Preferably, described fluid level control valve comprises the valve body that is installed on described oil storage tank top, described oil storage tank is stretched out in the upper end of described valve body, described oil storage tank is stretched in the lower end of described valve body, in described valve body, be provided with a cavity, in described cavity, be slidably fitted with spool, one end of described spool is provided with sealing surface and matches with sealing surface in described valve body and forms seal interface, the both sides of described seal interface are respectively arranged with suction port and air outlet, the other end of described spool is fixedly connected with guide rod, described guide rod stretches out described cavity and is connected with a float, described float is positioned at described oil storage tank.
Preferably, described valve body comprises upper body and the lower body being together by a threaded connection.
Preferably, described air outlet is connected with the pipe of collaborating, described in collaborate pipe connecting engine crankcase.
Preferably, described sucker of supercharger is S shape bending tube.
Adopted technique scheme, the beneficial effects of the utility model are: use after pressurized machine protective gear, lubricant oil is divided into two-way above pressurized machine by sucker of supercharger, and a road directly enters pressurized machine bearing place, for pressurized machine lubricates; Another part parallel connection enters the oil storage tank of pressurized machine top, and in engine operation process, machine oil constantly enters oil storage tank by oil storage tank return tube, oil storage tank enters oil storage process, along with entering the continuous supercharging of oil mass of oil storage tank, when pasta arrives float position, float rises, band movable valve plug rises, the sealing surface of spool and the sealing surface of valve body are offseted, air outlet and suction port blocking-up, now oil storage tank internal pressure rises, machine oil no longer enters oil storage tank, and oil storage process finishes.When motor runs into urgency and stops suddenly, sucker of supercharger cut fuel feeding, but pressurized machine is also running up, part machine oil in oil storage tank enters the pressurized machine turning round by oil tank return tube, now float declines, band movable valve plug declines, the sealing surface of spool and the sealing surface of valve body are departed from, air outlet is communicated with suction port, under the effect of gravity, the machine oil storing in oil storage tank just can accelerate dirty, continuation supplies the lubricant oil of a period of time with protection pressurized machine to exhaust-gas turbocharger, pressurized machine bearing is lubricated with cooling, prevent that axle sleeve interlock and the generation of burning machine oil situation from appearring in pressurized machine, play and extend the pressurized machine effect in working life.
Because valve body comprises upper body and the lower body being together by a threaded connection, can control fuel head by adjusting the length of valve cavity, guarantee to store applicable oil mass.
Because air outlet is connected with the pipe of collaborating, the crankcase of the pipe connecting engine of collaborating, when valve seal does not sternly occur lubricating oil leakage, the machine oil of leakage can directly flow back to crankcase.
Because sucker of supercharger is S shape bending tube, can effectively prevent that machine oil in oil storage tank from flowing backwards back in sucker of supercharger, guarantee the pressurized machine that timely lubrication and cooling is turning round, prevent that pressurized machine from burning out.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Fig. 1 and Fig. 2 are common, pressurized machine protective gear, comprises the oil storage tank 1 that is installed on pressurized machine top, and the bottom of oil storage tank 1 is connected with an oil storage tank return tube 2, and oil storage tank return tube 2 is in parallel with sucker of supercharger 3; The top of oil storage tank 1 is provided with a fluid level control valve 4.Fluid level control valve 4 can adopt mechanical liquid level control valve, also can adopt electronic type fluid level control valve.
Below the detailed explanation of fluid level control valve to adopting in the present embodiment:
Fluid level control valve 4 comprises the valve body 5 that is installed on oil storage tank 1 top, oil storage tank 1 is stretched out in the upper end of valve body 5, oil storage tank 1 is stretched in the lower end of valve body 5, in valve body 5, be provided with a cavity, in cavity, be slidably fitted with spool 6, one end of spool 6 is provided with primary sealing area 61 and matches with secondary sealing area 51 in valve body 5 and forms seal interface, the both sides of seal interface are respectively arranged with suction port 7 and air outlet 8, the other end of spool 6 is fixedly connected with guide rod 9, guide rod 9 stretches out cavity and is connected with a float 10, and float 10 is positioned at oil storage tank 1.
