PUMP FOR DIESEL OIL FEED INTO ICE Russian patent published in 2015 - IPC F04B53/10 F02M59/46 F16K15/00 

Abstract RU 2555097 C2

FIELD: engines and pumps.

SUBSTANCE: invention relates to ICE high-pressure fuel pumps. Invention discloses pump for diesel oil feed provided with check valve (9). Said valve is arranged in channel (3) for fuel feed into ICE and equipped with shutoff valve (10). The latter displaces between position whereat it opens pressure channel (3) and position whereat it shuts off the latter. This pump assy comprises stroke limiter (11) arranged in pressure channel (3) to make shutoff valve seat and to retain shutoff valve (10) after opening of check valve (9), and seal (23) arranged between the wall of pressure channel (3) and limiter (11).

EFFECT: higher reliability of pressure channel isolation, ruled out radial and/or axial displacements of shutoff element in seats, decreased wear.
