Automatic water venting valve for pressure line - has inertial mass to tilt valve on braking acceleration

摘要

The valve to clear water from air pressure lines in vehicles is held in a vertical setting by a central spring and with an inertial mass (17) at the lower end of the valve stem. When the vehicle accelerates or brakes the mass displaces the valve and vents for a set period. The valve and spring are set so that normal travel does not open the valve, only the strong braking and acceleration forces. The valve is set in the lowest part of the pneumatic system and can also be operated by hand.
