Abstract: A hydraulic motorcycle braking system is disclosed. In the hydraulic motorcycle braking system a pump suction valve, which is situated in a braking circuit that does not contain an isolating valve or a change-over valve, has a higher opening pressure than a pump suction valve which is situated in a braking circuit provided with an isolating valve and a change-over valve. Accordingly, pressure oscillations initiated during the start-up of the pump cannot have a retroactive effect or only have a slight retroactive effect on the actuated brake master cylinder.

Abstract: The present invention related to a piston pump, in particular for controllable brake systems such as ABS or ESP, wherein a working chamber of the pump in front of a piston is delimited by a pressure valve, and a resetting spring with its one end is supported on a valve seat carrier of the pressure valve and with its other end resets said piston into its bottom dead center position. An object is to render the assembly of the mass-produced pumps as inexpensive and simple as possible. To achieve this object, the present invention discloses that the resetting spring be adapted to be attached directly or indirectly to the valve seat carrier in addition.

Abstract: The present invention discloses a hydraulic fluid accumulator comprising a housing having an interior subdivided into three chambers, with the first chamber being filled with a gas and separated from the second chamber by a first media separation element, the second chamber being filled with a fluid and separated by a second media separation element from the third chamber that is also filled with a fluid and connected to a hydraulic port. To safeguard an effective separation of media within the hydraulic fluid accumulator and, thus, a significant increase in its functional safety, the present invention arranges for the second media separation element to be embodied by a metal piston delimiting a chamber that can be vented in the housing.

Abstract: This invention relates to a device for the generation of auxiliary pressure, and has control valves (2) arranged in a control housing (1) of a control unit. The control valves (2), depending on their position, actuate several control channels (4) leading into severan control pressure chambers (3) so that, depending on the position of the control valves (2), communication can be established between an energy source (5) and s spring-loaded servo piston (6) which, via an adjoining working cylinder (7) sealed by the servo piston (6), delivers a medium of low pressure level to an energy level of high pressure by means of a pressure piston (8), with the servo piston (6) having elastic means (11) which influences a change-over point of the control valves (2) and which, for the purpose of switching the control valves (2), can be clamped in position between a servo element (9) connected on the servo piston (6) and control rod (10) engaging the control unit.

Abstract: A valve block for a slip-controlled hydraulic brake system, comprising valve domes (10) incorporating magnet coils (7), having insulating casings (6) cast around the magnet coils (7). A conducting-path housing (1) containing several conducting paths (2) are provided wherein the magnet coils (7) are electrically connected to the conducting paths (2) by means of spring contacts (9). To avoid soldering of coil and conducting paths as well as the catch-type securement of the housing cover, an elastic spring contact is fastened between magnet coil and coil jacket which, instead of a soldered joint, provides the electrical connection to the conducting path. The arrangement obviates the need for the complicated mounting of a separate housing cover, since due to the construction and jointing method component parts of the valve block are encapsulated by the external housings.

Abstract: A device for the generation of auxiliary pressure for slip-controlled brake systems with a pedal-force-operated brake booster connected to a tandem master cylinder (19). A pressure is transmittable in the brake booster housing (7) of the brake booster to the wheel brakes connected downstream. This pressure is controlled by an electromagnetically operated control valve (5) in that the pressure as a hydraulic pressure is influenced by the pneumatic actuation of a servo piston (2). The servo piston (2) is fastened on an auxiliary pressure control piston (1) within the brake booster housing (7) and the influence is a function of thermodynamic state variables of different energy sources (11). Thus, a device is provided for the generation of auxiliary pressure which, while using simple constructional configuration, provides an operationally reliable and economical use of available thermodynamic state variables such as the atmospheric pressure and of the gas throttling of an internal combustion engine.
