Description

汽油发动机的机油泵总成外形结构
技术领域
本实用新型涉及一种汽油发动机，特别涉及一种汽油发动机的机油泵总成外形结构。
背景技术
汽油发动机的机油泵总成需安装在发动机油底壳件和裙架件内，其安装空间较小。以往设计的机油泵总成外形比较高和宽，就迫使发动机油底壳铸件外形和内腔放大来满足高宽机油泵的安装，这样就引起发动机油底壳体积增大，费材料及增加自重，从而影响耗汽油。
实用新型内容
本实用新型所要解决的技术问题是提供一种汽油发动机的机油泵总成外形结构，其减小了体积，满足紧凑空间安装的需要和减轻了重量。
为解决所述技术问题，本实用新型提供了一种汽油发动机的机油泵总成外形结构，其特征在于，其包括油道内腔、限压阀、定位孔、渐开线齿轮内腔、泵盖外形件，限压阀固定在油道内腔和渐开线齿轮内腔之间，泵盖外形件和定位孔分别固定在渐开线齿轮内腔的两侧，定位孔的高度小于油道内腔的高度。
本实用新型的积极进步效果在于：本实用新型减小了体积，满足紧凑空间安装的需要和减轻了重量。
附图说明
图1为本实用新型一实施例的结构示意图。
具体实施方式
下面举个较佳实施例，并结合附图来更清楚完整地说明本实用新型。
如图1所示，本实用新型包括油道内腔1、限压阀2、定位孔3、渐开线齿轮内腔4、泵盖外形件5，限压阀2固定在油道内腔1和渐开线齿轮内腔4之间，泵盖外形件5和定位孔3分别固定在渐开线齿轮内腔4的两侧，定位孔3的高度小于油道内腔1的高度，定位孔3的高度为三十毫米，油道内腔1的高度为五十毫米，这样的结构减小了体积，满足紧凑空间安装的需要和减轻了重量。
虽然以上描述了本实用新型的具体实施方式，但是本领域的技术人员应当理解，这些仅是举例说明，在不背离本实用新型的原理和实质的前提下，可以对这些实施方式做出多种变更或修改。因此，本实用新型的保护范围由所附权利要求书限定。
