Abstract

490,789. Valves. ROUSSEL, E. J. F. June 16, 1937, No. 16720. Convention date, June 16, 1936. [Class 135] A rotary plug cock is provided with an externally threaded sleeve 3 surrounding the actuating spindle 6 of the plug 1 for lifting the plug from, and applying it onto, its seat before and after rotation to a new position. A washer 15 prevented from rotation by a projection 17, as shown on the left-hand side of the Figure, or a diaphragm 20 secured in position by the cover 8, as shown on the righthand side of the Figure, is provided between the top of the plug and the bottom of the sleeve 3 to maintain fluid tightness, a spring 19 serving to keep these parts in contact.
