The invention relates to starting devices motors and can be used in installations with power sources with limited energy.

It is known device electric start engine copyright certificate of the USSR No. 1193287, CL F02N 11/08, 1984, containing the battery, capacitive drive, traction relay make contact, starter, two switches and two semiconductor diode.

All its constituent elements, in addition to semiconductor diodes are used in the composition of the claimed device.

The operation of this device is based on the fact that the capacitive drive is pre-charged from the battery, and the starter is already connected to a capacitive storage device and maintains the voltage at the starter constant.

The obstacles to obtaining this similar technical result achieved in the inventive device is the low reliability of start-up and low energy efficiency capacitive storage device.

It is also known device electric start engine copyright certificate of the USSR No. 1455030, CL F02N 11/08, 1987, containing the battery, three capacitive drive, traction relay make contact, two switches, starter, two additional relay with normally closed contacts and above the th semiconductor diodes.

All its constituent elements, in addition to relays and semiconductor diodes are used in the composition of the claimed device.

The principle of operation of this analogue is the same as the analogue of the copyright certificate №1193287, but here at the expense of increasing the number of capacitive storages provided by their alternate connection to the starter and reduces the time bit of a drive and, consequently, the change in the voltage on the starter during this discharge is reduced, and thereby increases the efficiency of the capacitive energy storage devices.

The reason that prevent obtaining this similar technical result achieved in the inventive device is that it is designed for the feeding of more than (number of drives) short-term (duration in seconds) of the voltage pulses to scroll the starter on the engine crankshaft. Re scrolling requires disconnecting the starter for the time necessary for charge storage.

The closest to the technical nature of the claimed (prototype) is a device for electric starting of the engine under the author's certificate of the USSR No. 1746045, CL F02N 11/08, 1989, containing the battery, starter, traction relay contact closure, three capacitive drive, trigger switch, three porogo the output element, decoder and six switches with the control electrodes, in which the winding of the traction relay is connected through a starting switch to the positive pole of the battery, and directly to the negative poles of the battery, starter and capacitive drive, first, second and third switches connected between the positive pole of the battery and positive poles respectively of the first, second and third capacitive storages, the positive pole of the starter motor through the normally open contact of the traction relay is connected to the outputs of the fourth, fifth, and sixth switches, signal inputs are connected to the positive poles respectively of the first, second and third capacitive drives the control inputs of the first, second, the third, fourth, fifth and sixth switches connected respectively to the first, second, third, fourth, fifth and sixth outputs of the decoder, the first, second and third inputs of which respectively through the first, second and third threshold elements connected to the positive poles respectively of the first, second and third capacitive drives, while the fourth input of the decoder via an additional normally open contact of the traction relay is connected to the positive pole of the battery.

All the elements of a prototype of the a, in addition to closing the contact of the traction relay, and includes part of the claimed device.

Your prototype by introducing a threshold elements, decoder and managed switches during the discharge of one of the capacitive drives the other two charged from the battery, so the voltage at the starter can be fed long enough.

The reason preventing people from getting in the prototype, as in the above analogues, the technical result achieved in the inventive device, is relatively low starting current. The fact that this current is determined by the energy of one capacitive drive, as both starter discharges only one drive. The increase in same capacity drives requires a very significant investment.

Technical task, which directed the creation of the invention is to increase the starting current without increasing the capacity.

The combination of the newly introduced switching elements and relations and implementation of the decoder is not an independent unit and not obvious from the prior art.

When the voltage at their inputs exceeding the threshold, they form at their outputs signals of logical "0", and when the voltage level is less than the threshold release, signals of logical "1". Thresholds triggering and releasing selected so that they are within acceptable limits of voltage changes on the drives 6÷8. When the discharge current (charge) drives 6, 7, 8 is equal to the current value of the hold switches 14, 15, 16 (17, 18, 19) at the discharge (charge) drives 6, 7, 8. The parameters of circuit elements of the device are chosen so that the current ICcharge and time tCcharge were associated with current IPdischarge and time tPdischarge ratios:

IC≈(0,5÷0,52)IP; tC(1,9÷2,0)tP.

In the initial position open button 9, the absence of voltage at the fourth input of the decoder 13, the stress on the drives 6, 7 and 8, the lower threshold elements 10, 11 and 12, and the signals of logic "1" at their outputs and the first, second and third inputs of the decoder 13, the decoder 13 generates a signal to close the switches 14, 15, 16, and 20 and opening of the switches 17, 18 and 19.

3. When the signal level of the logic "1" on the first and second inputs of the decoder 13 generates a signal for opening the switches 16 and 18. Through the switch 16 is the discharge drive 8 on the starter 2, supporting the rotation of its rotor, and through the switch 18 to the charge of the drive 7. Given the chosen parameters of the drives to the time of full discharge drive 8 drive 6 charge, i.e. the charge current passing through the switch 17, reduced to the current value of the hold switch, and the switch 17 is closed, and the drive voltage 6 reaches the value of the threshold element 10, which generates a signal with a logical level "0"is received at the first input of the decoder 13. The current flowing through the switch 16, and the drive voltage 8 when discharge decreases, reaches the current values of the hold switch 16 and a threshold release threshold element 12. The switch 16 is closed and the element 12 generates at its output a signal of logic level "1"which is supplied to the third input of the decoder 13. The charge storage 7 at this time continues.

4. When the signal level of the logic "1" on the second and third inputs of the decoder 13 generates a signal for opening the switches 14 and 19. Through the switch 14 is a discharge drive 6 on the starter 2, supporting the rotation of its rotor, and through the switch 19 to charge the drive 8.

The current passing through the switch 14, and the drive voltage 6 at its discharge decrease, reaching values respectively current hold switch 14 and the threshold release threshold element 10. The switch 14 is closed. Element 10 generates at its output and the first input of the decoder 13, the signal of logic level "1". The charge storage 8 at this time continues.

The switch 15 is closed. Element 11 generates at its output and the second input of the decoder 13, the signal of logic level "1". The charge storage 8 at this time continues.

The following describes the alternating discharge drives 8, 6, and 7 on the starter with 2 simultaneous charge of two other drives from the battery 1 is repeated.

The input voltage to the starter motor 2 is determined by the duration of the closed state of the switch 5. When opened, the last winding 3 of the traction relay is de-energised and the contact 4 is opened, interrupting the chain feed the starter 2.

In some cases, e.g. in case of high viscosity oil in the engine at low temperatures, the torque on the shaft of the starter, develop a bit of a drive, is insufficient to start the engine and there is a need in the short-term increase current starter.

In this case, by pressing button 9, in which the positive pole of the battery 1 is connected to the fourth input of the decoder 13. When receiving the fourth input of the decoder voltage output of the battery 1, the decoder 13 generates all seven of their outputs and the control inputs of the switches 14÷20 signals the opening of these switches. The switches 14÷20 is opened, which results in the discharge of all three drives to the starter 2. In addition, through the switch 20 to the starter motor 2 is connected and the battery 1. As a result, the residence time button 9 is in the closed state current starter fold increases compared with the case of the discharge on the starter 2 only one of the drives.

After releasing (opening) button 9 to start the engine continues in the above-described mode alternate discharge drives simultaneously charge two others. However, even short-term increase inrush current sufficient to increase the torque on the shaft of the starter is on required to start the engine level.

Thus, the technical result achieved in the proposed device is a significant increase in the starting current of the starter in comparison with analogues and prototype.

The device is easily realizable. It can be performed on the same elements as the prototype. As a threshold element can be used Schmitt trigger. The switches can be implemented on the thyristors. The decoder can be implemented on integrated circuits series 530.
