    Abstract: A reciprocating piston pump having a housing, pistons disposed opposite one another in the housing, an eccentric between the pistons, annular grooves that fit around the piston necks machined into piston ends oriented toward the eccentric, and a U-shaped hoop spring curved radially outside the eccentric in the circumferential direction thereof. The hoop spring includes forklike hoop spring ends which engage the annular grooves and press the piston ends toward the eccentric. In the circumferential direction of the substantially U-shaped hoop spring, a continuation is formed on the hoop spring and together with a stop disk aligned transversely to the eccentric shaft, forms a device that limits the pivotability of the hoop spring about the piston necks. The reciprocating piston pump is usable for instance in hydraulic motor vehicle brake systems and in other hydraulic equipment.

    Abstract: A brake booster for a pressure-fluid-actuated, and in particular hydraulic, brake system equipped with both ABS and traction control has a servo piston that is controllable by a brake pedal, and an additional piston that is controllable via a magnetic valve assembly in traction control operation; to control a brake pressure in the brake system, both pistons act via a pressure rod upon the brake piston of a master brake cylinder. For the sake of a short structural length of the brake booster, the additional piston is embodied as an annular piston, which coaxially surrounds the pressure rod and is sealed off from it, and which rests on a radially protruding driver element of the pressure rod in order to displace it.

    Abstract: A brake booster in which a servo piston is slidably supported in a housing. The transmission of a brake force is effected via a piston rod protruding into the housing, and a work chamber is formed between the piston rod and the servo piston. After the opening of a valve, this work chamber can be filled with brake fluid from a reservoir or supply container via a pump or the like. A return line also leads out of the work chamber back to the supply container, via a further valve. To improve the closing or sealing behavior of the valves, the first valve is to be embodied for admitting the brake fluid from a valve cone, or its shoulder, the valve cone extending axially in a blind bore of the servo piston, and a valve seat formed out of a valve bushing. The second valve is likewise embodied as a seat valve, and an element connected with the valve cone cooperates with an element connected with the piston rod.

    Abstract: A brake booster having a brake valve disposed inside a booster piston, the brake valve comprises a valve bushing including a valve seat and a slide that is pressed by a spring against the valve seat of the valve bushing. The slide is supported with play at a great distance from the valve seat, so that it can be pivoted slightly around the vicinity of its bearing. The pivotability of the slide facilitates its centering in the valve seat, so that the valve closes dependably even in the presence of bearing tolerances or valve seat tolerances. Seals required for sealing off the slide have an elastic behavior, and are disposed in the vicinity of the bearing. As a result, reliable sealing is assured despite the pivotability of the slide.
