Abstract
An engine-driven oil pump has an engine, a pump unit, an oil diverting device, a manual control unit, and a remote control unit. The engine is connected to the pump unit. The oil diverting device is mounted on the pump unit and selectively pumps hydraulic oil from the pump unit into the manual control unit or the remote control unit. With the engine, the engine-driven oil pump can generate power independently instead of relying on external power supply. Besides, the electromagnetic valve of the remote control unit allows the user to remotely control the oil path of the hydraulic oil, so the user is not required to stay along the engine-driven oil pump to manually switch the oil path, and therefore the engine-driven oil pump is more efficient regarding manpower.
Claims16
An engine-driven oil pump comprising:
- an engine;
- a pump unit electrically connected to the engine and comprising
- an oil tank, wherein an oil inlet channel is located in the oil tank and an oil outlet channel is connected to the oil tank;
- and
- an oil pumping device mounted in the oil tank, being capable of pumping hydraulic oil from an inside of the oil tank into the oil outlet channel;
- an oil diverting device connecting to and communicating with the oil outlet channel, the oil diverting device comprising
- a diverting passage, wherein a tube inlet, a manual diverting opening and a remote diverting opening are formed on the diverting passage and are mutually communicating with one another;
- the tube inlet further connects and communicates to the oil outlet channel, the oil diverting device selectively closes the manual diverting opening and the oil diverting device selectively closes the remote diverting opening;
- a manual control unit connected to the manual diverting opening and the oil inlet channel, and the manual control unit comprising
- a manual unit housing, wherein two manual unit outlets are formed on the manual unit housing, a first manual unit channel and a second manual unit channel are formed in the manual unit housing, and the first manual unit channel and the second manual unit channel communicate with the two manual unit outlets respectively;
- a third manual unit channel is formed in the manual unit housing, and the third manual unit channel communicates with the manual diverting opening;
- a bore is formed in the manual unit housing, and the bore communicates with the first manual unit channel, the second manual unit channel, and the third manual unit channel;
- a manual oil regulator mounted in the bore, being capable of making the manual diverting opening communicate with any one of the two manual unit outlets;
- a remote control unit connected to the remote diverting opening and the oil inlet channel, and the remote control unit comprising
- a remote unit housing, wherein two remote unit outlets are formed on the remote unit housing, a remote unit channel is formed in the remote unit housing, and the remote unit channel communicates with the remote diverting opening and the two remote unit outlets;
- an electromagnetic valve, an inside of the electromagnetic valve communicating with the remote unit channel, the electromagnetic valve being capable of making the remote diverting opening communicate with any one of the two remote unit outlets;
- a power supply unit electrically connected to the electromagnetic valve;
- an operating device signalingly connected to the electromagnetic valve;
- two manual pressure adjusting valves mounted on the manual control unit, and one of the two manual pressure adjusting valves communicating with one of the two manual unit outlets;
- and
- two remote pressure adjusting valves mounted on the remote control unit, and the two remote pressure adjusting valves communicating with the two remote unit outlets respectively.
