Abstract:
1. A pressure reducer, comprising: a valve having a valve body, a valve seat and a movable valve piston that interacts with the valve seat in an operating state of the pressure reducer; a spring provided in the valve body and configured to exert an actuating force on the valve piston such that the valve piston is moved away from the valve seat; a solenoid coil configured to exert a magnetic force which is superimposed on at least one of a closing force and the actuating force which acts on the valve piston; a high pressure inlet; and a low pressure outlet, wherein when the valve piston is displaced away from the valve seat, a fluid path is opened between the high pressure inlet and the low pressure outlet, and on the valve piston, during the operating state, the closing force caused by pressure at the low pressure outlet acts towards the valve seat, wherein the valve piston is configured so that the high pressure inlet only faces one radial surface of the valve piston with the valve in the closed state.
