Abstract: In a hydropneumatic accumulator, the gas volume contained therein is monitored by measuring the volume increase in the hydraulic fluid, which takes place during a pressure increase at a given minimum pressure. Moreover, for monitoring purposes, the hydraulic pressure is measured and a signal transmitted at insufficient gas volume as a function of the volume increase and the pressure increase. In order to obtain reliable signals concerning the filling state of the accumulator at all ambient operating temperatures, the temperature of the environment and the gas volume is detected, a standard value for the volume increase proportional to the ratio of the gas temperature to the minimum pressure determined and the volume increase causing the pressure increase compared to this standard value.

Abstract: A pulsation absorbing device and method of making a pulsation absorbing device is disclosed. The pulsation absorbing device includes a pressure vessel having a resilient diaphragm mounted therein together with an inlet associated with one end of the pressure vessel and an outlet associated with the other end of the pressure vessel. A spool is mounted within the pressure vessel inwardly of the resilient diaphragm and intermediate and in communication with the inlet and the outlet to carry fluid from the inlet to the outlet. The spool and the resilient diaphragm define a pressure chamber therebetween which is in fluid communication with fluid carried from the inlet to the outlet through holes in the spool. A helical wave band is disposed on the spool for accommodating flow through the holes in the spool and defines a plurality of helically spaced flow accommodating openings. With this arrangement, at least some of the flow accommodating openings of the helical wave band are in communication with the holes in the spool after the helical wave band has been spirally wound upon the spool in accordance with the disclosed method.

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 protective device for employing in an accumulator wherein, in a pressure vessel, a separating member dividing the interior of the pressure vessel and a supporting cylinder having open pores as said protective device are coaxially arranged in order of approaching the axis. The protective device is for protecting the separating member from damage when the separating member is pressed against the supporting cylinder. By virtue of employing the novel protective device in an accumulator, the fluid flow through the supporting cylinder is not hindered and no fragments detached from the material of supporting cylinder enter the fluid to damage the fluid system.

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.
