    • The invention relates to a hydraulic fluid accumulator comprising a housing (1), whose interior is subdivided into three chambers (2, 3, 4), whereby the first chamber (2) is filled with a gas and separated from the second chamber (3) by a first media separation element (6). Said second chamber is filled with a liquid and is separated from the third chamber (4), which is also filled with a liquid and is connected to a hydraulic line (5), by a second media separation element (7). To guarantee an effective separation of the media within the hydraulic fluid accumulator and thus a significant increase in its functional safety, the invention is characterized in that the second media separation element (7) is embodied by a metal piston (8, 80) which delimits a space that can be deaerated (9, 90) in the housing (1).

    • The invention relates to a piston-type accumulator designed notably for hydraulically actuating the discharge unit in non-automotive bulk commodity vehicles. In said accumulator the cylinder (1) comprises a tappet (25) which can be axially displaced within the cylinder and when a defined load pressure is reached in the oil chamber (5) of the cylinder (1) can be displaced by the piston (3) so as to actuate a control valve (23). The valve serves as shut-off device for the loading fluid stream flowing to the oil chamber (5) and is positioned as a detachable module on the exterior face of the cylinder cover (39) in such a way that it can be actuated by the outer end of the tappet (25) which is guided towards the outside by passing in a sealed manner through the cylinder cover (39).

    • An accumulator piston (10) for an automatic transmission (12). The piston (10) comprises two components, the first and second being cup elements (32 and 36) welded together with their closed ends in abutting relation. The lower cup (32) includes a curled back portion with a radial flange having an axially extending bi-directional oil seal (34) thereon, and spaced apart recesses in the curled back portion to permit oil to flow therein. The upper cup (36) includes a radial flange of reduced diameter compared to the lower cup flange. The flange also has a lip seal (40) thereon. The piston (10) is spring-loaded and moves up and down in a pair of opposed bores (46 and 72) in response to fluid flow on either side to absorb shifting shocks.

    • The invention relates to the compact construction unit of a hydraulic unit, especially for a slip-controlled braking system. A pump (17, 18, 19), electromagnetically actuated valves and at least one low-pressure storage unit (24) are arranged inside a valve block (1). The valve actuators are situated opposite an electric motor driving the pump (17, 18, 19) and in front of a base (29) of the valve block (1). The housing of the low-pressure storage unit is embodied as an add-on piece (30) made of a metal sheet drawn in a cup-shaped manner. The edge of the add-on piece (60) is fastened in the mouth of a blind hole (32) in the valve block (1). Said add-on piece (30) extends above the base (29) and has about the same height as the valve actuators (23). The actuators and add-on pieces (30) are covered by a housing cap (75) on the valve block which cap protects them against environmental influences. This arrangement is very compact and allows for the construction of a relatively small and thus light valve block (1).
