Abstract
614,463. Check valves. KENDRICK, J. F. July 12, 1946, No. 20927. [Class 135] [Also in Group XXI] A non-return valve 3 is moulded from an elastic material in the form of a hemispherical hollow dome with a threaded cylindrical skirt. The dome is separated into segments E which part when subjected to internal pressure and close, because of the elastic deformation, when the pressure is released.
