Abstract

664,420. Pressure relief valves. SHAW, W. W. April 5, 1950 [Jan. 14, 1949], No. 1108/49. Class 135. A relief valve for a pressure cooker comprises a closure member 20 urged to seat in a bore 18 by a spring 23 attached to a plunger 25 engaging an inclined cam groove 17 in a member 10 which is rotatable to vary the loading on the closure member. The member 10 is retained in a recess in the cooker lid 14 by a spring clip 15 to form a duct 26 connected to a groove 27, and relief takes place past the member 20, through the duct and the groove to the atmosphere.
