    Abstract: The invention relates to a pressure accumulator which may be used in an electronically controllable vehicle braking system for a motor vehicle. In an electronically controllable vehicle braking system with a cylinder/piston arrangement (i.e., a master cylinder) providing a brake fluid , a brake pedal actuates the cylinder/piston arrangement to provide brake fluid acting on the brake of the motor vehicle. The cylinder/piston arrangement is connectable with a pump arrangement and the pressure accumulator.

    Abstract: A hydraulic accumulator comprises two-halfs shells, the diaphragm therebetween defining two cavities. One cavity contains presssurized gas and the cavity receives hydraulic fluid under pressure. The two-half shells are held together by a mechanical element, such as a belt which has been previously prestressed to a tension selected according to the maximum pressure to which the accumulator will be subjected. The use of the prestressed mechanical element changes the dynamic stresses ordinarily found in a hydraulic accumulator to static stresses, thus minimizing the occurrence of creeks and failure of the device.

    Abstract: The pressure vessel of a hydraulic accumulator comprises bowl-shaped body and lid members welded together edge to edge, lid member uppermost. A bowl-shaped diaphragm in the vessel having its concave surface facing up is supported by a rigid ring having a large diameter radially outer portion seated on an upwardly facing circumferential shoulder on the body member, near its rim. A smaller diameter radially inner portion of the ring is clinched over a bead around the edge of the diaphragm. The ring also has a frustoconical, upwardly tapering radially intermediate portion connecting its radially inner and outer portions, to hold the rim of the diaphragm at a high level in the vessel.

    Abstract: A hydraulic actuating device for a coupling device having an actuating piston, a piston chamber assigned to the actuating piston and a supply chamber which is arranged further inwards in the radial direction than the piston chamber and via which a hydraulic fluid can be supplied to the piston chamber, wherein the supply chamber is delimited in a first axial direction by a first housing part and in a second axial direction opposite to the first axial direction by a second housing part, and the first housing part is fastened to a hub. The first housing part is fastened to the hub by clamping the second housing part in the axial direction between the first housing part and the hub. Furthermore, the present invention relates to a coupling device having such an actuating device as well as a method for manufacturing such an actuating device.
