Abstract
The utility model discloses an improved engine oil pump assembly. The upper part of a pump body (6) is provided with two oil passages (5), the outer ends of the two oil passages are respectively communicated with an oil inlet or an oil outlet (7) on the pump body (6), the inner ends of the two oil passages are respectively communicated with two oil tanks (3) on a pump cover (4). The utility model effectively solves the problems of oil leakage and gas leakage, and the sealing performance of the assembly is obviously enhanced. Meanwhile, partial material is saved and manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of improved engine oil pump assembly, particularly a kind of modified model engine oil pump assembly that is used for diesel engine.Mainly be applicable to 195 diesel engines etc.
Background technique
Existing engine oil pump assembly, such as 195 assemblies, oil groove is opened on the pump cover, and does the Sealing of the pump cover and the pump housing with paper washer.Ubiquity leakage of oil, gas leakage are easy to cause the problem of engine oil pump assembly oil pressure and underfed.On the other hand, be opened on the pump cover because oil groove is whole, make the pump cover design comparatively complicated, the material of use is also many, so manufacture cost is higher.
The model utility content
Technical problem to be solved in the utility model provides a kind of follow-on engine oil pump assembly that adopts dark oil duct and novel seal mode, makes its sealability better, and manufacture cost is lower, is used to overcome the deficiency of above-mentioned existing procucts.
In order to address the above problem, the utility model has adopted following technological scheme.
A kind of improved engine oil pump assembly comprises the pump housing, pump cover and rotor assembly, and its specialization is: offer two oil ducts on the top of the described pump housing, their outer end is communicated with filler opening, oil outlet on the pump housing respectively; Their the inner is communicated with two oil grooves on the pump cover respectively.
At the pump housing and pump cover junction O-ring seal is installed.
The pump cover bottom is equipped with the paper sealing gasket with pump housing junction.
Dark oil duct is set on the pump housing and uses rubber seal that the pump cover and the pump housing are implemented sealing, efficiently solve the problem of leakage of oil, gas leakage, the assembly sealability is able to obvious raising.Pump cover has been save the part material simultaneously, has reduced manufacture cost.On the other hand, the pump cover bottom installs the paper sealing gasket additional, has solved the swap oil problem between the oil inlet and outlet.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is the inner side surface schematic representation of pump cover among the utility model embodiment
Embodiment
Further specify the utility model below in conjunction with embodiment.
As shown in Figure 1, embodiment of the present utility model comprises the pump housing 6, seal ring 1, pump cover 4 and rotor assembly.Wherein rotor assembly is made up of external rotor 8, internal rotor 9, rotor shaft 10 and rotor pin 2, and internal rotor 9 and rotor shaft 10 are fixed together by rotor pin 2, and external rotor 8 is enclosed within on the internal rotor 9.
Offer two oil ducts 5 on the top of the described pump housing 6, their outer end is communicated with filler opening or oil outlet 7 on the pump housing 6 respectively; Their the inner is communicated with two oil grooves 3 on the pump cover 4 respectively.At the pump housing 6 and pump cover 4 junctions O-ring seal 1 is installed, i.e. the ring-shaped rubber seal ring.In order to solve the swap oil problem between the oil inlet and outlet, the paper sealing gasket is installed in pump cover 4 bottoms and the pump housing 6 junctions.
The pump housing 6 and pump cover 4 mutual drive fits, and fixedly connected by two hexagon socket head cap screws.
The oil pressure of this engine oil pump assembly is identical with existing product with flow.
Claims (3)
1, a kind of improved engine oil pump assembly, comprise the pump housing (6), pump cover (4) and rotor assembly, it is characterized in that: offer two oil ducts (5) on the top of the described pump housing (6), their outer end is communicated with filler opening or oil outlet (7) on the pump housing (6) respectively; Their the inner is communicated with two oil grooves (3) on the pump cover (4) respectively.
2, improved engine oil pump assembly as claimed in claim 1 is characterized in that: at the pump housing (6) and pump cover (4) junction O-ring seal (1) is installed.
