Abstract: A magnetic valve (1) in which a valve housing (2), an armature tube (3), an inlet connection (4) and an outlet connection (5) form a single valve part is provided. An armature (9) made from a soft magnetic material is arranged movably inside the armature tube (3). A coil (16) is arranged externally to the armature tube (3) in such a manner that the armature tube (3) and the armature (9) are arranged inside the windings of the coil (16). A valve closing element (10) is connected to the armature (9) and is movable between a position in which it abuts a valve seat (8) and positions in which it does not abut the valve seat 8, thereby closing and opening the valve (1). In one embodiment, the flow path through the valve (1) from the inlet opening (6) to the outlet opening (7) does not pass through the windings of the coil (16). In another embodiment, the armature tube (3) comprises a closed end part (3a).

Abstract: The invention relates to a solenoid valve with a housing as well as an inlet and an outlet, wherein the solenoid valve further comprises a valve element and an orifice, wherein the orifice comprises an orifice inlet and an orifice outlet. In order to increase the maximum operating pressure differential of the solenoid valve the orifice is provided in a membrane and the orifice has a diffuser characteristic in a direction from the orifice inlet to the orifice outlet.
