Abstract: A pressure-regulating valve for a fluid medium that is at system pressure, e.g., for system pressures >1000 bar, has a valve housing with an inlet channel and at least one outlet channel. A valve seat arranged in the valve housing has a conical recess holding an axially mobile valve body with a lateral outer surface at least part of which is conical. The interaction of the valve body and valve seat regulate throughflow of medium from the inlet channel to the outlet channel. The valve seat, adjacent to the lateral outer surface of the valve body, includes a first pressure chamber from which there extends, in the direction of movement of the valve body, a throttle gap along the lateral outer surface of the valve body. The conical lateral outer surface of the valve body extends, in the direction of movement of the valve body, on either side of the pressure chamber through the conical recess of the valve seat.
