Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the present invention to be described.
The structure of the motor oil-controlling device of the present embodiment is as follows:
Understand incorporated by reference to Fig. 1, the motor oil-controlling device 2 of the present embodiment comprises inlet pipe connection 21, air pressure adjusting device 22, control switch 23, pneumatic vacuum pump 24 and the transition flexible pipe 25 be connected successively.This inlet pipe connection 21 is for passing into pressurized air, this air pressure adjusting device 22 is for regulating compressed-air actuated air pressure, this control switch 23 is for controlling connection and the shutoff of pipeline between this air pressure adjusting device 22 and this pneumatic vacuum pump 24, and this pneumatic vacuum pump 24 for vacuumizing by this transition flexible pipe 25 under compressed-air actuated drive.
In the motor oil-controlling device 2 of the present embodiment, this pneumatic vacuum pump 24 can also replace with the extraction pump of other kind.In addition, this inlet pipe connection 21, this air pressure adjusting device 22 and this control switch 23 are together to form vacuum-ness regulator, by controlling the degree of vacuum of the fuel reserve tank of this motor 5 of Flow-rate adjustment of this pneumatic vacuum pump 24.When this pneumatic vacuum pump 24 uses the extraction pump of other kind to replace, this vacuum-ness regulator also can correspondingly change, such as, when using electric vacuum pump, this vacuum-ness regulator can be just voltage regulating device, just can regulate electric vacuum pump rotational speed by the concrete numerical value of control voltage, and then reach the object changing degree of vacuum.
Installation and the use principle of the motor oil-controlling device of the present embodiment are as follows:
During installation, composition graphs 1 and Fig. 2 please understand simultaneously, this inlet pipe connection 21 is connected with compressed air line 1, this transition flexible pipe 25 is connected with motor breathing pipe 3.
