    摘要： The invention relates to a structural component in the form of a parting element (10) which extends in two different main directions (12,13), is of at least single-layer design and is elastically flexible, which parting element (10) has at least two linear structural parts (18) which are arranged offset with respect to one another in the two main directions (12,13). As a result of at least a part of the linear structural parts (18) having a loop-shaped cross section and as a result of the parting element (10) being formed at least partially from a substance which has a fluoroplastic material, preferably a substance composed entirely of fluoroplastic material, a structural component is obtained which is characterized not only by excellent diffusion impermeability but also by particularly good mechanical properties such as extreme bending fatigue strength.

    摘要： A hydraulic accumulator with an accumulator housing (1), in the interior of which a metal bellows (3) is arranged, the metal bellows having a plurality of membrane discs (17, 19), the edges of which are alternately connected to one another by weld seams (21, 23), and the metal bellows forming a movable separating element between a gas side and a fluid side, the volumes of which are changeable by means of extension and compression of the metal bellows (3) taking place in the axial direction. The hydraulic accumulator is characterized in that, in at least some of the membrane discs (17, 19), the weld seams (21, 23) are dimensioned in such a manner that the thickness of the weld seams (21, 23), as measured in the direction of the thickness of the membrane discs (17, 19), is at most the same as the entire thickness of the membrane discs (17 and 19) to be welded together.

    摘要： A hydraulic energy accumulator consisting of a housing with a space for inserting metal bellows, comprising a non-moveable end and a moveable end with a front wall arranged in a sealed manner on the bellows and separating a hydraulic pressure medium from a pressurized gas is already known per se. The advantage of using metal bellows is that they are gas-tight in so far as no leak arises over time. According to the invention, the bellows are embodied in such a way that the pressure of said bellows in the gas is reduced in comparison with the hydraulic medium as a result of the longitudinal elasticity of said bellows and a sensor system (6) is provided which indicates a longitudinal expansion of the bellows (5) when the hydraulic pressure medium flows through a leak in said bellows into the area containing the gas. The inventive hydraulic energy accumulator (2) and the sensor system (6) thereof are also capable of indicating when such a leak occurs in the bellows. The indication of a leak is also an indication that a motor vehicle braking system fitted therewith has become unsafe.
