The present invention relates to the field of hydraulics and can be used as hydraulic equipment of mobile machines.

Closest to the claimed technical solution (prototype) is a two-position valve with one solenoid, comprising a housing, the bores of which has a sleeve with valve, an electromagnet with a backup control button and return spring.

The spool is moved in one of the extreme positions under the action of an electromagnet and returns to the other extreme position under the action of a return spring by removing the voltage from the coil of the electromagnet (Waakirchen. "Hydraulic equipment mobile machinery Handbook" ed. Mashinostroenie, Moscow 1983 Str, RES).

Well-known advantages of the specified valve is a simple design and low cost to manufacture.

The disadvantage of this design is that the coil of an electromagnet considerable time (the whole process of operation of the hydraulic system is energized. This leads to the necessity to perform the design of the coil is more cumbersome, in addition decreases the reliability of the valve and increases power consumption.

The technical object of the present invention is to remedy these disadvantages put the m changes structurally-schematic diagrams of the valve using pulsed electric control signals.

The problem is solved in that in the claimed off the valve, comprising a housing with an integrated electromagnet, a system of canals, a cylindrical bore in which is mounted a sleeve and a spring-loaded valve in the valve, protruding beyond the sleeve, perpendicular to its axis, a fixed rod, the other end of which moves in figure the slot of the copier according to the invention the rod, and hence the spool, due curly groove copier, have the opportunity to lock in two positions after applying a pulse of electrical control signals to the electromagnet.

Figure 1 shows a valve, the valve is in the right position (in the drawing).

Figure 2 shows the valve, the valve is in the left position (on the drawing).

The valve includes a housing 1 with an integrated electromagnet 2, with drain channels 3, cavity 4, the feeder 5, a sleeve 6, which moves the spool 7, the spring-loaded by a spring 8, in the part of the valve protruding beyond the sleeve, fixed to the rod 9, the other end of which moves in figure groove 10 of the copier 11.

The valve works in the following way:

When applying a pulse signal to control the armature of the electromagnet 2 is moved to the right (p the drawing) and, overcoming the force of spring 8 moves the spool 7 in the sleeve 6. Together with the spool, making a translational oscillating motion, will move the rod 9, the tracking pattern shaped groove 10 of the master Cam 11 from position I to position II. After passage of the pulse control signal through the electromagnet 2, the valve 7 under the action of the spring 8 moves to the left (in the drawing), the rod 9 in the groove 10 is moved from position II to position III, where and locks. When the drain channel 3 is closed, and open channel is connected with the supply channel 5. This condition of the valve shown in figure 1

When applying the next pulse of the control signal repeat all the steps listed at the beginning of the description of operation of the valve, and the rod 9, the tracking pattern shaped groove 10 of the master Cam 11 moves from position III to position IV. After passage of the pulse control signal through the electromagnet 2, the valve 7 under the action of the spring 8 will move to the left, and the rod 9, the tracking pattern shaped groove 10 of the copier 11, will move from position IV to position I, where and locks. While the supply channel 5 will be cut off, abdominal channel 4 will be connected with the drain channel 3. This condition of the valve shown in figure 2.

Thus the valve for implementation through the management functions of the Executive mechanism when applying a pulse of electrical control signals on one magnet.

A two-position valve with impulse control, comprising a housing with an integrated electromagnet, a system of canals, a cylindrical bore in which is mounted a sleeve and a spring-loaded valve in the valve, protruding beyond the sleeve, perpendicular to its axis fixed rod, the other end of which moves in figure groove copier, characterized in that the rod, and hence the spool, due curly groove copier, have the opportunity to lock in two positions after the filing of a pulsed electrical signals to the electromagnet.
