FIELD: machine building. ^ SUBSTANCE: shut-off electro-magnetic valve consists of direct-flow case with inlet and outlet orifices, of spring-loaded cap and of crosspiece. The crosspiece is fixed in the case and is equipped with an orifice for the rod of the cap. An internal cylinder boring is made in the case. The boring is conjugated with the inlet and outlet orifices along conic surfaces. The cap corresponds to a cylinder with similar conic tapers on ends. The coil of the electro-magnet is secured on external surface of the case. The cap is composed of two parts. A magnet-solid insertion is positioned between parts of the cap. A rod is attached to the part of the cap on the side of the inlet orifice. Together with a spring the rod passes through the orifice in the second part of the cap. ^ EFFECT: extended functionality of shut-off valve and reduced dimensions. ^ 1 dwg |
