Abstract

663,945. Flushing valves. TIPPING, W. F. July 5, 1949 [July 1, 1948 ; Oct. 14, 1948], Nos. 17721/48 and 26721/48. Class 135. A flushing valve for supplying a flow of predetermined duration comprises a casing 11 with an inlet 12 and an outlet 13, a closure member 14 attached to a spring bellows 18 and seating on a ridge 16, and an operating plunger 21 which, when depressed, collapses the bellows and unseats the member 14. The bellows communicates with the casing through holes 33 controlled by a valve 34 which opens during collapse of the bellows, and through a variable restriction 39 which times the expansion of the bellows and hence the duration of flow. The plunger acts on the bellows through a lever 24 which abuts a piston 42 in a cylinder 40 attached to the bellows. The cylinder communicates with the interior of the bellows through a restriction 41 and thus, if the plunger is held down, the cylinder can move down over the piston to seat the member 14. In a modification, the bellows communicates with the atmosphere via a check valve and a variable restriction, and the piston and cylinder are replaced by a mechanical trip mechanism.
