Abstract

579,391. Valves. PACKLESS METAL PRODUCTS CORPORATION. Dec. 14,1943, No. 20955. Convention date, Dec. 18, 1942. [Class 135] [Also in Group XXVI] A valve comprises a ported thin resilient sleeve 31 fitted in a bore having inlet and outlet ports 13, 15. The valve is rotated by a hand wheel 36 attached to a threaded spindle screwed into the cover. The sleeve 31 is expanded by fluid pressure to prevent leakage and a spring-pressed washer 40 -engages the end to maintain contact with the bore. A collar 32 has a thin resilient sleeve 33 formed on it which is also pressed against the bore 12 by leakage fluid pressure and a spring-pressed washer 41.. In a modification, the ports 13, 15 are in line and the sleeve has two ports and access is arranged from the inlet port to the interior of the sleeve to maintain sealing pressure ; in this constructure the spindle is not threaded. Specification 564,892, [Group XXVIII], is referred to.
