具体实施方式
请参阅图1-12所示，一种叶片泵，包括泵壳7，以及设置在泵壳7开口处的端盖1；所述端盖1和泵壳7之间转动连接有转轴8，所述转轴8位于端盖1和泵壳7的偏心位置，所述转轴8的一端伸出泵壳7；所述泵壳7内固定安装有定子3，所述定子3与泵壳7同轴设置；所述定子3内设有叶片腔301；所述叶片腔301内转动连接有转子4，所述转子4与定子3同轴设置；所述转子4的圆周侧面沿其径向设有插接槽401，所述插接槽401内滑动连接有叶片5；所述转子4内的中心位置设有齿轮腔403；所述齿轮腔403的内圆周侧壁上设有凸齿402，所述转轴8固定安装有与凸齿402啮合的内齿轮6，所述内齿轮6位于转子4的偏心位置处；所述端盖1内以及泵壳7内在定子3的端部均设有配流盘2，所述配流盘2上均设有与齿轮腔403的吸油区连通的第一配流孔2a、与齿轮腔403的排油区连通的第二配流孔2b、与叶片腔301的吸油区连通的两个对称设置的第三配流孔2c、与叶片腔301排油区连通的两个对称设置的第四配流孔2e；这里所述第一配流孔2a和第二配流孔2b均为腰型孔。所述端盖1内设有与第一配流孔2a连通的第一配流槽1a、与第一配流槽1a连通的进油口101、与第四配流孔2e连通的第二配流槽1c、与第二配流槽1c连通的出油口102、以及用于连通第二配流孔2b和第三配流孔2c的第三配流槽1b。所述端盖1上插接有溢流阀9，所述端盖1内设有用于连通第三配流槽1b和溢流阀9的进口的第一通孔1h、以及用于连通进油口101和溢流阀9的出口的第二通孔1g。
所述端盖1朝向泵壳7的端面上设有安装槽103，配流盘2位于安装槽103内。所述安装槽103的内圆周侧壁上以及泵壳7的内圆周侧壁上均对称设有卡槽104，所述配流盘2的圆周侧面对称设有卡接到所述卡槽104内的凸块201。所述泵壳7内在与转轴8连接处设有轴承66，所述轴承66的内圈与转轴8之间以及轴承66的外圈和泵壳7之间均为过盈配合。
当叶片泵需要工作时，需要将电机和叶片泵的转轴8相连，打开电机带动转轴8旋转，由于转轴8与内齿轮6平键相连，又因为内齿轮6与转子4内部凸齿402的啮合关系，使得内齿轮6转动时带动转子4一起转动，此时在转子4内部形成一个内啮合的齿轮泵装置，转子4外部插入叶片5并与定子3的叶片腔301之间形成叶片泵结构，当叶片泵开始工作时，液压油从进油口101被吸入，经过第一配流槽1a、第一配流孔2a、进入齿轮腔403的吸油区通过内啮合的齿轮泵装置进行预增压，在经过第二配流孔2b、第三配流槽1b，第三配流孔2c进入叶片腔301的吸油区。由于内啮合的齿轮泵装置提供的油液总是大于叶片泵所需要的油液，多余油液经过第三配流槽1b、第一通孔1h、溢流阀9的进口、溢流阀9的出口、第二通孔1g流回到进油口101处,而进入叶片腔301吸油区的油液通过转子4旋转，使液压油经过第四配流孔2e和第二配流槽1c进入到出油口102，并排除泵外，本发明通过转子4内部内啮合的齿轮泵装置将液压油进行预升压，排入到叶片腔301吸油区中，使叶片5在旋转，吸油腔增大的过程中更容易的吸油，而且通过溢流阀9的调节，可以更加准确地控制传送至叶片腔301吸油区内油液的压力，解决了叶片泵本身自吸能力不足的问题，从而避免了叶片泵的气穴现象，延长了叶片泵的使用寿命，本发明通过集成的方式将齿轮泵装置设置在叶片泵内，节省空间，结构紧凑。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
