Improve as one, described oil pump body is positioned at described oil pump and goes out the safety valve that oil pocket place is also provided with connection oil sump.
Improve as one, described oil pump body is the aluminium press oil pump body of jewelling manufacture technics.
After have employed technique scheme, the beneficial effects of the utility model are: because oil pump comprises oil pump body, described oil pump body is provided with oil pump filler opening and oil pump oil outlet, described oil pump body interior is provided with external rotor and internal rotor, between described external rotor and internal rotor, forming machine oil pump oil suction chamber and oil pump go out oil pocket, main oil gallery pressure-limit valve and special oil duct is provided with in described oil pump body, described main oil gallery pressure-limit valve is connected with main oil gallery by described special oil duct, thus lubricant oil is inner from oil pump filler opening ingress engine oil pump body, pressurizeed by external rotor and internal rotor, motor is entered into through oil pump oil outlet, the lubricating oil pressure of main oil gallery controls the unlatching of main oil gallery pressure-limit valve, when main oil gallery oil pressure is too high, main oil gallery pressure-limit valve valve opening, the lubricant oil that oil pump goes out oil pocket enters into oil pump oil suction chamber, is reduced the pressure of main oil gallery by the oil pump capacity of reduce engine oil pump.The oil pump that the utility model provides, adopts external rotor and internal rotor to pressurize to lubricant oil, under the prerequisite meeting engine lubricating oil demand, is integrated with main oil gallery pressure-limit valve, makes compact structure, decrease the step of assembling while decreasing parts design; Main oil gallery pressure-limit valve adopts internal drainage type simultaneously, improves the efficiency of oil pump.
The safety valve that oil pocket place is also provided with connection oil sump is gone out owing to described oil pump body being positioned at described oil pump; when the oil pressure that oil pump goes out oil pocket is too high; lubricant oil is directly leaked in oil sump by safety valve; play the effect of protection oil pump; thus be integrated with safety valve when integrated main oil gallery pressure-limit valve, make structure compacter.
Due to the aluminium press oil pump body that described oil pump body is jewelling manufacture technics, the weight of oil pump is declined to a great extent.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Shown in common as shown in Figure 1 to Figure 4, a kind of oil pump, comprises oil pump body 1, and oil pump body 1 is provided with oil pump filler opening 2 and oil pump oil outlet 3, and oil pump body 1 inside is provided with external rotor 4 and the internal rotor 5 suitable with external rotor 4; The inner chamber of external rotor 4 is divided into the active chamber of some by internal rotor 5, active chamber increases at oil pump filler opening 2 volume, suck lubricant oil, reduce at oil pump oil outlet 3 volume, extrude lubricant oil, namely between external rotor 4 and internal rotor 5, forming machine oil pump oil suction chamber 6 and oil pump go out oil pocket 7, and oil pump oil suction chamber 6 is arranged near oil pump filler opening 2, and oil pump goes out oil pocket 7 and arranges near oil pump oil outlet 3.
Above-mentioned internal rotor 5 is connected with internal rotor rotating shaft 51, and the end winding support of internal rotor rotating shaft 51 has sprocket wheel 52, and internal rotor rotating shaft 51 and sprocket wheel 52 are well known to those skilled in the art, and do not repeat them here.
The main oil gallery pressure-limit valve 8 for limiting main oil gallery (not shown) pressure is provided with in oil pump body 1, main oil gallery pressure-limit valve 8 is communicated with oil pump oil suction chamber 6 and oil pump goes out oil pocket 7, and main oil gallery pressure-limit valve 8 is connected with main oil gallery by the special oil duct 9 on oil pump body 1.
Above-mentioned main oil gallery is a special oil duct in engine body, is used for distributing through filtering and cooled lubricant oil to engine component; Main oil gallery pressure is an important indicator of reflection engine behavior, is well known to those skilled in the art, does not repeat them here.
