特に内燃機関に用いられる燃料噴射装置の高圧液体システム内の接続部を制御するための弁
Document Type and Number:
Japanese Patent JP4335544
Kind Code:
B2
Abstract:
Valve for controlling a fuel injection unit for an I.C. engine comprises a valve part (72) which slides in the longitudinal direction (73) and protrudes into a valve pressure chamber (77) having a temporary high pressure. The valve part has a sealing surface (81) on a front side running across its longitudinal axis. The sealing surface is surrounded by an annular surface (84) on the front side of the valve part, the annular surface being arranged at a distance from a valve seat (79). The valve part has several openings (86) distributed over its periphery. An Independent claim is also included for a fuel injection unit for an I.C. engine. Preferred Features: The openings run radially to the longitudinal axis of the valve part and are formed by grooves arranged in the sealing surface and open to the valve seat. The annular surface has an approximate conical shape.
