It is provided with asphalt channel 323 on interior bottom case 32, is connected to the first shoe cream room 310 and the second shoe cream room 320.In oil
It is provided with vent control valve 5 in paths 323, is used to control the switch of asphalt channel 323.
When the engine is working, oil pump 4 works, and the oil in oil sump 3 is conveyed to cylinder cap oil return pipe by fuel feed pump 11
21.First oil return pipe 14 is main oil return pipe, oil return pipe supplemented by the second oil return pipe 15.Major part or a large amount of in cylinder cap oil return pipe 21
Oil be back in the first shoe cream room 310 by the first oil return pipe 14, a small amount of oil of another part in cylinder cap oil return pipe 21 is logical
The second oil return pipe 15 is crossed to be back in the second shoe cream room 320.
When vent control valve 5 is opened, the oil in the first shoe cream room 310 flows into the second shoe cream room through asphalt channel 323 again
In 320.Oil in oil sump 3 is recycled through oil pump 4 to be exported, then is flowed back benefit through the first oil return pipe 14 and the second oil return pipe 15 respectively
With.
When vent control valve 5 is closed, the first shoe cream room 310 and the second shoe cream room 320 are mutually indepedent, and oil circuit closing is not flowed
Logical, only the oil of the second shoe cream room 320 is exported by oil pump 4.And when vent control valve 5 is closed, the first oil return pipe 14 and the
Two oil return pipes 15 are also respectively to 320 oil return of the first shoe cream room 310 and the second shoe cream room, and the oil in the second shoe cream room 320 can quilt
Oil pump 4 persistently exports, and the liquid level in the first shoe cream room 310 can be made to be higher than the liquid level in the second shoe cream room 320.
Since the liquid level in the first shoe cream room 310 is higher than the liquid level in the second shoe cream room 320, opened in vent control valve 5
When, the oil in the first shoe cream room 310 more can be flowed into rapidly in the second shoe cream room 320.
Since the liquid level in the first shoe cream room 310 is higher than the liquid level in the second shoe cream room 320, in the first shoe cream room 310
Oil is enclosed in the surrounding of the second shoe cream room 320, to be conducive to keep the temperature the oil in the second shoe cream room 320.
When internal combustion engine or engine start, since oil temperature is lower, it is unfavorable for quickly flowing, influences oil consumption, at this time preferably
Asphalt channel 323 is closed by vent control valve 5 in ground, and the machine oil only in the second shoe cream room 320 or lubricating oil are flowed at this time
Logical heating, since the amount of work machine oil is reduced, oil temperature can faster promote temperature, reduce warming-up speed.Meanwhile first stores up
Fully wrapped around firmly the second shoe cream room of the machine oil of oil pocket storage, can play insulation effect, the temperature of the second shoe cream room is accelerated to rise.
Furthermore it is also possible to the oil temperature according to oil temperature come the open and close of control channel control valve 5, in the second shoe cream room
When lower than preset temperature, vent control valve 5 closes asphalt channel 323, when the oil temperature in the second shoe cream room is greater than preset temperature,
Vent control valve 5 opens asphalt channel 323.
Preferably, the first drain oil 3110 is provided in the bottom of outer bottom case 31, in interior bottom case as shown in Fig. 1 and Fig. 4-5
32 bottom is provided with the second drain oil 3210.First drain oil 3110 is located at the lower section of the second drain oil 3210.It is put first
Control valve 6 of draining the oil is connected between oilhole 3110 and the second drain oil 3210.
Control valve 6 of draining the oil can individually open the second drain oil 3210, can also open 3210 He of the second drain oil simultaneously
First drain oil 3110.
When control valve 6 of draining the oil individually opens the second drain oil 3210, the machine oil in the second shoe cream room 320 can be put through second
Oilhole 3210 flows into the first shoe cream room 310.
When draining the oil control valve 6 while opening the second drain oil 3210 and the first drain oil 3110, in the second shoe cream room 320
Machine oil and the first shoe cream room 310 in machine oil can through the first drain oil 3110 flow out oil sump 3, fast and easy replace machine oil.
Preferably, as shown in Figure 1-3, vent control valve 5 is temperature control valve.
Wherein, when oil temperature≤T1 in the second shoe cream room 320, vent control valve 5 closes asphalt channel 323.Second
When oil temperature > T1 in shoe cream room 320, vent control valve 5 opens asphalt channel 323.
T1 is preset oil temperature, be can be set as needed.For example, T1 can between 50 DEG C -90 DEG C value.
As oil temperature≤T1 in the second shoe cream room 320, vent control valve 5 closes asphalt channel 323, and at this time only second
Machine oil in shoe cream room 320 is exported by oil pump 4.First oil return pipe 14 and the second oil return pipe 15 are respectively to the first shoe cream room 310
With 320 oil return of the second shoe cream room so that liquid level in the first shoe cream room 310 is higher than the liquid level in the second shoe cream room 320.Due to work
The amount for making machine oil is reduced, and oil temperature can faster promote temperature, reduces warming-up speed.Meanwhile first shoe cream room storage machine
Fully wrapped around firmly the second shoe cream room of oil, can play insulation effect, the temperature of the second shoe cream room is accelerated to rise.
As the oil temperature > T1 in the second shoe cream room 320, vent control valve 5 opens asphalt channel 323, at this point, the first storage
Machine oil in oil pocket 310 can flow rapidly into the second shoe cream room 320, improve machine oil velocity of liquid assets, and effective machine oil circulation is handed over
Machine oil high-temperature temperature can be reduced by changing, and guarantee the service life of machine oil.

Main valve lid 51 is connected to one end of slide bar 53, and is located in the second shoe cream room 320, and secondary valve deck 52 is connected to slide bar 53
The other end, and be located at the first shoe cream room 310 in.
It is connected between main valve lid 51 and interior bottom case 32 for driving main valve lid 51 towards moving in the second shoe cream room 320
Temperature sensing spring 511.When oil temperature≤T1 in the second shoe cream room 320, the pretightning force of temperature sensing spring 511 is F1, in the second storage
When oil temperature > T1 in oil pocket 320, the pretightning force of temperature sensing spring 511 is F2.It is provided between secondary valve deck 52 and interior bottom case 32
For driving secondary valve deck 52 towards the valve deck driving spring 521 moved in the first shoe cream room 310, valve deck driving spring 521 it is pre-
Clamp force is F3.Wherein, F1 < F3 < F2.
When oil temperature≤T1 in the second shoe cream room 320, due to F3 > F1, valve deck driving spring 521 overcomes temperature-sensitive bullet
The active force of spring 511 drives main valve lid 51, slide bar 53 and secondary valve deck 52 mobile towards the direction of the first shoe cream room 310, finally makes
Winner's valve deck 51 seals up asphalt channel 323.
Specifically, sealing ring 324 is provided on the interior bottom case side plate 322 of interior bottom case 32, sealing ring 324 is located at the second storage
In oil pocket 320, sealing ring 324 is looped around the exit of asphalt channel 323.It is adjacent to when on sealing ring 324 in main valve lid 51, it is main
Valve deck 51 seals up asphalt channel 323.
When oil temperature > T1 in the second shoe cream room 320, due to F2 > F3, temperature sensing spring 511 overcomes valve deck driving spring
521 active force drives main valve lid 51, slide bar 53 and secondary valve deck 52 mobile towards the direction of the second shoe cream room 310, main valve lid 51
It leaves when on sealing ring 324, main valve lid 51 opens asphalt channel 323.
Preferably, temperature sensing spring 511 is memory alloy spring, is bimetallic temperature sensing spring, and shape memory conjunction is utilized
The double-pass memory effect of gold, is a kind of temperature-sensitive driving element that variation with temperature can voluntarily stretch.
Preferably, as shown in figures 1 and 3, vent control valve 5 includes the valve chest 54 and and valve with hollow cavity 540
