The valve in order to control the terminal area which is provided inside the high pressure liquid system of the high pressure liquid system and the fuel injector for the especially internal combustion engine

摘要

The valve component (72) it has possessed the valve by this invention. The valve component (72), the longitudinal direction axis (73) sliding we are guided possibly with direction, the valve pressure chamber (77) have rushed inside, the seal surface (81) it has possessed on the end face which extends with intersection direction at the same time the valve pressure chamber (77) inside, that longitudinal direction axis (73) vis-a-vis. This seal surface (81) with having, the valve component (72), the seat which extends with intersection direction the longitudinal direction axis (73) vis-a-vis (79) with cooperating, opening which is encircled the seat (79) by (78) it has reached the point where almost it closes at least the valve pressure chamber (77) vis-a-vis. Opening (78), the terminal area which leads (64) is connected to the low pressure territory. The valve component (72), the terminal area (64) the plug body which rushes inside (83) it has possessed. The plug body (83) due to, the valve component (72) having, the seal surface (81) with the seat (79) from when being made to alienate, the valve pressure chamber (77) from the liquid which flows out is guided in order the longitudinal direction axis (73) for the resultant force which causes with direction almost not to exist at least with this liquid the valve component (72) vis-a-vis.
