Abstract

103,383. Andersson, K., and Greenwood & Batley. March 18, 1916. Safety-valves.-A safety-valve loaded by a spring or weighted lever has the valve member and seat provided with radial extensions so shaped as to form a passage of gradually increasing crosssectional area such that the escaping fluid is reduced to atmospheric pressure before leaving the passage. In the form shown in Fig. 2, the valve member g is adjustably loaded by a spring j and is guided by a tail-piece h. The extension l on the valve member is provided with a turned-over lip n to increase the power of the escaping fluid to lift the valve; this lip may also be surrounded by a cylindrical casing o so as to form a narrow passage p, through which the escaping fluid acts to cause a reduction of pressure above the valve member. The extension f on the seat is formed with a groove r communicating with the outlet or the atmosphere through ports s. This feature may be dispensed with.
