HYDRAULIC CONNECTING MECHANISM Russian patent published in 2017 - IPC F02M51/06 F02M61/16 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in fuel injection systems of internal combustion engines (ICE). Disclosed is fuel nozzles hydraulic connecting mechanism having cup-shaped housing (31) with bottom (311) and side wall (312), installed in barrel-like housing (31) with possibility of directed axial movement in it piston (33), filled with liquid gap (35) between piston (33) and cup-shaped housing bottom (311), located with facing away from piston (33) of cup-shaped housing (31) external side membrane (36), which limits compensating cavity (37) hydraulically connected with gap (35), and resilient element (40) acting on membrane (36) by its axially directed force. To achieve hydraulic connecting mechanism low total stiffness with its required developed force, resilient element (40) is made in form of spring bracket (45) fixed on cup-shaped housing (31), which adjoins membrane (36) in cup-shaped housing bottom (311) area with axial pre-stress.

EFFECT: disclosed is fuel nozzles hydraulic connecting mechanism.
