Abstract
837,052. Pressure-regulating valves. WESTINGHOUSE AIR BRAKE CO. Dec. 16, 1957 [Dec. 28, 1956], No. 39025/57. Class 135. In a self-lapping pressure-regulating valve the delivery pressure acting on the upper surface of a fixed-area diaphragm 9 is balanced by the supply pressure acting, through a passage 39, on the underside of a second diaphragm 12 of variable effective area, the variation in area being effected by downward movement of a plunger 5 to progressively disengage the upper surface of the diaphragm 12 from a conical seating 14 formed in the valve casing. Supply and pressure-release valves 2, 3 are connected by a stem 23 and engage seatings formed in an operating plunger 4 and plunger 5. Upon depressing plunger 4, valve 2 is unseated to allow pressure fluid to pass from inlet port 7 to delivery port 6 and, through a passage 40, to act upon diaphragm 9 and thus depress plunger 5 and unseat the central portion of diaphragm 12, the valves 2, 3 being reseated when equilibrium is established. Progressive operation of plunger 4 results in a larger area of diaphragm 12 being exposed to the supply pressure, thereby increasing the delivery pressure. Valve 3 governs venting through an atmospheric port 8, and downward movement of plunger 5 carries a flange 33 clear of an opening 34 in the diaphragm seating 14 to ensure that the upper surface of diaphragm 12 is subjected to atmospheric pressure through port 8.
