Abstract

The invention relates to reinforcement and is intended to control the flow of working medium in systems. The aim of the invention is to improve the reliability of the valve in operation by eliminating the shock interactions of the closure member with the housing elements. The cavity of the housing 1 is divided by a partition 2 into two chambers 3 and 4. In the opening of the partition 2 a double closure member 13 is passed, made in the form of a shell of elastic material filled with magnetic fluid. When one of the electromagnets 9 or 10 is turned on, channels 5 and 7 or 6 and 8, respectively, overlap. When electromagnets are de-energized, the case of simultaneous communication of channels 5 and 7, 6 and 8 is possible. Zil. 12 Yu co IND ate to co 00 Fig, 1

The invention relates to valve construction and is intended to control the flow of a working medium in systems.

The aim of the invention is to improve the reliability of the valve by eliminating the shock interactions of the closure member with the housing elements.

FIG. 1 shows the proposed solenoid valve with the extreme position Q of the closure member in FIG. 2, the same, in the other extreme position; fig.Z - the same, with an intermediate position of the locking organ.

The dual-action solenoid valve comprises a housing 1, the cavity of which is divided by a partition 2 into two chambers 3 and 4 having inlet 5 and 6 and outlet 7 and 8 channels. In the partition 2 is made a through hole.

On the side of the input channels 5 and 6, electromagnets 9 and 10 are mounted on the outer surface of the housing 1, on which saddles 11 and 12 are made,

In the internal cavity of the valve, a double locking member 13 is placed, the parts of which are placed in the corresponding chamber and are connected to each other through an opening. The locking member 13 is a shell in the form of a shell of elastic material, sealed by its middle part in the axial hole. The shell of the locking member 13 is filled with magnetic fluid.

The solenoid valve operates as follows.

A working medium is supplied to the input channels 5 and 6 from the pressure source.

To ensure that the working medium is supplied to the output channel 8, the electromagnet 9 is turned on (with electromagnet 10 turned off). When this magnetic fluid under the action of a magnetic field flows into the left side of the constipation, g

to the saddle 11 and the current of the working environment 5 to the output channel

When the tee flows into the left side 13 of the right, it is part and the pads are depressed from the saddle 12, and it passes from the output channel 8 biodinally.

To supply the working channel 7, switch on 10 (when the valve is turned off, similar to

In order to supply the output to the electromagnet, the magnetic fluid is divided into fervent parts of it, they are pressed freely from the corresponding working media.

Claims (1)

Formula of Electromagnetic the action, which contains two chambers, has a porous body and output channels, and a through chamber of the locking body with a friend is made through the gate outside each of them there is an actuating valve with the purpose of enhancing the locking organ of the axial opening elastically elongated with its midpoint and element 13,. pressing its wall with nitric fluid. five 0 g five 0 five 0 to the saddle 11 and thus the overflow of the working medium flow from the input channel 5 to the output channel 7. When the magnetic fluid flows into the left part of the right locking element 13, its part freely sags and is pressed by the working medium flow from the saddle 12, and the working medium freely passes from the inlet channel to the outlet channel 8. To supply the working medium to the output channel 7, the electromagnet 10 is turned on (with electromagnet 9 turned off), and processes similar to those described in the valve occur. To supply the working medium to the output channels 7 and 8 simultaneously, both electromagnets are switched off. In this case, the magnetic fluid is freely distributed in the retaining element 13, both its parts freely sag and are pressed out from the respective saddles by the flow of the working medium.
