An oil booster is provided to simplify structure of the oil booster using a signal cylinder and vary a pressure of the oil pressure by changing a hydraulic pressure or exchanging a component. An oil booster includes a housing member(10), a piston member(20), a first packing member(30), and a second packing member(40). The housing member includes a hollow pipe(11), a high pressure port(13), a piston port(15), and an ultrahigh pressure port(17). The hollow pipe is formed in the housing member. The high pressure port is formed at one side of the hollow pipe. The piston port is formed at the other side of the hollow pipe to reciprocate a portion of the piston. The ultrahigh pressure port is spaced a predetermined distance from the piston port. The piston member is inserted into the hollow pipe. The first packing member is coupled to an oil reservoir adjacent to the high pressure port. The second packing member is coupled between the ultrahigh pressure port and the piston port. |
