Abstract

851,065. Valves. SUPERFLUSH Ltd. Nov. 12, 1958 [Oct. 8, 1957], No. 31483/57. Class 135. In a flushing valve of the type having a side inlet 9 and axial outlet 10 and a main valve 19 carried by a leaky piston 26, and a pilot valve 17 which is unseated by an actuator 12 to relieve pressure above the piston and allow the main valve to open under the inlet pressure, and in which the main valve closes during the time taken to re-charge the space above the piston through the leak (23), the pilot valve 17 has a compression loading spring 21 which is retained by a bridge 28, this bridge being located both longitudinally and circumferentially in the piston 26 by co-operating parts thereon. The bridge, Fig. 4, has a central seating 35 with a spigot 36 for the spring and side lugs 37 to 40 which engage underneath the sides of recesses 33, 34 in ledges 31, 32 in the top of the piston (Fig. 2). A loose telescopic extension 18 of the pilot valve follows the rise of the piston and allows the pilot valve to reseat and remain reseated until the main valve has closed, whether the actuator 12 is withdrawn or not.
