The invention relates to a solenoid valve comprising a circumferential outer housing (322) and a circumferential inner housing (324) bound each other such that a first valve opening and a second valve opening are implemented. The outer housing comprises at least one outer pass-through opening (340) connected to the first valve opening by means of a first fluid channel. The inner housing comprises at least one inner pass-through opening (342) connected to the second valve opening by means of a second fluid channel. The solenoid valve further comprises a first and a second closure element (344) moveably disposed for allowing closing and opening of the first and second valve opening. The solenoid valve further comprises an electrical coil (320) disposed between the outer housing and the inner housing so that the outer housing, the inner housing, the first displaceable closure element, and the second displaceable closure element each form partial segments of a magnetic circuit when electrical current flows through the coil. Despite a large potential opening cross section, an opening time that is unusually short for electrical switched valves can thereby be achieved, because the displaced mass of the ring washer (344) is relatively small, while the overpressure in the ring gap accelerates the opening of the valve even before the magnetic field is dissipated from the coil (320). |
