Abstract

621,808. Valves. ALLEN, G. R. Aug. 27, 1946, Nos. 25586/46 and 9576/47. [Class 135] A spring-loaded relief valve having a closure 2 is formed with a flange 5 which forms, with a curved surface 6, a flow orifice, the pressure drop across which is stated to maintain the pressure at the inlet to the valve substantially constant during flow.
