Abstract: A pressure accumulator includes a housing having a housing cavity, a piston axially displaceable in the housing cavity between a first final position and a second final position and having a pressure surface which together with a wall of the housing cavity delimits at least partially a reservoir connectable to an ICE consumer in a fluid-conveying manner, an energy store cooperating with the piston, the piston being displaceable against the force of the energy store from the first final position into the second final position in that the reservoir is acted on by pressure using a pressure medium, and a locking device for locking the piston in the second final position. A locking tube is connected to the piston and supported within the housing in an axially shiftable manner, and lockable at an end of the housing facing away from the reservoir with the aid of a locking pin.

Abstract: A lightweight, optimally efficient, easily serviced, piston-in-sleeve high pressure accumulator is provided. The accumulator includes one or more cylindrical composite pressure vessel separate end cap manifolds. A piston slidably disposed in a thin impermeable internal sleeve in the accumulator separates two chambers, one adapted for containing a working fluid and the other adapted for containing gas under pressure. Gas is provided in a volume between the impermeable internal sleeve and the composite pressure vessel wall. Additional gas is optionally provided in gas cylinders. Further components are provided for withstanding harmful effects of radial flexing of the composite vessel wall under high pressures, and from stresses present in use in mobile applications such as with a hydraulic power system for a hydraulic hybrid motor vehicle.

Abstract: A hydraulic pulsation damper system for installation into an otherwise rigid hydraulic system to absorb and extinguish pressure pulsations being transmitted through the system by hydraulic fluid contained therein. The system is useful in suppressing pulsations in automotive fuel lines supplying fuel to fuel injection systems. The system includes fuel-conducting tubing made of flexible, non-permeable material that includes a convoluted central portion capable of expanding and contracting in response to pulsations in the fuel. Resilient foam is molded around the convoluted portion for controlling expansion of the convolutions. The foam and convoluted tubing are contained within a housing made from a larger-diameter hose having ends sealed as by swaged connectors. The damper system may be bent to accommodate installation with a fuel line in an engine and can conveniently provide a sound-deadening link in the fuel line of a vehicle between a body-mounted portion and an engine-mounted portion thereof.

Abstract: A tank formed using two half shells may be used as an expansion tank, expansion equalizer, pressurized fluid buffer tank or the like. Two half shells are provided with a projecting flared profile having a first section angled outwardly from the wall and a flange directed perpendicularly outwardly. The tank halves are joined by abutting the flanges, and the angularly offset sections adjacent the flanges form a bearing area or seat for sealing with an internal diaphragm. The diaphragm separates the tank into sections and is arranged at its end to receive and positively hold a ring of a profile complementary to the internal profile defined by the outwardly flaring sections adjacent the flanges of the tank. The flanges can be folded over one another and against the wall of the tank to physically attach the half shells.

Abstract: The diaphragm of the invention is for expansion tanks comprising a pair of shell halves and is for interposition between such shell halves to seal the joint between the shell halves and to anchor the diaphragm so as to divide the tank into a pair of chambers. The diaphragm includes a central sheet of elastomeric material terminating in a peripheral edge that includes an outer peripherally extending column integral with the central sheet and having a pair of integral flange elements and a central web element extending inwardly therefrom. Each of the flange elements is spaced from the central web element to form an annular slot therewith. The slots are dimensioned so as to releasably and sealingly receive the respective skirts of the shell halves.
