Claims

[Scope of utility model registration request]

A piston [or plunger] that slides inside the cylinder as the shaft rotates, and an auxiliary piston that does not slide with the rotation of the shaft but is provided in a sleeve shape relative to the piston [or plunger] and slides by hydraulic pressure. By placing the piston [or the auxiliary plunger] inside the cylinder and having both pistons [or the plunger] slide inside the cylinder, even if the rotational speed of the shaft or the supply flow rate fluctuates within a limited range, A variable displacement hydraulic pump that sucks in all the supplied flow, subtracts the leakage amount, pressurizes the remaining flow, and then discharges it.
