Abstract
281,624. Hoppler, H. Dec. 1, 1926, [Convention date]. Compound piston pumps; regulating compression.-The piston of a compound compressor is double-acting and stepped on both sides; the gas is compressed in stages and delivered through an intermediate receiver to a final delivery chamber. Gas is drawn through a pipe 9 e.g. from the evaporator of the refrigerating machine, and compressed in the space 1, passing out through lift valves 12, 13 to a receiver, not shown, connected with the second stage inlet pipe. The second stage compression spaces receive the gas through lift valves 17, 20 and deliver it through lift valves 18, 21 e.g. to the condenser of the machine. The suction and delivery spaces of each stage are connected through a safety by-pass valve. A half-turn of these valves accompanied by interchange of the inlet and outlet valves allows the condenser contents to be returned direct to the evaporator.
