The aim of the invention is to improve the speed of the distributor. The goal is achieved in a reverse push-pull valve consisting of AND serially connected cells, each of which contains a relay, the first winding terminal of the first relay being connected to Kei years of the first and second dissolving diodes and through its own the self-blocking closing contact to the first output of the diode bridge, the anode of the first release of the first cell diode is connected to the control input of the distributor, the anode of the second expansion The connecting diode of each cell is connected to the communication bus with the anode of the first-pass diode of the next cell, the first and second inputs of the diode bridge are connected to the first and second power lines cooTBefd BeHHo,; each of which, respectively, via the first and second closing contacts of the second relay is connected to the corresponding cell communication buses, the second output winding of the first relay through the disconnecting contact of the second relay is connected to the second output of the diode bridge, a third two-winding relay is inserted into each cell of the BHOJ-O reverse switch the magnetic memory, the power supply wires are connected to the opposite sources of a pulsed power source, the first terminals of the switching and disconnecting windings of the third two-winding relay with magnetic memory combined with the first output winding of the first relay; the second output of the switching winding of the third double-winding relay with magnetic memory combined with the output of the winding of the first relay; the second output of the disconnecting winding of the third two-winding relay with magnetic memory through the third closing contact of the second relay bridge, the first output winding of the second relay through the disconnecting contact of the first relay is connected to the primary output of the diode bridge, the second output winding of the second relay through parallel connected Werth make contact and the second normally open contact of the third relay roedinen to the second output of the diode bridge. The drawing shows the electrical circuit of the proposed reverse push-pull valve. The distributor contains in each cell the first relay 1 with the closing contact 1 and the opening contact l, the second relay 2 with the opening contact 2 and the first, second, third, fourth closing contact whether 22,2,24,25, two-winding relay 3 with magnetic memory and the closing contact 3c, the diode bridge 4, the decoupling diodes 5 and $, the power bus 7 and 8. Control input 9 is connected to the first cell, and there are busses 10-12 between the adjacent cells. Reversible push-pull valve works as follows. Tires 7 and 8 are provided with clock pulses for switching cells. In operation, the push-pull reversal will distribute a "head" in the forward direction to the tire 7, plus a power source, to the tire. 8 —Dinus, and when operating in (The opposite direction to bus 7 is supplied to minus power source, to bus 8 — plus. In the initial state, all relays are disconnected, to bus 7 is fed to the power supply, to bus 8 — minus the power supply of all relays is interrupted and the circuit does not consume energy. To switch on the first cell, it is necessary to shortly supply plus the power source to input 9. At this, the high-speed relay 1 turns on and becomes energized for the switching winding of relay 3. Relay 1 included in the circuit: plus power supply , input 9, diode 5, relay coil 1, contact 2 relay 2, bridge 4 diode, bus 8, minus power supply source. Relay 1 is self-locking via a circuit: plus power supply, bus 7, bridge diode 4, make contact 1 relay 1, relay 1 winding, contact 2 relay 2, bridge diode 4, - power bus 8, minus power source. Receiving winding 3 winding will receive power through the same circuits. Last when turned on by its contact 3 | prepares a relay 2 turn-on circuit After that, the power supply is disconnected, the relay is disconnected .1, -re le 3 will be held in the on position sus- pagd Tew. When the next clock feed is applied, a voltage pulse across the tires 7. and 8 is disabled and the high-speed relay 2 of the first cell will become self-blocking. Relay 2 is switched on via a circuit: power supply voltage, bus 7, bridge 4 diode, i / break contact, relay 1, make 3 contact of relay 3, bridge 4 diode, bus 8; minus power source. Self-locking of the relay 2 is carried out by its contact 2j. Relay 2, having turned on, with its contacts will close the switching-on circuit of relays 1 and 3 of the second cell and turning off the relay 3 of the first distributor cell. Relay 1 of the second cell, including, also becomes self-blocking. The relay of the second cell is switched on via the circuit: plus power supply, bus 7, contact 2 of relay 2 of the first cell, bus 10, diode 5 of the second cell, winding relay 1, contact 2j of relay 2, bridge diode 4, bus 8, minus power supply .

During the next pause between pulses, the relay 2 of the first cell and the relay 1 of the second cell are disconnected, and with the arrival of the next clock pulse, the relay 2 of the second cell and relay 1 of the third cell are turned on and the relay 3 of the second cell is turned off, etc. The last clock pulse will turn on relay 2 and turn off relay 3 of the last distributor cell. After that, the distributor comes to its original state. The operation of the distributor is provided under the condition that the pulse duration of the supply voltage is longer than the turn-on time of relays 1 and 3 of the next switch-on time slot of the previous one. j cells, and the duration of the pause between pulses is longer than the switching time of the relay 1 and 2 of the corresponding cells of the distributor. In addition, the turn-on time of relay 1 must be less than the switch-over time of relay 3. Thus, when the distributor is working during the delivery of a clock pulse. Relay cell 2 of the preceding cell, relay 1 and 3 of the next cell are switched on sequentially, and relay 3 of the previous cell turns off. and during the pause between pulses, the relay 2 of the previous cell and the relay 1 of the subsequent cell are turned off. To make the switch:. The cells of the distributor in the opposite direction need to change the durability of the voltage of the clock pulses fed to the buses 7 and 8.. Suppose the relay is turned on the 3rd third cell, and at this moment with. The purpose of the reversal work was to change the polarity of the voltage of the clock pulses in this way, the bus 7 is fed to the minus power source, and to the bus 8 — plus. In this case, with the arrival of the alternate. a clock pulse is turned on by the relay 2 of the third cell, the relay 1 and 3 of the second cell, and the 3-t relay of the cell is turned off. In this case, the third cell relay 2 is switched on as previously described, the circuit. Relay 1 and 3 of the second cell is switched on along the circuit; plus power supply, bus 8, pin 2z relay 2; third cell, bus 11, diode 6 of the second cell, relay coil 1 and switch-on relay coil 3, contact 2 / .le 2, bridge diode 4, bus 7 minus the power supply. Relay 3 of the third cell is disconnected in a circuit: plus, power supply, bus 8, contact 2, relay 2 of the third cell, diode 5, disconnecting winding of relay 3, contact 24 of relay 2, bridge 4 diode, bus 7, minus the power supply. “In the future, with the arrival of the next clock pulses, switching of the distributor cells will occur in the opposite direction, as described above. . Depending on the specific conditions, mechanisms (not shown) may be activated by relay contacts 1,2 or 3 of the distributor cells.
