Hydraulic jack is based on Pascal's principle works. It consists of a tank, two pressure cylinders of different sizes, rocker arms and close the needle valve consists of several parts. Work, lift the small piston oil inhalation of small pressure cylinders, when the small piston under pressure hydraulic pressure oil

Cylinder. Through the two valves of the control, the small piston of oil pressure to the piston and lift the top up. Small piston reciprocating motion constantly, you can lift the top to a certain height. After work, open close needle valve, high pressure cylinders and tanks connected.
