Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil pump bodies, in particular to a leakage-proof oil pump body. Background Art
[0002] The oil pump raises the oil to a certain pressure and forcibly delivers it to the moving surfaces of various engine components. When the engine is running, the drive gear on the camshaft drives the oil pump's transmission gear, rotating the driving gear fixed to the driving gear shaft. This in turn drives the driven gear in the opposite direction, moving the oil from the oil inlet chamber through the tooth gaps and the pump wall to the oil outlet chamber. This creates a low pressure in the oil inlet chamber, generating suction, which draws the oil from the oil pan into the oil chamber. As the driving and driven gears rotate continuously, the oil is continuously pumped to the required locations. The oil pump's compact structure creates a sealed chamber without the need for additional isolation components. Seals are installed around the joints of the pump body to prevent leakage.
[0003] However, the position of the inlet and outlet pipes on the oil pump body is such that the connecting pipe is directly inserted and fixed with the inlet and outlet pipes on the pump body through the connecting head, so that the oil on the pump body can enter and exit through the connecting pipe. The connecting pipe relies on the squeezing of the connecting head and the outer wall of the inlet and outlet pipe to achieve the sealing of the oil. During actual use, due to the influence of the oil pressure, the connection between the connecting head on the oil connecting pipe and the inlet and outlet pipes of the pump body is easy to loosen, resulting in insufficient sealing between the moving connecting head and the inlet and outlet pipes, causing oil leakage.
