Abstract
519,031. Fuel injection pumps. SKODA WORKS, PLZEN. Sept. 12, 1938, No. 26549. Convention date, Sept. 11, 1937. [Class 102 (i)] The pressure in the delivery pipes of the injection pumps of internal combustion engines is relieved by a device arranged in parallel with the non-return valve 4, 5, this device being connected by ducts 12, 13 with the working chamber 10 of the pump and with the delivery pipe 11, and containing a spring-controlled compensating member 7 the speed of movement of which is determined by the cross-sectional area of one or both of the ducts in relation to the spring 6 of the non-return valve. By this means, the pressure relief may be made the same at high and low pressures. In a modification, the pressure relieving device is mounted in the movable part of the non-return valve.
