimum value and a maximum value. The latter feature is due to the changing size of the active pressure faces as the telescoping pressure cylinder is extended one part after another.

    Abstract: In an actuator (102), a piston head portion (108) reciprocates in a large diameter section of a cylinder casing (102), dividing such section into first and second variable volume chambers (112, 116). An end portion (104) projects outwardly of the cylinder casing (102) and includes a mounting (162) at its end. The opposite end portion (106) extends into a third variable volume chamber (120). A piston head portion (82) reciprocates in a piston section (72) of a volumetric compensator (14). One end portion of piston (80) is slidably received within first variable volume chamber (90). The opposite end portion (86) of the piston (80) extends through a central opening in a diverter wall (88) between the piston section (72) and a gas charge section (78). Pressurized gas within the gas charge section (78) acts on the second end (86) of the piston (80), forcing hydraulic fluid in chamber (90) to chamber (120 ) of actuator (102). The gas pressure in chamber (116) and the hydraulic fluid pressure in chamber (120) both exert a force between the actuator piston and cylinder casing tending to extend or elongate the actuator (102). Variable volume chamber (100) of the compensator (14) and variable volume chamber (112) of the actuator are interconnected and fluid is transferred back and forth between them during movements of the compensator and actuator pistons.

    Abstract: A volume control device for a sealed reservoir for storing oil under pressure and which supplies oil to a power circuit. The volume control device has an expansible bellows assembly which contracts upon a predetermined increase of volume of oil in the reservoir to bring a rod into engagement with a ball check valve and unseat the valve for dumping of oil overboard from the reservoir. The dumping of excess oil from the reservoir is controlled by an increase of volume of oil in the reservoir, rather than an increase in oil pressure.
