Made to solenoid valves

Solenoid valve comprising an electromagnet subassembly and a pneumatic switching assembly with valve plug mechanically associated with the said electromagnet subassembly, the pneumatic switching subassembly being composed of a body enclosing the valve plug trapped between two sealing seatings facing each other, the movement of the said valve plug being controlled firstly by a spring located in the mobile core of the electromagnet subassembly through a pusher, and secondly by a means that forces the valve plug into contact on the upper seating of the pneumatic switching assembly when the electromagnet is energized, this solenoid valve being wherein said electromagnetic subassembly comprises four cylindrical pins at its assembly plane on the pneumatic switching subassembly, each cylindrical pin being provided with a transverse cavity formed on the generating line of the pin and terminating with the frustum of a sphere, and in that the pneumatic switching subassembly comprises four cylindrical cavities at its assembly plane with the electromagnet subassembly, designed to hold the pins of the electromagnet subassembly, transverse cavities being formed on the body of the pneumatic switching subassembly, these cavities terminating on the corresponding generating line of the cavities into which the pins will be fitted, and the said cavities terminating in the frustum of a sphere such that, after the two subassemblies are assembled together, the transverse cavities of the pins of the electromagnet subassembly are facing the transverse cavities of the said pneumatic switching subassembly, delimiting housings into which a ball will fit.
