威格士4535V-42A38/45A38/50A38/60A38-1AA-22R葉片泵，雙作用葉片泵結構特點(1)定子過渡曲線定子內表面的曲線由四段圓弧和四段過渡曲線組成(見圖)理想的過渡曲線不僅應使葉片在槽中滑動時的徑向速度和加速度，變化均勻，而且應使葉片轉到過渡曲線和圓弧交接點處的加速度突變不大，以減小沖擊和噪聲。目前雙作用葉片泵--般都使用綜合性能較好的等加速、等減速曲線或高次曲線作為過渡曲線。
葉片安放角如圖所示，葉片在壓油區工作時，它們均受定子內表面推力的作用不斷縮回槽內。當葉片在轉子中徑向安放時，定子表面對葉片作用力的方向與葉片沿槽滑動的方向所成的壓力角β較大，因而葉片在槽內運動時所受到的摩擦力也較大，使葉片滑動困難，甚至被卡住或折斷。為了解決.這一矛盾，可以將葉片不按徑向安放，而是順轉向前傾一個角度日，這時的壓力角就是β°=β-θ。壓力角的減小有利于葉片在槽內的滑動，所以雙作用葉片泵轉子的葉片槽常做成向前傾斜-一個安放角日。在葉片前傾安放時，葉片泵的轉子就不允許反轉。
