working principle:

The hydraulic jack is based on the principles of Pascal's law. It consists of fuel tanks, different sizes of two pressure cylinders, rocker and close the needle valve and other parts of the composition. When working, lift the small piston to suck the oil into the small pressure cylinder, and press the small piston when the oil into the large pressure cylinder. Through the control of the two valves, the small piston of the oil pressure to the large piston, the heavy objects up. Small piston constantly reciprocating action, you can put the weight to a certain height. Work is completed, open and close the needle valve, so that large pressure cylinder and tank connected. At this time, as long as the big piston on a little pressure, the big piston can fall, the oil back to the tank
