Abstract

The outlet valve (1) is arranged in the connection (4) between an i.c. engine fuel injection pump chamber and an injector (3). It comprises a valve body (9) with a passage (19) to a seat (14) for a closure member (16;17), opening against a spring (20) contained in a bore (8) in the valve housing (5). The closure member contains a passage (23,26,30), closable by the spring-loaded ball (32) of a non-return valve (33), which opens to relieve pressure surges when the injector needle seats at the end of the pump delivery stroke. The seat (31) of the non-return valve is formed by a plug (29) with a bore (30) which is pressed into the bore (26) of the member (16) contg. the spring (35).
