Abstract

20,740. Weir, W. Oct. 13. Check valves.-A valve for gas or liquid pumps consists of an inverted cup-shaped piece A, Fig. 3, of stamped or spun metal, pressed to its seat at B by a spring and guided by a metal cylinder or framework F pressed or cut from a plate G bolted to a base-plate L. The lift of the valve is limited by the part B coming in contact with the part F or by the crown E touching a plate J. In a modification, Fig. 2, the valve A has a sunk crown E<1> so that in air-pumps the clearance volume is reduced. The guard-plate G, Fig. 3, accommodates several valves and may be corrugated or provided with an upturned lip for strength.
