在に配置して成る油圧ユニツト。 An electric motor that drives a hydraulic pump that sucks in and discharges oil and a solenoid valve that controls the flow of oil that has two electromagnets are placed on the upper plate of a tank that is installed to store oil inside. An operation switch for remotely controlling the solenoid valve is placed separately from the tank, and the operation switch has a first contact that opens and closes between one electromagnet of the solenoid valve and the DC power supply side, and a first contact that opens and closes between the other electromagnet of the solenoid valve and the DC power supply side. The second opening and closing between the side
The electric motor and the DC power supply side are electrically connected via an electromagnetic switch that opens and closes the contacts when energized and de-energized, and the electromagnetic switch also opens and closes when the electromagnets of the solenoid valve are energized and de-energized by operating the operation switch. The solenoid switch and each electromagnet of the solenoid valve are electrically connected via a rectifier so that the solenoid switch and each electromagnet of the solenoid valve can be opened and closed. A hydraulic unit configured to allow current to flow from each electromagnet side of a solenoid valve to an electromagnetic switch side, and to freely block current flow from the electromagnetic switch side to each electromagnet side of a solenoid valve.
