Tips: The working principle of bottle jack
The bottle jack works by the hydraulic principle, namely the principle of Pascal's law. It consists of a oil tank, two pressure cylinders of different sizes, a rocker and a closing needle valve. When working, lift the small piston by rocker to suck the oil into the small pressure cylinder, and when the small piston is depressed, the oil is pressed into the big pressure cylinder. Through the control of the two valves, the pressure of the oil by the small piston is transmitted to the big piston to lift the weight. The small piston continuously reciprocates to push the heavy object to a certain height. After the work is completed, open the closing needle valve to connect the big pressure cylinder with the oil tank. At this time, as long as a little pressure is applied to the big piston, the big piston can drop down and the oil will return to the oil tank.
