 A scroll pump comprising a fixed scroll, an orbiting scroll orbiting with a radius which is the same as the eccentric distance of an eccentric shaft to the center of the fixed scroll and contacting the fixed scroll, an inlet port formed in the middle of the upper side of the fixed scroll to influx incompressible hydraulic fluid into the scroll pump, a pressure chamber formed at the outside of the orbiting scroll to raise the pressure of the incompressible hydraulic fluid, and an outlet port formed at the side of the fixed scroll to discharge the incompressible hydraulic fluid from the scroll pump.
