    A quite new flow control valve is disclosed, which is so contrived that valve seats opened and closed by poppets are provided on fluid passages routing from "IN"-port to "OUT"-port of the valve body and, a control mechanism to carry out a changeover of pilot pressure and a setting of time lag in response to a pulse signal of variable frequency sent from a pulse oscillator is provided for a pilot control section and, said valve seats are opened and closed through the control of said frequency as well as the setting of said time lag, thus a flux of the fluid can be controlled exactly.

    and a twin arm arm 16. When the output polarity of the pulse generator 20 changes, two-seat three-channel control valves 25 and 26 switch over. In one of the positions, the control medium from the trunk 27 is fed through channel 42 located opposite the sealing edge of the locking member 6 side, the pressure chamber 34 switched the two-seat through-valve installed at the inlet of the two-parallel passageways 4 and 5. At the same time, the working oil through the passageway 5 is supplied to the outlet channel 3, at the same time, it is controlled; and the medium from line 27 through channel 43 through throttle 44 is supplied to pressure chamber 37. Throttle 44 delays the response of the two-seat through-valve installed at the outlet of through-channels 4 and 5. After closing the valve 9, the oil flow is stopped. When changing the polarity of the generator 20, a similar consumption of working oil occurs through the passage channel 4. 1 or
    The invention relates to reinforcement.
    The purpose of the invention is to increase the accuracy and simplify the control process by providing a flow rate proportional to the number of input pulses.
    The figure shows a schematic of a valve for controlling flow.
    In the valve body 1, the inlet 2, outlet 3, and parallel pass-through 4 and 5 channels are completed. At the inlet of the passages 4 and 5 there is a two-seat valve with a stop valve 6 and 7, and at the exit there is a two-seat valve with a stop valve 8 and 9. In the passage valve the bodies face sealing edges to each other and
    connected in pairs by rods 10 and 11. (.
    Valve contains a flooring
    Electromagnetic actuator with permanent magnets 12-15. The anchor of the drive is made in the form of a two-arm lever 16 fixed on the pin 17 and made of a material with low residual magnetization, for example, of soft iron. The coils 18 and 19 are wound on measles, each of the ends of which is connected to each other, and one common connection is grounded, and the other is connected to the output of the pulse generator 20. The axes of the through valves are perpendicular to the axis of the electromagnetic drive.

    The lever 16 communicates through the rods 21 and 22 to the shut-off members 23 and 24 of the twin-seat track-channel valves 25 and 26 of the control, connected to the head HbLMH 27 and 28, control 29 and 30 and drain 31 and 32 main lines, respectively. Pressure lines 27 and 28 are connected to power supply 33. The locking bodies of the through valves have pressure 34-37 opposite to the sealing edges of the chamber, in which the springs 38-41 are located. Pressure chambers 34 and 36 are communicated by channels 42 and 43 to control line 29, in K; anal 43, a throttle 44 is installed. Pressure chambers 35 and 37 are connected by channels 4s and 46 to control line 30, and throttle 47 is installed in channel 46.
    In the initial position, for example, when the polarity of the output of the pulse generator 20 is negative, the left end of the lever 16 represented the south magnetic pole (S), and the right end the north (N), and therefore the lever turns counterclockwise., The drawing shows the position when the flow of working oil from the inlet channel 2. to the outlet channel 3 is completely stopped: the passage channel 5 is blocked by the locking member 9 at the inlet, and the duct 4 is blocked by the locking member 8 at the outlet, because the control

     The medium from the power source 33 is supplied to chambers 35 and 36. When the output polarity of the pulse generator 20 is changed, valves 25 and .26 are switched, at which in valve 25 under the action of pressure differential, the locking member 23 blocks the drain line 31 and informs the pressure main 27, with the control line 29a in the valve 26, the rod 22, the locking member 24 moves downward, shutting off the pressure line 28, while the control line 30 connected to the pressure chambers 35 and 36 communicates with the drain line 32.
    Control medium from line 27 via channel 42 is supplied to pressure chamber 34, opening the valve 7 and closing valve 6, the working oil through channel 5 is fed into output channel 3. At the same time, control medium from highway 27 through channel 43 through throttle 44 is fed to pressure chamber 37. The throttle 44 delays the actuation of the locking bodies 8 and 9. After the locking body 9 is closed, the flow of working oil stops again. With the new change of the polarity of the generator 20, a similar consumption of working oil occurs through the passage channel 4. Claims of the invention
