DEVICE OF SUPPLY OF FUEL IN THE CYLINDER OF THE ENGINE OF INTERNAL COMBUSTION Russian patent published in 2019 - IPC F02M61/00 F02M61/16 F02M53/06 

FIELD: internal combustion engines.

SUBSTANCE: invention relates to fuel injection devices in a cylinder of an internal combustion engine. Device comprises housing (1) with an internal bore, two hydraulic cavities (6 and 12) are separated by a spring-loaded valve (9), the lower part of the housing is rigidly connected to conical sleeve (16) rigidly connected to diffuser (17), and to its cylindrical part conical valve (20) is coaxially mounted to block the openings of the diffuser (18). Lower conical sleeve (23) is made with drainage channels (24), in a part of the cavity free from spring-loaded valves light guide (30) is fixed, connected to laser emitter (31). In the upper part of the body there is a movable cylinder (3) with the possibility of moving along the axis of the body, inside the cylinder there is a hydraulic cavity with supply (7) and discharge channels (8), and in the lower part of the cavity there is a spring-loaded valve with a central blind channel (10), which through the side through holes (11) provides communication between the cavity and the lower hydraulic cavity, at the same time, the valve in the upper part is provided with an annular stop (15) with the possibility of mating with an annular abutment (5) of the movable cylinder. Upper part of the rolling cylinder is rigidly connected to rod (25), moreover, the position of the rod depends on the position of the power regulator by the free rolling of the ball or roller bearing (26) on the surface of the profiled cam slot (27), and the position of the cam mechanism determines the position of the power regulator.

EFFECT: technical result is to provide enhanced functionality by providing control and changing the amount of fuel supplied to the cylinder of the internal combustion engine.
