VALVE FOR BATCHING FUEL TO INTERNAL COMBUSTION ENGINE Russian patent published in 2007 - IPC F02M51/00 F02M51/06 

FIELD: engine engineering.

SUBSTANCE: valve comprises housing and guide that abuts against the housing and provided with a conical seat. There is a space under the guide seat that is connected to the space above the valve that receives the fuel from the pressure source. The pocket connected with the passage for fuel discharge is arranged above the seat. The guide receives the spring-loaded valve gate provided with the sealing trancated cone over its periphery, and the precision compensator coaxially mounted with respect to the axis of the valve gate separates the space into the space above the valve gate and draining space that receives the power drive of the valve gate. The bottom stop of the precision compensator of pressure and the stop provided on the valve gate define a joint movable in radial and axial direction. The drive of the valve gate represents the power multi-layer piezoceramic drive whose bottom face is secured in the housing of the valve and has central opening though which the top section of the pressure compensator provided with top stop passes. The top stop of the pressure compensator is, in turn, spring-loaded by means of the compression spring to the top face of the power multi-layer piezoceramic drive.

EFFECT: enhanced precision of batching.
