Vacuum braking power intensifier for motor vehicle with intensifier housing - having inner compartment subdivided by movable partition into vacuum and working chambers and control housing carrying moving portion with control valve

摘要

The control valve (12) is operated by a solenoid (20), independently of an operating rod (7) moving a valve piston (9), which operates a third sealing seat (24), which facilitates the venting of the working chamber (3). So that the separate power to be applied by the solenoid (20), is kept as small as possible, the solenoid (20) is arranged securely fixed to the valve piston (9), movable in the control housing (5), so that the third sealing seat (24) is movable synchronously with the valve piston (9). ADVANTAGE - Makes possible large redn. of separate power applied from solenoid.
