Title: Brake valve with pilot piston - has throttled pilot valve loading main valve plug against spring pressure
Inventor: ZICK JUERGEN DR ING
IPC: F15B13/01
Filed: 1976-01-27
Abstract: The brake valve is controlled by pressure signals from a moving differential cylinder or from the inlet pressure of a hydraulic motor. The signal which operates the valve acts on a piston (15) in chamber (9) and thus on the valve seat (8). Oil enters the valve via the opposite end (10) and passes through the throttle (7) into the anticipatory control chambers (11) connected with each other. If there is no signal pressure (9), the oil in the anticipatory control chambers lifts the plug off the valve (8) and leaves the valve via a side connection (14) to the tank. There is no pilot control pressure large enough to shift the main control valve (3). Therefore no oil is admitted from the working connection (12) to the tank connection (14) or the low pressure side (13) of the valve. If there is a signal (9) the valve (8) is pressed against its seat, pilot control pressure builds up in the chamber (11), which shifts the main control valve /3/ against the force of a spring (4), and oil flows (12) to the main tank connection (13).
