It is composed of oil tank, power mechanism, reversing valve, pressure relief valve and pump oil mechanism. The oil pumping mechanism consists of oil pump body, high and low pressure oil outlet holes, eccentric shaft, eccentric bearing, driven gear and a pair of high pressure oil pumps and a The low-pressure oil pump is composed of an oil pump body suspended on the fuel tank cap, and high and low pressure oil outlet holes are provided on the oil pump body and connected with the pressure relief valve oil passage. The eccentric shaft is longitudinally arranged, the upper end is pivoted in the center of the oil pump body, and the lower end is solid Eccentric bearings are provided. The driven gear is fixed on the top of the eccentric shaft and is connected with the power mechanism. High and low pressure oil pumps are suspended on the oil pump body. Each has an actuating member that contacts the eccentric bearing. The pump chambers of the high and low pressure oil pumps Respectively with high and low pressure oil outlet hole. Advantages: The connection between the oil pumping mechanism and the power mechanism is vertical, which can make full use of space and miniaturize the floor space, which is conducive to operation and transportation; the pump oil form of high and low pressure oil pump is changed into the actuation form of eccentric bearing. With a simple structure, fewer parts and facilitate assembly.
