The charging machine of the utility model is responded to the hydraulic pressure of braking liquid in first oil hose through pressure operated switch, cuts off the working power of charging machine automatically according to the hydraulic pressure size, the situation of effectively having avoided the braking lubricating cup to deform and damage; Simultaneously through on the wheel cylinder blow off valve, returnable bottle being set, advantage such as corresponding discharging has been avoided in braking liquid and recycle that recyclable blow off valve is discharged, has environmental protection, and cost is low, and is simple in structure, easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
In order to describe the utility model more particularly, be elaborated below in conjunction with accompanying drawing and the specific embodiment technical scheme and principle of work thereof to the utility model.
As shown in Figure 1, a kind of motor vehicle brake fluid charging machine comprises: drive motor 1, the oil pump 2 of exerting pressure, fluid reservoir 3, pressure operated switch 8, overvoltage protection relay 10, control circuit 9 and five returnable bottles 11.
The rating horsepower of drive motor 1 is 90W, and rated voltage is 220V; It links to each other with the oil pump 2 of exerting pressure through driving band 4, and then drives oil pump 2 work of exerting pressure.
Oil pump 2 one ends of exerting pressure link to each other with fluid reservoir 3 through second oil hose 5, and the other end links to each other through the pressure cover 7 of first oil hose 6 with the braking lubricating cup, and the junction of first oil hose 6 and pressure cover 7 is provided with quick coupling 12; The oil pump 2 of exerting pressure is used for braking liquid is exerted pressure.
Store braking liquid in the fluid reservoir 3, it is used to the oil pump 2 of exerting pressure braking liquid is provided.
Pressure operated switch 8 is located on first oil hose 6, and it is used for responding to first oil hose, 6 braking liquid hydraulic pressure, when braking liquid hydraulic pressure reaches or greater than 0.04 MPa, and pressure operated switch 8 starts.
