Abstract

915,760. Valves. WESTINGHOUSE AIR BRAKE CO. July 18, 1961 [Aug. 9, 1960], No. 25952/61. Class 135. A fluid-flow control valve comprising a closure member 12 actuated by a plunger 14, the latter being operated by a cam 33 removably mounted on a rotatable shaft 28 and having a number of cam surfaces 34, 35, 36, the cam being so positionable on the shaft that only one of the cam surfaces at a time is effective for operative engagement with the plunger, and detent means comprising a disc 32 removably mounted on the shaft and having a number of notches 38 engageable by a pawl 39 so as to selectively determine the angular position of the shaft, the cam and disc being each angularly positionable on the shaft in any one of a number of different positions relative to the shaft and each other, whereby variations in characteristics of the operation of the closure member may be effected. The closure member 12 controls communication between an inlet 10 in the valve body 2 and an outlet 21, the latter, with the valve in the position shown, normally being in communication with the atmosphere via an annular space 4, ports 22, bore 15, and ports 24 in the plunger 14; a sintered metal filter 9 is provided in the inlet 10. The cam 33 and disc 32 are secured on splines 31 formed on the spindle 28. A handle 42 is removably secured to the shaft 7 and is provided with stop means in the form of a pin-and-slot device 46, 47. Additional stops are formed in the handle for use when the number of notches required to be used exceeds three. The spring may be biased to a neutral position by a torsion spring. In a modification, two closure members and plungers may be provided, the latter being operated by two cams spaced on either side of the disc 32.
