Abstract:
PROBLEM TO BE SOLVED: To solve a problem that a filer cannot be easily cleaned.SOLUTION: This hydraulic unit 1 of the present invention comprises a pump 6 which sucks oil supplied from an oil tank 3 from an intake port 8, and discharges it from a discharge port 7, a motor 5 which is switchable between forward rotation and reverse rotation and drives the pump 6, and a control part which controls the motor 5. A strainer 10 in which the oil before being supplied to the pump 6 passes toward an internal peripheral side from an external peripheral side when the motor 5 is controlled so as to forwardly rotate is arranged in the oil tank 3. In the hydraulic unit 1, the pump 6 discharges the oil, which is sucked from the discharge port 7, from the intake port 8 when the motor 5 is controlled so as to reversely rotate, the discharged oil is thereby supplied to the oil tank 3, and passes in the strainer 10 toward the external peripheral side from the internal peripheral side, and thus the strainer 10 is cleaned.SELECTED DRAWING: Figure 4
