摘要： The proposal is for a magnetic valve in which a valve component (1) has a plane frontal sealing surface (3) acting with a valve seat (12) formed on a crowned seat component (6) and surrounding the outlet of a pressure channel (5) on the seat component (6). Owing to the crowned shape, the seat surface can enlarge when the magnetic valve is operated through the deformation of the region immediately adjacent to the outlet in its pressure channel (5), providing great seat precision compensating for manufacturing tolerances together with high pressure sealing of the valve.

摘要： A process for reducing the fuel pressure in a fuel injection system after the internal combustion engine supplied has been stopped, in which the high fuel pressure built up by a high-pressure feed pump (1) in a high-pressure storage chamber (common rail) (7) is discharge into the fuel tank (5) via the control valves (31) needed to control the injection process at the injection valves (11) connected to the high-pressure storage chamber (7). To this end the control valves (31) are operated in such a way that they connect pressure chamber (29) in the injection valve (11) briefly with the high-pressure storage chamber (7) or the fuel tank (5) in such a way that the pressure applied to the valve member (15) of the injection valve (11) in the opening direction remains below an opening pressure of the injection value (11), and said control valve (31, 323) operating process is repeated until a desired pressure is attained in the high-pressure storage chamber (7).

摘要： The proposal is for a fuel injection device with a reciprocating pump piston (8), the working chamber (13) of which is connected to an injection valve fitted directly on the pump housing. To control the quantity of fuel injected and the injection time there is a magnetic valve (31) arranged in a fuel channel (22) connected to the pump working chamber and used to fill and/or empty said chamber. To reduce the chambers to which high pressure is applied, the fuel channel (22) is arranged in such a way that it cuts the cylindrical drilling containing the pump working chamber and the magnetic valve is arranged at the entrance to this channel.
