Abstract

1487686 Valves GEWERKSCHAFT EISENHUTTE WESTFALIA 27 Jan 1975 [30 Jan 1974] 3480/75 Heading F2V A main valve 18 controlling communication between an inlet 27 and an outlet 28 opens when inlet pressure is admitted to a cylinder 23 by a pilot valve 34 and closes slowly after the pilot valve has closed, the rate of closing being determined by the rate of flow from the cylinder through a discharge nozzle 26. The nozzle may be replaced by others differing in size and the travel of a piston coupled to the closure member may be adjusted by altering the position of a cylinder cover containing the nozzle. The outlet 28 may supply spray nozzles for mining machinery while the pilot valve is operated by a cam moved by an arm extending into the path of the machine. A detailed construction is illustrated in Fig. 1 (not shown).
