Abstract

492,463. Reciprocating pumps. HYLAND, C. May 22, 1937, No. 14257. [Class 102 (i)] Cylinders 3, 4, arranged in the walls of a casing 1, contain plungers 5, 6, which are held in contact with an operating cam or eccentric 2 by liquid pressure. For this, purpose the liquid is supplied to the pump by a precompression pump, or the liquid is subjected to air pressure supplied by a pump 8, which also is driven by the eccentric 2. A hand-operated valve 14 controls the communication of the supply pipe 15 with the suction pipes 10, 11 of the cylinders 3, 4. By means of the valve 14 either or both cylinders may be put into or out of action. The pump may, e.g. supply operating liquid to a motor, in which case the pump 8 exerts air pressure on the exhaust liquid from the motor.
