ABSTRACT:
A pneumatic pressure responsive valve assembly for a pneumatic control system in a vehicle includes a power piston movable due to the pneumatic pressure difference between atmospheric pressure and a signaling vacuum pressure, which piston comprises a valve member cooperable with a valve seat. The valve member is slidably mounted with respect to the power piston. A weak spring disposed between the valve member and the power piston normally seats the valve member on the valve seat and movement of the power piston will unseat the valve member to provide a pneumatic control function.
