Abstract

1,043,806. Valves. BENDIX-WESTING- HOUSE AUTOMOTIVE AIR BRAKE CO. March 20, 1964 [March 26, 1963], No. 11963/64. Heading F2V. [Also in Division G3] A valve suitable for insertion in the line between a compressor and a receiver comprises an inlet chamber 12, a delivery chamber 14 and a check valve 60 allowing flow from the inlet to the delivery chamber. The check valve forms part of a piston 46 slidable in bore 47 and co-operating with a stop 48 carried by a spindle 42. The latter also carries an exhaust valve 36 loaded by a spring 54. When the pressure in the inlet chamber reaches a predetermined value it unseats the exhaust valve with a snap-action and the lowered pressure in the inlet chamber then allows the piston 60 to be driven downwardly by the receiver pressure until it engages stop 48, whereby the exhaust valve is retained open until the receiver pressure drops to a second, lower, predetermined value. In modifications, the piston and exhaust valve are rigidly interconnected, or the spindle 42 is rigid with the piston and the exhaust valve is slidable on the spindle with its loading spring in exhaust chamber 35. A filter may be provided in the inlet chamber upstream of the check valve. The latter comprises an annular gasket supported on a plate 64 retained by a snap-ring 66.
