FIELD: valving. ^ SUBSTANCE: valve comprises hollow housing with two open faces. A part of the housing is set into the coil of an electromagnet. This part of the housing receives hollow armature of the electromagnet. The armature has a projection from the side of one of the faces. The projection cooperates with the spring-loaded stops. The stops are arranged inside the housing for permitting radial movement and locking the armature in two positions. One of the positions corresponds to the case when the plate is pressed to the seat. According to the other version, the armature of the electromagnet is spring-loaded in the direction of the valve seat for permitting valve plate to be pressed to seat. The valve is provided with arresting mechanism. The arresting mechanism locks the armature in the open position. ^ EFFECT: reduced cost and power consumption. ^ 9 cl, 4 dwg |
