All relays 1 to 27 of FIG. 1 correspond to the principle diagram of FIG. 2, so for clarity of the drawing, the various reference numbers in FIG. 2 not in FIG. 1 are reproduced and to understand how any of the relays 1 to 27 are connected, consider FIG. 2 is sufficient.

A line 28, which is provided with a feed circuit, which supplies a pressure medium, eg air for starting the engine under a pressure of 18 bar, feeds a pressure reducer 29, which reduces this pressure to a considerably lower value, eg 7 bar. The output circuit 30 of the pressure reducer 29 feeds via a distributor 31 controlled and fed by a control circuit 32 (so that the feed through the circuit 30 automatically takes the place of the feed with control air through the circuit 32 if the latter fails), a filter 33 and two pressure reducers 34 and 35, two circuits 36 and 37, respectively, which operate under two different pressures, the circuit 36 under a pressure P 1

Circuits 36 and 37 feed certain relays in the system, the first via a microvalve 38 for switching on and off. ■

The pressure of 1.4 bar is fed through the circuit 36 to the openings d of the relays 12, 13, 14 and 19 and to the opening e of the relay 27.

The pressure of 1.4 bar is also passed through the supply circuit 36 to an electrovalve 39 for remote control or automatic control, which either by operating a remote control button, not shown or can be actuated by a cause that triggers the automatic operation, e.g. B. a power failure, a microvalve 40 to start the remote control or automatic Control, which is operated when you switch from the local control to the remote control or the automatic Wants to override control, a micro-valve 41 provided with a push button for local control, a microvalve 42 also provided with a push button to restore operational readiness from safety organs and a drain microvalve 43 supplied.

B. in the fuel feed circuit and this opens or closes), a distributor 50, which controls the prelubrication pump and the drainage, and a distributor 51 connected to the distributor 50.

A push-button microvalve 52 for stopping the engine on the spot is connected to port e of relay 21 and to port e of relay 3, to port c of relay 27 and to port a of relay 8. This micro-valve enables the engine to be switched off directly at the point of the system.

A microvalve 53 for remote shutdown is connected to the openings c and b of the relay 8. This micro-valve enables the engine to be switched off remotely.

A distributor 54 is connected to the distributor 50 and the openings ω and b of the relay 8. This distributor is intended to prevent the prelubrication pump from working if the engine is switched off by the microvalve 53 for remote shutdown.

The system also contains three pressure sensitive switches, one of which, 55, is an alarm device to display what did not take place

. Start-up controls, is connected to the opening c of the relay 7, while the second switch 56 to display the location-controlled shutdown with the opening c of the relay 8 and the microvalve 53 and the third switch 57 to display the non-operational readiness of the safety organs with the opening d of the Relay 2 and the opening c of the relay 25 and also with the opening α of the relay 10 is connected.

11 is a regeneration relay which uses an intermediate control device (the aforesaid first intermediate control device) forms and the starting control pulses supplied by the microvalve 41 receives relays 9 and 10 or via solenoid valve 39;

is a storage relay (called storage device above), which is controlled by the regeneration relay 11 and fed by the pressure P 1 (1.4 bar);

13 is an intermediate control device (called a second intermediate control device above) which is controlled by the memory 12 and the relays 5, 15, 16 and 17 supplies a control pressure.

This relay device, which is fed by the feed circuit under pressure P 1 (1.4 bar), is preloaded with pressure P 2 (0.8 bar), so that it only tilts when it reaches a pressure P 2 of 1 from storage relay 12. 4 bar receives, ie it only tilts when the storage relay 12 is ready for operation;

is a delay device (called a second delay device above) having a Constriction 60 and a storage space 61, which creates a delay of 10 seconds and controls memory 12;

is a relay which controls the valve for the starting air via the distributor 48 (control device above named for the valve for the starting air);

This relay controls relays 15 and 16;

is an auxiliary relay controlling relay 14;

is a relay which is controlled by the memory 12 and feeds the next relay 20;

sends a pressure from the relay 19 to the pressure medium-controlled organ for fuel supply Via the distributor 49 (the relays 19 and 20 form the above-mentioned control device of the pressure medium-controlled organ for fuel supply; is a storage area (above storage device called), which is controlled by the relay 10 and by the microvalves 52 or 53 and controls the storage device;

22, 23 and 24 form a relay combination for controlling the memory 26;

is a relay that signals the occurrence of the alarm "Safety organs not ready for operation" controls or prevents by the pressure sensitive switch 57; is a through the microvalve to restore the operational readiness of the security organs 42 controlled memory;

is a relay which is controlled by the micro valve 40 (via relay 8) and the micro valve 52 controls for the on-the-spot parking by making it ineffective if the system is in the position for »automatic control«.

The system enables the control of the prelubrication pump, the pressure medium-controlled device for fuel supply and the pump for supplying the starting air by means of distributors 50, 49 and 48, respectively;

The sequential control of this pump, the valve and the pressure medium-controlled organ normally causes the working of the engine, which is determined by the appearance of the oil pressure in the lubrication circuit will.

The starting sequence of the engine is as follows: _g

Pressurization of the pressure medium-controlled organ for fuel supply and simultaneous Actuation of the prelubrication pump;

10 seconds later, the prelubrication pump is switched off and the valve is opened at the same time the starting air;

10 seconds later, the valve for the starting air closes and the pressure medium-controlled organ for the fuel supply to the outlet.

If the engine starts before the end of the second 10 second period above, it will immediately Valve for the starting air closed, and the pressure medium-controlled organ for fuel supply is under Pressure held.

This sequence, which corresponds to the normal starting of the engine, is activated by pressing one of the Microvalves 41 or 39 generated, which a starting control pulse in the manner described below Feed the relay 9 directly or indirectly.

Switching to local control takes place by pressing the microvalve 41 (assuming is that the microvalve 40 is in the position for local operation).

When the microvalve 40 is in the position for automatic operation, actuation of the Push button of the local manual starting microvalve 41 has no effect. The motor can only be done by remote control or automatic control, e.g. B. in the event of a power failure are set, the actuation for commissioning then being transmitted by the microvalve 39 will.

The on-site shutdown microvalve 52 enables either the engine to be shut down, or to interrupt the sequence of events in any reached state. It also allows the Restoring the operational readiness of the storage relay 26.

If one of the safety devices 45, 46 or 47 responds when the engine is running and so the shutdown of the engine, it is impossible to start another starting sequence without first using the To press the push button of the microvalve 52.

The above system works as follows:

Manual cranking: with microvalve 40 in the local operation position, press to the microvalve 41 for local operation, a start-up pulse being sent to the relay 9. This pulse goes through the relay 9, which is in the position for local control, because it is the Microvalve 40 for switching on the automatic control does not supply any excitation pressure via relay 8, and continues through relay 10 when memory 26 is operational.

The relay 10 energizes the regeneration relay 11, which makes the memory 12 ready for operation (the relay only tilts when the engine is already running, ie when the safety devices 45, 46 and 47 do not supply any pressure to its opening b ) and interrupts the storage memory 21 The pressure sent to the storage reservoir 21 acts on the opening b of the reservoir 12 and causes it to tilt.

The memory 12 actuates the regeneration relay 13, the opening b of which is loaded with 0.8 bar, as well as the relay 19 which, via the relay 20, pressurizes the pressure medium-controlled element for supplying fuel.

The openings b and d of the relay 13 are connected to the feed circuits 37 'and 36, respectively, which under

a pressure of 0.8 or 1.4 bar, so that the relay 13 can only tilt when, as already explained above, the excitation pressure is 1.4 bar, i.e., since the excitation of the accumulator 12 is 0.8 bar, only if this memory 12 is ready for operation, the production of the operational readiness of the memory 12 only takes place after the interruption of the storage memory 21.

The relay 13 sends its output pressure to the relays 15, 16 and 17 (namely to the opening α of the latter via the constriction 62 and the storage space 63). Since the relays 15 and 16 are initially caused to tilt by the relay 17, it is the relay 16 which is initially flowed through and causes the prelubrication pump to work via the distributors 50 and 51.

After 10 seconds, the relay 17 has flipped and causes the relays 15 and 16 to return to the rest position.

The prelubrication then stops and the starter air is supplied.

If the engine starts before the 10 seconds after the start of the supply of starting air, the send Safety organs 45, 46 and 47 have a safety pressure which causes the memory 12 to drop the relays 14 and 18, the pressure also acting on the relay 19, so that the pressure medium-controlled Organ for fuel supply is kept under pressure, as well as on "the relay 25 to the appearance of the Alarm display "Safety device not ready for operation" due to the effect of this same safety pressure to prevent, and finally to the memory relay 26, which drops out.

If the engine has not started 10 seconds after the start of the start-up air supply, the Delay produced by the constriction 60 and the storage space 61 causes the fall of the storage 12 by means of the relay 14, whereby the starting attempt is interrupted.

The combination of relays 14 and 18 allows memory 12 to drop out when either the engine starts in the manner indicated above, or when you press the button on the shut-off microvalve 52 presses, which causes the engine to stop during starting and the starting sequence interrupts.

It should be noted that in the case of the local control, the microvalve 40 does not apply excitation pressure to the Relays 5,1 and 9 there.

The relay 20 lifts the pressurization of the pressure medium-controlled organ for fuel supply on when the storage bin 21 is tilted.

Shutdown: The push button of the microvalve 52 is pressed, whereby the storage memory 21 is ready for use is made. The memory 21 causes the relay 18 to tilt, which is the first delay relay 14 supplies an excitation pressure, which causes the accumulator 12 to tilt, which by the relay 11 is emptied. The memory 21 also brings the relay 20 to tilt, whereby the pressure medium-controlled Organ for the fuel supply via the distributor 49 is switched to the outlet.

The combination of relays 22, 23 and 24 enables operational readiness to be restored of memory 26 when the engine is intentionally turned off and prevents restoration of the Operational readiness of this memory through the shutdown microvalve 52 when the engine is shut down was caused by the intervention of a security body. In this latter case, the memory can 26 only by the microvalve 42 to restore the operational readiness of the safety organs can be made operational again.

Automatic control or remote control: The micro-valve 40 is actuated, which relays 1,5 and makes 9 tip over.

The from which, for example, by a power failure or by pressing a remote control push button actuated solenoid valve 39 passes, as explained above, through the relay 1 and acts as before on the relay behind relay 9.

In particular, relay 11 tilts and sends a pressure of 0.8 bar to storage relay 12, which is only ready for operation when the storage memory 21 has fallen off. The then from the relay 13 received pressure is 1.4 bar and the relay toggles as explained above.

The pressure sent by the relay 13 passes through the relay 5 and makes the memory 2 ready for operation, which interrupts the pressure transmission of the relay 1, but only when the memory 12 is ready for operation is. The memory 2 remains ready for operation and sends its pressure to the relay 6, which is a so-called Relay "for information in time priority" is and the eventual alarm for that did not occur Start only at the end of the sequence of events. Relay 7 prevents this alarm from occurring, when the engine starts, as it is through the safety devices 45, 46 and 47 and the distributor 44 transmitted security pressure is energized.

It should be noted that with automatic control the system only makes a single attempt at starting.

In this case, the alarm appears to indicate that the starting process has failed and can only be triggered by a second Actuation of the shut-off microvalve 52 can be canceled after the engine has stopped.

The actuation of the push button of the storage distributor 52 interrupts the memory 2 via the of the Relay 4 controlled relay 3, except when the pressure sent by the solenoid valve 39 is still present is when this actuation occurs.

It should be noted that the accumulator 2 fed by the pressure sent by the relay 25 drops, if the shutdown of the engine is due to the response of a safety device. This will in this case, the occurrence of the failed starting alarm is avoided.

The relay 5, the opening b of which is exposed to the pressure emitted by the storage storage device 21, enables the storage device 2 to be emptied when one of the storage microvalves is actuated.

It should also be noted that the relay 8 switches the system to local control when the microvalve is opened 43 actuated, which causes the engine to be drained by means of the prelubrication pump.
