Abstract

A solenoid valve has a main stage and a pilot stage, wherein the main stage includes a switching element which in the closed condition of the solenoid valve closes a main flow path from a high-pressure side to a low-pressure side and in the open condition of the solenoid valve clears the main flow path. In its closed condition, the pilot stage closes a pilot flow path from the high-pressure side to the low-pressure side and in its open condition clears the pilot flow path. The pilot flow path leads through a control chamber which is in permanent flow connection with the high-pressure side via a control opening. The pressure existing in the control chamber acts on the switching element. The pilot stage includes a coil and a pilot valve element movable by a magnetic field of the coil, which are arranged at the switching element and are moved with the same.
