Abstract: A module cover for a battery module, which has a cell unit with at least one battery cell which includes a releasable vent opening. The module cover has a first region, which is associated with a vent opening region of the cell unit, in which the releasable vent opening of the at least one battery cell is arranged, and at least one second region different from the first region, which is associated with a cell region of the cell unit that is different from the vent opening region of the cell unit. The first region and the at least one second region of the module cover respectively include a plastic material. The at least one second region is formed with a continuous fiber reinforcement embedded in the plastic material and the first region is formed without a continuous fiber reinforcement.

Abstract: A travel sensor for measuring mechanical quantities of motion, in particular for determining the brake pedal position, comprising a transmission unit axially slidable in a housing and comprising a measuring apparatus for generating an electric signal representative of the travel of the transmission unit. The transmission unit is formed of two mechanical transmissions elements (12, 13 and 3, 6, respectively) corresponding with each other and effecting a reduction of the introduced quantity of motions that the test signal is tapped by a reduced test travel. This provides a travel sensor of particularly short dimensions which permits to use of Hall-effect sensors.

Abstract: An anti-lock hydraulic brake system comprising a separating valve (14) and a regulating valve (19). A combined arrangement is provided wherein the valves are connected into each other. The movability (play s) of the piston (30) affords the event that a compensating volume for the control action in the event that the output of the pump is insufficient in specific situations requiring a large amount of fluid for control.

Abstract: A master brake cylinder (2) communicates with wheel brakes through brake conduits (8, 9). Pumps (20, 21) deliver fluid to the brake conduits (8, 9) through pressure conduits (22, 23). Upon commencement of an anti-lock control, the pump drive M is turned on and check valve (26) in the brake conduit is blocked. In conventional systems, the check valve could, during a control operation, open upon an increased pressure fluid requirement of the wheel brakes. Use of a diaphragm in the pressure conduit (22) insures that the dynamic pressure in the chamber (37) will hold the switch piston (28) in all circumstances in a displaced position so that the valve ball (45) blocks the valve passage (46), and the brake conduit (8) is interrupted.
