Automatic braking pressure regulation valve for automobile braking system has setting piston cooperating with control rod of regulation part for switching between dynamic and static operation

摘要

The braking pressure regulation valve (1) is pneumatically controlled, with a spring-loaded setting piston acted on by a pressure which is dependent on the loading, an angled control face (38) of the setting piston controlling a control rod (11) for the regulating part of the braking pressure regulation valve, which is switched between dynamic and static operation. A pressure-operated blocking piston (15), cooperating with a resetting spring (16), is used for fixing the setting piston via a friction coupling between cooperating piston surfaces (23,35).
