摘要： A brake actuator for actuating a brake to decelerate a vehicle includes a housing defining a cavity and an integral modulator. An input passage communicates with a source of pressurized air and the modulator. An outlet passage communicates with the cavity and the modulator. The pressurized air passes from the input passage to the cavity via the modulator and the outlet passage. The modulator modulates the pressurized air passed to the cavity.

摘要： A noise reducer for a valve having a quick release function is disclosed. The noise reducer is preferably an open-celled structure that is impervious to dirt, moisture, alcohol, and oil, and acts as both a dampener and a biasing spring to reduce the oscillations of an exhaust diaphragm in an ABS modulator and urge the diaphragm toward a closed position. The open-celled foam is preferably an annular configuration so that it does not interfere with the amplitude of displacement of the diaphragm.

摘要： A control valve device is provided for a pneumatically-operated vehicle brake system equipped with an antilocking device. The control valve has a controlled inlet valve and a controlled outlet valve. A pressure medium outlet chamber may be connected to a pressure medium inlet chamber by the inlet valve and to atmosphere by the outlet valve. The pressure medium inlet chamber is divided into a first sectional chamber connected to the inlet valve and a second sectional chamber connected to the pressure medium inlet. The first sectional chamber and the second sectional chamber can be connected through an additional valve device acting as a check valve which can be moved into an open position in a direction of the first sectional chamber. In this manner, it becomes possible to achieve a pressure reduction by not directing the reflux of the pressure medium from the pressure medium outlet chamber through the pressure medium inlet chamber, but instead through the outlet valve directly to atmosphere. This leads to an accelerated pressure reduction in the pressure medium outlet chamber and thus in the consumer.

摘要： There is provided a wheel lock-up prevention device for compressed air operated brakes of a motor vehicle which includes a common control of the pressure in the brakecylinders of a given wheel axle. The control is accomplished by means of multi-position main valves which include magnetic pre-control valves with identical control magnets and with armatures having integral closure bodies. Furthermore, the valve bodies of the multi-position valves are substantially identical at least on their pressure side. The use of such simple and identical valves provides a modular-like construction making possible a selective 2-point or 3-point operation as well as a single-duct or a multi-duct embodiment of the wheel lock-up prevention device. Thus, during a functional test at the beginning of a trip, a dangerous and hence undesired release of the brakes when parked on an incline is prevented by means of the actuation of all of the magnets.

摘要： A valve unit for controlling air flow and braking pressure in the brake cylinder of a pneumatic braking system. The valve unit has an inlet and an outlet valve assembly each of which are controlled by a solenoid valve, which is in turn controlled by an electronic braking control system. In the inlet valve assembly there is a valve diaphragm which on one side is biased by one pressure to close the valve unit, and which on the opposite side is biased by two pressures to open the valve unit. The ratio between the areas affected by the respective pressures is selected in such a way that the brake cylinder pressure is raised in essentially constant steps.

摘要： In an anti-skid air braking system an air-operated diaphragm valve is arranged to close a connection between the chambers of an air actuator and supply air to the high pressure chamber when the brakes are applied. A flow restrictor delays the release of air from the low pressure chamber when the brakes are released, and the back pressure in the actuator is arranged to act on the diaphragm of the valve to oppose reconnection of the actuator to the supply.
