Abstract

174,571. Sandoz, C. Jan. 27, 1921, [Convention date]. Cam - actuated pumps; revolving - cylinder pumps; regulating delivery by opening suction and delivery valves.-A rotary pump comprises a piston 7 sliding in a diametral bore 6 formed in a cylindrical body 2 which is rotated by a shaft 3 and has passages 10, 10<1> communicating with the two portions of the bore 6, the said passages alternately registering during rotation with concentric passages 11, 11<1> formed in the pump casing and communicating respectively with inlet 12 and outlet 12<1>. The piston, which comprises two heads 7, 7 connected by a rod 8 in a guiding- block 9, is actuated by .engagement with a substantially eccentric track formed on the internal surface of the ring 5, the angular displacement of which effects variations in the output of the pump. This angular displacement is effected preferably by rotation of a pinion 14 engaging teeth 13 on . the external surface of the ring, and adapted to be locked in position by the screw 15. Two or more pistons at different angles may be used in the cylindrical body. The Specification, as open to inspection under Sect. 91 (3) (a), describes also the use of single pistons. This subject-matter does not appear in the Specification as accepted.
