(ON) in the case of, as described above, check-valves 31 is forced valve opening and allows oil pressure from oil circuit 27 to the oil of oil circuit 26 the namely the 1st
The adverse current of press pump 10.
Electromagnetic opening and closing valve 44 is equipped between oil circuit 26 and oil circuit 24, by that by the valve opening of electromagnetic opening and closing valve 44, can make
The oil pressure of oil circuit 26 is drained to oil circuit 24 and discharges the oil pressure of oil circuit 26.By oil circuit 26, electromagnetic opening and closing valve 44, the row of composition of oil circuit 24
Let out mechanism.
Controller 50 be using sensor detect the inlet temperature of such as supply, booster 5 downstream supply pressure
Power etc., it is as described below as, the supply gas pressure that is detected based on this, inlet temperature etc., to the 1st oil pressure pump 10, the 2nd oil pressure pump 11,
The work of electromagnetic switching valve 41,42, electromagnetic opening and closing valve 44 etc. carries out electrical control.In addition, also there is controller 50 to use the confession
Parameter beyond atmospheric pressure and inlet temperature is opened and closed to the 1st oil pressure pump 10, the 2nd oil pressure pump 11, electromagnetic switching valve 41,42, electromagnetism
The situation that the work of the grade of valve 44 is controlled.
Next, the work to the booster excess power retracting device of this internal combustion engine illustrates.During engine starting,
Controller 50 makes the electromagnetic switching valve 41 of the 1st check valve mechanism 30 shown in Fig. 2 work and close (OFF) the 1st check valve mechanism
30 non-return removing function, and the electromagnetic switching valve 42 of the 2nd check valve mechanism 35 is worked and is closed (OFF) the 2nd check-valves
The non-return removing function of mechanism 35.Moreover, make the valve closing of electromagnetic opening and closing valve 44.
Therefore, check-valves 31 forbid oil pressure from oil circuit 22 to oil circuit 21 adverse current, check-valves 36 forbid oil pressure from oil circuit 27 to
The adverse current of oil circuit 26.Then, controller 50 makes the rotation driving of motor 52, and the oil pressure needed for starting is produced using oil pressure pump 53, and
It is fed to the control loop of Work machine 51.Now, check-valves 32 is also preventing oil pressure from oil circuit 23 to the adverse current of oil circuit 22.
Then, to during load 35% when internal combustion engine is underload, for example since starting, controller 50 makes the 1st to stop
The electromagnetic switching valve 41 for returning valve system 30 works and closes the non-return removing function of (OFF) the 1st check valve mechanism 30, and makes the
The electromagnetic switching valve 42 of 2 check valve mechanisms 35 works and opens the non-return removing function of (ON) the 2nd check valve mechanism 35.Therefore,
Check-valves 36 is forced valve opening, and allows oil pressure from oil circuit 27 to the adverse current of oil circuit 26.
Then, oil pressure caused by the 2nd oil pressure pump 11 sequentially via oil circuit 21, check-valves 31, oil circuit 22, check-valves 32,
Oil circuit 23 supplies to the control loop of Work machine 51.At the same time, oil pressure caused by the 2nd oil pressure pump 11 is sequentially via oil circuit
21st, check-valves 31, oil circuit 22, oil circuit 27, the check-valves 36 for being forced valve opening, ejiction opening 10a from oil circuit 26 to the 1st oil pressure pump 10
Supply, and assist the rotation of the 1st oil pressure pump 10.
That is, assist to be linked to the booster 5 of the 1st oil pressure pump 10 using oil pressure caused by the 2nd oil pressure pump 11
Rotation, and rightly carry out supercharging when easily generation is pressurized the underload of deficiency.In addition, the 1st oil pressure pump 10 of variable capacity type
By its changeable mechanism, even utilizing the adverse current of the oil pressure from ejiction opening 10a also can rotate forward booster 5.
The inlet temperature of supply detected by the reading sensor of controller 50, the supply path in the downstream of booster 5
Supply gas pressure etc..Moreover, it is to be set in controller 50 according to each load of internal combustion engine to assist the power needed for booster 5
It is fixed.Controller 50 is based on the supply gas pressure, inlet temperature etc., the capacity of the 1st oil pressure pump 10 of variable capacity type is suitably changed,
And control the power for assisting booster 5.
Then, when internal combustion engine is middle load, during such as load 35~50%, controller 50 makes the shown in Fig. 3 the 1st to stop
The electromagnetic switching valve 41 for returning valve system 30 works and closes the non-return removing function of (OFF) the 1st check valve mechanism 30, and makes electricity
The valve opening of magnetic open and close valve 44.
After the valve opening of electromagnetic opening and closing valve 44, oil pressure caused by the 1st oil pressure pump will be from oil circuit 26 via electromagnetic opening and closing valve
44 drain and are released to oil circuit 24, so pressure step-down, without flowing to the higher oil circuit 27 of pressure by check-valves 36.
In this case, so-called no-load running, but in order that system are turned into by the 1st oil pressure pump 10 of the rotation driving of booster 5
Cooling can spray the oil pressure of certain pressure.
On the other hand, oil pressure caused by the 2nd oil pressure pump 11 via oil circuit 21, check-valves 31, oil circuit 22, check-valves 32,
Oil circuit 23 supplies to the control loop of Work machine 51.Although oil pressure caused by the 2nd oil pressure pump 11 is of a relatively high, due to control
Device 50 processed makes the electromagnetic switching valve 41 of the 1st check valve mechanism 30 shown in Fig. 3 work and closed (OFF) the 1st check valve mechanism
30 non-return removing function, therefore, by the normal check function of check-valves 36, the oil pressure of oil circuit 27 will not pass through check-valves
36 flow to oil circuit 26.
So, when internal combustion engine is middle load, during such as load 35~50%, the 1st oil pressure pump 10 turns into without negative
Lotus operates, and only supplies oil pressure to Work machine 51 using the 2nd oil pressure pump 11.In addition, must be by the 1st of the side of booster 5 the
In the case of oil pressure gearing cut-out between oil pressure pump 10 and the 2nd oil pressure pump 11 of the side of engine 1, such as when emergent stopping,
Also carry out working with the identical.
When then, when internal combustion engine is high load capacity, such as load more than 50%, controller 50 makes the 1st non-return shown in Fig. 4
The electromagnetic switching valve 41 of valve system 30 works and opens the non-return removing function of (ON) the 1st check valve mechanism 30, and makes the 2nd to stop
The electromagnetic switching valve 42 for returning valve system 35 works and closes the non-return removing function of (OFF) the 2nd check valve mechanism 35.Moreover, make
The valve closing of electromagnetic opening and closing valve 44.
Therefore, the check-valves 31 of the 1st check valve mechanism 30 is forced valve opening, and allows oil pressure from oil circuit 22 to oil circuit 21
It is exactly the adverse current of the 2nd oil pressure pump 11.Moreover, the check-valves 36 of the 2nd check valve mechanism 35 allows also by normal check function
Oil pressure flows to oil circuit 27 from oil circuit 26.
Therefore, oil pressure caused by the 1st oil pressure pump 10 sequentially via oil circuit 26, check-valves 36, oil circuit 27, check-valves 32,
Oil circuit 23 supplies to the control loop of Work machine 51., can be from the 1st oil pressure pump 10 in the case of such as load more than 50%
Supply whole oil pressure needed for Work machine 51.
Moreover, when engine 1 is high load capacity, the 1st oil pressure pump 10 can produce such as 2 of oil pressure needed for Work machine 51
Times or so oil pressure.Therefore, oil pressure caused by the 1st oil pressure pump 10 is sequentially via oil circuit 26, check-valves 36, oil circuit 27, oil circuit
22nd, check-valves 31, oil circuit 21 also supply to the ejiction opening 11a of the 2nd oil pressure pump 11, and assist the rotation of the 2nd oil pressure pump 11.
That is, assist to be linked with the engine 1 of the 2nd oil pressure pump 11 using oil pressure caused by the 1st oil pressure pump 10
Rotation.Controller 50 fits the capacity of the 1st oil pressure pump 10 based on the maximum power set in advance that can be reclaimed from booster 5
Work as change, thus adjust the oil hydraulic power reclaimed from booster 5.
Can also be as shown in figure 5, the 2nd oil pressure pump 11 to be linked to the motor that rotary power is produced in the same manner as engine
(power source) 54 rather than it is linked to engine.As the motor 54, such as use induction conductivity.Induction conductivity turns
Speed is determined by the frequency of power system, is rotated all the time with fixed rotate.Therefore, do not need especially to utilize the oil sector
20 grades carry out the rotating speed control of motor 54.
Then, from the remaining oil pressure of the 1st oil pressure pump 10 supply when being high load capacity using engine, by making motor
54 are used as generator operation, and produce electric power, and by the power supply to power system.Electric power needed for ship etc. is typically
Using obtained by the electrical power generators of engine rotation driving, therefore result can seek the fuel efficiency of engine to improve.This
Outside, when engine is underload, middle load when, high load capacity when internal combustion engine booster excess power retracting device work with
The situation of the engine 1 is identical, therefore omits the description.
Can also be as shown in fig. 6, with booster 5 side by side across flow rate regulating valve 56 on the exhaust pathway 4 of engine
Power turbine 55 is arranged, and links the 1st oil pressure pump 10 in the power turbine 55.In this case, when engine is middle load and
The work of the booster excess power retracting device of internal combustion engine during high load capacity is identical with the situation of the engine 1.But
On construction, when engine is underload, can not directly it be assisted via the 1st oil pressure pump 10 using oil pressure caused by the 2nd oil pressure pump 11
Help the rotation of booster 5.It is identical with the situation of the booster 5 in addition, therefore omit the description.
Moreover, the 1st oil pressure pump may not be variable capacity type, or fixed capacity type.If set to fixed hold
Amount type, then significantly saving spatially can be sought.But in the case where the 1st oil pressure pump is set into fixed capacity type, nothing
Method rotates forward pump using the adverse current of the oil pressure from ejiction opening, therefore can not be in underload under the composition of the oil sector 20
When assist booster 5.
When therefore, in order to when engine 1 is underload, middle load, high load capacity when carry out and the supercharging of the internal combustion engine
Device excess power retracting device identical is worked, it is necessary to mouth can be also included from normal oil pressure in adverse current with oil pressure and is flowed into pump
Mode to the carry out part change such as composition of oil sector 20.In addition with the 2nd oil pressure pump 10 of the variable capacity type
Situation it is identical, therefore omit the description.
As described above, in the booster excess power retracting device of this internal combustion engine, the 1st oil pressure pump 10 is linked to booster
5 or power turbine 55, oil pressure is produced by the booster 5 or the rotation driving of power turbine 55, the 1st oil pressure pump 10 can be to hair
The Work machine 51 of motivation 1 directly feeds oil pressure not via the engine 1 as power source or the ground of motor 52.
Moreover, conventional supplies the 2nd oil of oil pressure via oil sector by the power source rotation driving to Work machine
Press pump is when internal combustion engine is high load capacity etc., it is necessary to the oil pressure needed for being worked to Work machine large supply.Therefore, the 2nd oil pressure pump
Required capacity or number of units is determined according to its maximum spray volume.However, the booster excess power in this internal combustion engine reclaims
In device, especially when needing the high load capacity of maximum spray volume, even if also still having using exhaust energy rotation driving booster 5
Residue, therefore the 1st oil pressure pump 10 directly supplies oil pressure via the 2nd oil circuit to Work machine 51.
Therefore, it is possible to make capacity needed for the 2nd oil pressure pump 11 or number of units subtract by the oil pressure amount supplied from the 1st oil pressure pump 10
It is few, so as to seek into this Xiao Minus.Moreover, the power loss that can also make accordingly to increase with spray volume is along with the 2nd oil
The reduction of capacity or number of units needed for press pump 11 and reduce.
Should most be concerned with herein, can by the booster excess power retracting device of conventional internal combustion engine it is required with
Engine crankshaft link booster excess power retracting device oil pressure pump exclude, and can will because of the oil pressure pump and caused by
Power loss all excludes.Moreover, conventional, the 1st oil pressure pump can be assisted to be linked to needed for the oil pressure pump of engine crankshaft
Oil sector all exclude.
Therefore, the oil sector of the booster excess power retracting device of conventional internal combustion engine is formed without repetition equipment
Oil pressure pump, valve class, safety device, pipe arrangement etc., and the significantly reduction of cost can be sought.Moreover, it is crisscross be equipped with it is multiple
Around the internal combustion engine of subsidiary engine class, the weight without the excess power retracting device and the oil sector of internal combustion engine device of booster
Compounding is put, and can seek the facilitation in design.
Moreover, as described above, when engine 1 is high load capacity, the 1st oil pressure pump 10 can produce oil pressure needed for Work machine
E.g., from about 2 times of oil pressure.In the booster excess power retracting device of this internal combustion engine, controller 50 is by the during high load capacity the 1st
A part for oil pressure supplies to Work machine 51 caused by oil pressure pump 10, and by oil pressure caused by the 1st oil pressure pump 10
Remainder supplies to the 2nd oil pressure pump 11, therefore, it is possible to start not because of oil pressure pump during high load capacity with producing power loss
The remaining exhaust energy of machine 1 is effectively utilized as the oil pressure needed for Work machine 51, and can utilize the 1st oil pressure pump 10
Caused oil pressure assists to be linked with the rotation of the power source of the 2nd oil pressure pump 11.
Thus, for example directly fuel efficiency can be sought to improve in the case where power source is engine 1, moreover, dynamic
In the case that power source is motor 52, is generated electricity by making it as generator operation, internal combustion engine as a result can be sought whole
The fuel efficiency of body improves.
In addition, the booster excess power retracting device of the internal combustion engine is only one, being capable of the purport based on the present invention
Various change is carried out, these changes are not excluded outside the scope of the present invention.Moreover, the booster in the internal combustion engine remains
In remaining power recovery apparatus, load is set to underload below 35%, load 35~50% is set to middle load, and by load
More than 50% is set to high load capacity, but only one, and it can be different according to the species of internal combustion engine or Land use systems etc., do not limit
In these.
