Abstract
521,421. Valves. MILLIKEN VALVE CORPORATION. Nov. 18, 1938, No. 33634. Convention date, Dec. 6, 1937. [Class 135] In a lubricated rotary conical or cylindrical valve of the kind in which the plug is formed in two parts, the lower part 16 being adapted to move transversely under line pressure relatively to the upper part so as to seal the outlet port, a circumferential lubricant duct 26 is formed above the port only in the upper part 18 of the plug. The plug parts have a tongue and groove connection 19. The shoulder 24 on the upper plug part engages the packing 40 or a shoulder 22 in the casing. Specification 464,895, [Group XXXIV], is referred to.
