Abstract
The solenoid valve of the invention comprises a housing having a fluid flow opening passage therethrough. A movable assembly is subjected to the opposing actions of a return spring and an electromagnetic coil. The movable assembly comprises an armature whose abutment against a guide defines an end position and a needle fixed to the armature, which defines with the opening a passage of minimum non zero cross-sectional area when the assembly is in the end position.
