PURPOSE: A direct-acting warm-heartedness pressure driver for improving the efficiency of the fluid pressure energy is provided to stably supply the flow rate of the fluid within system while selectively opening closing the reservoir by a check valve. CONSTITUTION: A direct-acting warm-heartedness pressure driver includes a pump(120), a closed type hydraulic device(170), a first fluid path, a second fluid path, a third fluid path, an oil reservoir, and a first check valve. The pump alternates the driving source to the forward direction and reverse direction and two way pump transfers the fluid. The closed type hydraulic device is formed in the first check valve. The second fluid path interlinks the reverse direction outlet and the second through hole of the pump. |
