Description

可变输送叶片油泵
技术领域
本发明涉及一种可变输送叶片油泵。
特别地，本发明涉及一种如下类型的可变输送叶片油泵，该油泵包括：转子，该转子安装成围绕其纵向轴线旋转，并且具有多个径向向外敞开的沟槽；定子，该定子围绕转子延伸，并且相对于转子本身偏心地安装；多个叶片，每个叶片滑动地安装在相应的沟槽内部，并具有布置成与定子基本接触的外缘；和调节装置，该调节装置用于选择性地控制转子和定子之间的偏心率，从而控制泵的输送。
背景技术
上述类型的已知可变输送叶片油泵具有一些缺点，这些缺点主要源于叶片和定子之间具有较高的滑动摩擦的事实。
发明内容
本发明的目的是提供一种可变输送叶片油泵，该可变输送叶片油泵没有上述缺点。
根据本发明，提供一种如所附权利要求所要求保护的可变输送叶片油泵。
附图的简单说明
现在将参考示出本发明的非限制性实施例的实例的附图描述本发明，其中：
图1是本发明的叶片泵的优选实施例的示意性纵向剖面图；
图2是沿着图1中的线II-II截取的剖面图；和
图3是沿着图1中的线III-III截取的剖面图。
实施本发明的最佳模式
参考图1至3，作为整体以1表示的是可变输送叶片泵，该可变输送叶片泵用于将油馈送到车辆(未示出)的内燃机(未示出)的润滑回路(未示出)。
泵1包括具有基本平行六面体矩形剖面的支承壳体2，并且又包括由基本平坦表面4横向地限制的第一板3。板3设有空腔5，该空腔5具有垂直于表面4的纵向轴线6，并且在表面4上向外敞开，并且由布置成与表面4本身接触的第二板7轴向地封闭。
泵1还包括动力轴8，该动力轴通过板3和7安装成围绕轴线6旋转，并且承载有带键的圆柱形转子9，该圆柱形转子9容纳在空腔5的内部，并且平行于轴线6测量的宽度基本等于也平行于轴线6测量的空腔5的宽度。
空腔5在内部还容纳有定子10，该定子10围绕转子9延伸，并且平行于轴线6测量的宽度基本等于也平行于轴线6测量的空腔5的宽度，并且在内部由相对于转子9布置在偏心位置中的基本圆柱形表面11限制。
定子10铰接到板3，以相对于板3本身并且在已知类型的调节装置12的控制下围绕平行于轴线6的支点轴线13摆动，因此允许选择性地控制转子9和表面11之间的偏心率。
转子9具有两个圆柱形的相互相对的空腔14，这些空腔14与轴线6同轴地获得，并且一个面对板3而另一个面对板7，并且转子9设有多个径向沟槽15(在所示的情况下，六个沟槽15)，所述沟槽15平行于轴线6地通过转子9获得，且围绕轴线6均匀地分布，在转子9的外表面16处与轴线6同轴地径向向外敞开，并且还在空腔14处轴向向外敞开。
每个沟槽15被具有外缘18的叶片17滑动地接合，该外缘18平行于轴线6延伸，并且通过在外缘18与定子10的表面11之间布置环形靴19布置成基本与定子10的表面11接触。
平行于轴线6测量的靴19的宽度基本上等于也平行于轴线6测量的叶片17的宽度，并且靴19周向地联接到定子10和叶片17。
每个叶片从在空腔14内部的相应沟槽15轴向地突出，并且具有内缘20，所述内缘20平行于轴线6延伸，并且布置成基本与两个环形元件21接触，每个环形元件21容纳在空腔14中的一个中，并且围绕轴8延伸，并且具有的直径大于轴8的直径并小于相应空腔14的直径，以便在相应空腔14本身的内部浮动。
每对相应相邻的叶片17周向地限定相应的泵送室22，该泵送室22还由转子9和靴19径向地限定且由板3和7轴向地限定，该泵送室22由转子9围绕轴线6并通过油的吸入口23和输出口24移动，并且随着转子9围绕轴线6的旋转、随着转子9与定子10的表面11之间的偏心率，该泵送室具有可变的容积。
此外，关于上述情况需重点指出的是，通过定子10围绕轴线13的移动，以及因此改变转子9与定子10的表面11本身之间的偏心率，选择性地控制每个腔室22在吸入口23和输出口24处的容积，并且因此选择性地控制泵1的输送。
如图2所示，每个叶片17包括多个箔25(在所示的情况下四个箔25)，这些箔25相互重叠，并且彼此滑动地径向联接，以确保叶片17与靴19之间较有效的流体密封联接。
根据未示出的变体，靴19被容纳在相应的空腔内，所述空腔在定子10中获得，并且在表面11上向外敞开，并且靴19从相应的空腔向外突出，以将本身布置成与相应的叶片17接触。
从以上描述容易地推断出泵1的操作，并且无需任何进一步说明。
