Abstract: Disclosed is an oil pump comprising a housing (1), a mounting passage (114), a piston (116) and an elastic member (115). The mounting passage (114) may be formed in the housing (1) defining a first end communicated with a high pressure oil chamber (112) and a sealed second end. The mounting passage (114) may be formed with at least one oil release port (119) and at least one pressure relief port (117) adjacent to the second end for communicating with a low pressure oil chamber (113). The piston (116) may be slidable along the mounting passage (114), and the elastic member (115) may elastically press against the pistion to close the first end. Further, an engine comprising the oil pump and a vehicle comprising the engine are also provided.
