[0049] In the first manner, the filling pipe 32 includes a first branch pipe 321 and a second branch pipe 322 , the two branch pipes are contained, and there is a position adjustment and locking mechanism therebetween.
[0050] In the second manner, the filling pipe 32 is a telescopic corrugated pipe, and the telescopic corrugated pipe is connected with the stretching device and the position locking mechanism.
[0051] The filling pipe 32 may also be a fixed-length pipe.
[0052] According to the above method, a device for adjusting the liquid level of the automobile brake fluid oil pot with a siphon is designed and manufactured, and the device includes:
[0053] A filling gun 30, the filling gun 30 has a sealing structure matching the spout 41 of the brake fluid oiler 40;
[0054]A filling pipe 32 extends from the filling gun 30 and is placed inside the brake fluid oiler 40 during operation;
[0055] A brake oil input pipeline 21, on which a first valve 61 is arranged, afte...

The invention discloses a method and a device for using a siphon to adjust the height of the fluid level of a braking fluid oil pot of a vehicle; the filling tube of a filling gun is a tube with adjustable length or a tube with fixed length; a first valve is arranged on the input pipeline of the braking fluid; a first oil passage and a second oil passage which are mutually communicated are connected behind the valve; the second oil passage is connected with a second valve which is arranged at the height lower than the opening of the filling tube and has enough height difference; when the filling quality of the braking fluid is qualified, an operator turns off the first valve and turns on the second valve, then the filling tube, the filling gun, the first oil passage and the second oil passage form a siphon pipeline at the moment; the braking fluid flows out from the braking fluid oil pot and is drained from an oil outlet at last; when the fluid level of the braking fluid in the oil potis reduced to the opening of the filling tube, the siphon phenomenon is damaged and the siphon is stopped; the working of adjusting the height of the fluid level of the braking fluid oil pot of the vehicle is over. The invention is simple to be operated and can ensure the working quality.
Description
technical field [0001] The invention relates to a method and a device for filling an automobile brake fluid, in particular to a method and a device for adjusting the liquid level of an automobile brake fluid pot by means of a siphon. Background technique [0002] Earlier brake fluid filling was manually filled. The specific method is: one person continuously steps on the brake pedal of the car back and forth in the cab, uses the brake pump of the car to pressurize the brake fluid, and sends the brake fluid to the brake pipeline, while the other person Open the exhaust valve of the brake pipeline at the bottom of the car, and use the flow of brake fluid to discharge the air in the brake pipeline to achieve the purpose of removing the air from the brake pipeline. The employees in the cab still need to continuously replenish the brake fluid in the brake fluid oiler. After the operation is completed, they also need to adjust the oil level line in the brake fluid oiler so that t...
