摘要:
A hydraulic braking system with slip control, comprising a working piston guided within the brake pressure generator, a booster piston of a hydraulic brake force booster for actuating the working piston at least one wheel brake connected to the brake pressure generator and an electrically excitable auxiliary pressure source adapted to be connected to the brake force booster, a control and regulating electronic unit for detecting the wheel rotating pattern and for controlling the wheel braking pressure by pressure modulating valves. An electronic sensor is provided for detecting the relative movement between the pressure rod and the booster piston, the output signals of which are capable to influence the excitation of the auxiliary pressure source. This will permit the brake force boosting, if need be, to be effected independently of actuation forces put in manually, with anti-locking control/traction slip control functions being readily exercisable at any time.

A method for controlling a brake system for automotive vehicles including a vehicle speed control unit permitting the adjustment of a predetermined vehicle speed by way of an automatic intervention into brake control, wherein upon a braking request of the vehicle speed control unit and, simultaneously, a braking request of the driver the function of the vehicle speed control unit is deactivated, wherein the pressure (Px) introduced into the wheel brake due to the braking request of the vehicle speed control unit is reduced according to a predetermined function upon the braking request of the driver, wherein preferably a resulting brake pressure (Pres) is adjusted in the wheel brake of the vehicle which is determined by the formula Pres=PF+PX[1]−(PF*PX[1])/constant Z.

摘要:
The setpoint generator according to the invention utilizes the information "pedal travel s" in combination with the information "pedal force p" by weighting them in input circuits 4,5 and summing up the corresponding partial setpoints p'.sub.s and p'.sub.p to form a setpoint p'.sub.Hz. Here, a countercurrent weighting takes place: If a small force acts on the pedal, the pedal travel is dominant; as the pedal force is growing, the latter is weighted more heavily. In this way, a smooth brake behavior is attained, whereby the comfort is enhanced and the wear of the employed components is reduced.

A method for the hydrodechlorination of a reaction gas primarily composed of chlorinated hydrocarbons is carried out sequentially. A first step is advantageously carried out in a tubular reactor filled with catalyst and cooled externally, to maintain a temperature within a preferred range of 80.degree. to 230.degree. C. and a radial temperature difference of not more than 40.degree. C. Hydrogen is added to the tubular reactor with a hydrogen excess in a preferred range of 1.1 to 1.5 relative to the reaction gas, based on the stoichiometric consumption. The catalyst is present in a catalyst loading in a preferred range of 0.1 to 1.5 v/vh based on the volume of reaction gas. A fixed bed reactor is advantageously used for a second step, optimally connected in straight transit with the output of the reactor of the first step. The full-space reactor is maintained at a temperature within a preferred range of 200.degree. to 300.degree. C. and a hydrogen excess relative to the stoichiometric consumption is in a preferred range of 2 to 100. Catalyst is present in a preferred amount related to a volume of catalyst in step one according to a ratio in a range of 2:1 to 10:1. The dechlorination is preferably carried out at pressures between 1 and 50 bar. A method is further provided for regenerating deactivated catalysts without accumulation of dioxin in the waste gas, achieved by a reducing treatment, followed by an oxidizing treatment at a temperature at or above the last operating temperature of the catalyst.

A hydraulic motor vehicle brake installation, the braking pressure modulation of which occurs over adjustable wing cell pumps, as space-saving solution it is proposed to have all the required wing cell pumps driven over a common shaft by a turning-rate stabilized electric motor. An individual control of each individual wing cell pump occurs through the drive of a lift ring each by one proportional magnet per wing cell pump.

摘要:
A pressure control valve has a valve-closing member displaceable relative to the valve lifter in order to control the flow of pressurized medium between a first and second pressurized medium connection. A third pressurized medium connection is severed from the second pressurized medium connection by another valve-closing member that can be actuated by the valve lifter.
