Abstract: A pressure container has a steel pipe and an end plate that is formed with a joint portion by allowing its tapered surface to touch a tapered surface of an opening end of the steel pipe so as to block the opening end. The steel pipe has a flange portion which can be cut at the opening end of the steel pipe, and the joint portion is allowed to touch the flange portion. The flange portion is pressed against the opening end along an axial direction so as to touch the end plate, and while the end plate is being pressed against the steel pipe along the axial direction, an electric current is applied so that welding is carried out.

Abstract: A gas chamber (G) and a liquid chamber (R) are separated by a free piston (2) in a cylinder (1) of a hydraulic damper. The free piston (2) comprises a hollow main body (3), a metal bellows (4) which elongates and contracts according to a pressure balance between the gas chamber (G) and liquid chamber (R), and a stopper (8) fixed to the main body (3) for preventing the metal bellows (4) from elongating beyond a predetermined length. By compensating for variation in the capacity of the liquid chamber (R) caused by a displacement of the piston (10) in the cylinder (1) by elongation or contraction of the metal bellows (4), the damping characteristic of the damper is prevented from becoming unstable due to a frictional force acting on the free piston (2). The stopper (8) prevents excessive stress from being exerted on the metal bellows (4).

Abstract: A hydraulic fluid reservoir (10, 10′, 10″, 10′″) comprises a body 12, 12′, 12″ 12′″) defining a variable volume chamber having one end portion movable with the level of fluid in the chamber. A biasing member (18, 18′, 18″, 18′″) acting on a traction rod (16, 16′, 16″, 16′″) extending from the movable end portion restrains movement thereof under fluid pressure. The fluid pressure in the variable volume chamber advantageously counterbalances the force of reaction in the biasing member (18, 18′, 18″, 18′″).

Abstract: The present invention relates to a method and a device for monitoring a brake system for motor vehicles equipped with an electronic controlling and regulating unit, as well as a hydraulic pressure accumulator that is used as an auxiliary pressure source and subdivided by a media-separating element into two chambers, the first chamber being filled with a gas and the second chamber being filled with a liquid pressure medium. To conduct a reliable monitoring of the pressure accumulator, the invention provides that the number of the partial strokes of the media-separating element is detected. To this end, brake actuations are weighted and counted according to their duration and intensity. When the sum of the weighting factors reaches a predetermined number, a warning indicates an imminent damage to the media-separating element. This renders it possible to use a less costly and less sensitive media-separating element, which obviates the need for extensive protective measures against mechanical loads.

Abstract: In an accumulator comprising a pressure vessel, a bellows dividing the interior of the pressure vessel into a gas chamber filled with pressurized gas and a liquid chamber which communicates with a liquid pressure circuit via a liquid introduction port, a stay member attached to the inner surface of the pressure vessel inside the bellows and provided with a communication port for communicating the interior and exterior of the stay member with each other and adapted to be closed by a part of the bellows to define a fully contracted state of the bellows, and a safety valve provided in the stay member, typically in the form of a weakened portion of the stay member, for selectively communicating the exterior of the stay member with the interior of the stay member. Thus, because the safety valve is not provided in the pressure vessel itself, the safety valve of the present invention would not affect the sealing capability of the pressure vessel.
