Valve for control of fluids with supply of pressurized fluid

The valve (1) is for control of fluids under high pressure, for fuel injection at an internal combustion motor. The piston (15) of the pressure conversion system, to compress the fuel from a delivery pressure at the inflow feed (2) into a high pressure for injection, is at least partially within the jet needle (23) with a longitudinal movement. A part of the high pressure zone (4) is additionally within the jet needle, defined by the jet needle and its inner piston.
