Abstract: The invention relates to an assembly including a pressure medium reservoir and a manually actuable master cylinder, in particular for a hydraulic motorcycle brake system, wherein the pressure medium reservoir is connected permanently to the master cylinder by at least one pressure medium connection, wherein the master cylinder has at least one pressure chamber, which can be connected to wheel brakes. According to the invention, provision is made for a protection device to be arranged in the region of the pressure medium connection, the device preventing air from penetrating into the pressure chamber and allowing air to escape in the direction of the pressure medium reservoir.

Abstract: A brake system for a motor vehicle which simplifies the hydraulic design and avoids a vacuum prevailing over a relatively long period of time. The first hydraulic unit has a suction volume, which is connected to the suction side of the pump and which, in the event of a change in the pressure on the suction side of the pump, provides a pressure and volume equalization by means of the brake fluid stored in the suction volume, with an elastic element.

Abstract: A pulsation damping capsule including at least one hermetically joint-sealed metal membrane housing made of at least two preferably concave hemispheres, the housing being provided for separating an inner space from a surrounding pressure medium, wherein the hemispheres are connected together along a peripheral seam firmly bonded such that the pulsation damping capsule can be compressed and expanded as an energy accumulator with spring elasticity due to the effect of the pressure medium. A pulsation damping device is provided which is both dimensioned to withstand stresses and is simple to produce, the pulsation damping effect of which can be tailored especially easily to the existing conditions. Further disclosed is a pulsation damping module for housing a plurality of pulsation damping capsules.

Abstract: The invention relates to an electrohydraulic assembly for an electronically controlled brake system with an accommodating member which includes accommodating bores for electrohydraulic valves, accommodating bores for hydraulic supply devices and an accommodating bore for at least one roller bearing, and with hydraulic channels and pressure fluid ports, as well as with an electric motor comprising a rotor with a shaft that is mounted with the roller bearing in the associated accommodating bore in the accommodating member and used to drive the supply devices, and with an electronic control unit being connected to the electric motor by means of a plug penetrating a through-bore in the accommodating member. The objective is to provide a safe and comfortable operating characteristics even in consideration of extreme environmental influences.

Abstract: The present invention relates to a hydraulic aggregate for a hydraulic controlling and/or regulating device, including a pump having a pump housing that includes a leakage chamber with a leakage bore opening into a hollow space of a lid fixed to the pump housing, said hollow space having a pressure-fluid connection to the atmosphere. The leakage bore is connected to the atmosphere by way of a float valve open in its basic position, and the float valve effects closure of the leakage bore under the effect of hydrostatic pressure in lid.

Abstract: The present invention relates to a process of bleeding and filling a slip-controlled hydraulic dual-circuit brake system for automotive vehicles which includes pressure modulation valves and at least one pump, a bleeding device and a filling device, and the bleeding device is connected to at least one bleeder valve of a wheel brake and the filling device is arranged on the braking pressure generator. Bleeding of the wheel brakes is executed in two sequences of operation: in a first sequence of operation, the wheel brakes of the front axle and the rear axle are pre-bled by a cyclic actuation of the braking pressure generator, and in the second sequence of operation the main bleeding and filling of the front-wheel and rear-wheel brakes is executed by actuating cycles of the braking pressure generator, the pressure modulation valves and start of operation of the pump.

Abstract: The present invention relates to a method of bubble-free filling of brake fluid into a hydraulic automotive vehicle brake system, which is equipped with slip control and/or automatic braking intervention, the pump of which, under operating conditions, delivers brake fluid from the secondary circuit into the primary circuit according to the return delivery principle. In this arrangement, exclusively the primary circuit is bled and filled with undersaturated brake fluid.
