    The valve includes a cup-shaped housing (10) having a port (12) in the base wall. A tubular valve element (14) is engageable with the base wall about the port under the action of a spring (21). A solenoid assembly (17), when operative, lifts the valve element from the base wall to allow flow through the port. The valve element (14) has a location element (16) slidable within the bore therein to locate the valve element in the closed position.

    This invention relates to a valve industry.
    A solenoid fluid control valve is known, comprising a non-magnetic body with a cup-shaped part in which a spring-loaded locking body of a rim shape with a flange is installed, made of a magnetized material, interacting with the saddle and controlled by an electromagnetic actuator, in the foot of which there is a notch and It has one end of the guide element.
    A disadvantage of the known device is the significant power of the electromagnet due to pressure fluctuations of the working medium, as well as due to the presence of pressure of the medium on the locking member.
    The aim of the invention is to increase the reliability and reduce the power of the electromagnet.
    This goal is achieved by the fact that in a solenoid valve controlling the current medium containing a non-magnetic housing with a cup-shaped part in which is installed a spring-loaded locking organ tubular with a flange made of a magnetized material that interacts with the saddle and is controlled by an electromagnetic actuator in which a notch is made in its foot and it houses one end of the guide element, the locking member is made with a through central hole, the diameter of which is larger than the diameter of the saddle, and The yug element is made in the form of a ball mounted for movement in the central opening of the closure member.
    On figl shows the solenoid valve, the cut, in figure 2 - the same, his version
    In the housing 1, made of a non-magnetic material and having a cup-shaped part 2, a closure body 3 of tubular shape with a flange 4, made of a magnetizing material, is installed. The locking organ is loaded with the pond 5. In the locking organ 3 there is a through central hole b, in which is placed with
    the movement of the guide element 7 is in the form of a ball, the diameter of the central hole b being larger than the diameter of the seat 8, which is blocked by the locking member, which is controlled by an electromagnetic actuator 9, due to the chego of the foot 10 of the latter, a notch 11 is inserted, into which the guide element 7 enters In the case are made passages 12 and 13.
    In the valve of FIG. 2), a longitudinal slit 14 is made in the electromagnetic actuator 9, through the second, with the valve open, the working medium enters the passage channel 13.
    The valve operates as follows.
    When the medium is supplied under pressure to the channel 12, when the electromagnetic actuator 9 is de-energized, the locking member 3 is pressed to the seat by means of a spring 5. When current is supplied to the electromagnetic actuator, the locking member 3 moves away from the saddle 8, and the guide element 7 under the action of the working medium moves in the direction of the stop 10 to contact with the wall of the recess 11 and the working medium enters from the channel 12 into the channel 13. The locking member 3 in the open position is pressure balanced, in the closed position the locking member having a small area its pressure is also balanced, so the spring 5 may be selected relatively weak, which leads to a decrease in power of the electromagnetic actuator. When the valve is open, the guide element 7 is also pressure balanced.
    When the medium is fed in the opposite direction to the channel 13, the guide element 7 is pressed by the medium to the seat 8, and in order to prevent the guide element from functioning as a locking member around the circumference of the saddle, a plurality of grooves are made. In the open position, the guide element is again balanced by pressure.
    This valve design reduces valve drive power.
