CAMSHAFT THRUST CONTROL SECURED BY DRIVE GEAR

The invention relates to camshaft thrust control secured by a drive gear. According to the invention, an apparatus and method of producing a pump including a housing and a cam received within the housing that is rotatable relative to the housing. The cam includes an axis of rotation. The pump further includes a retainer plate operable to abut the cam to restrict movement of the cam in a first direction along the axis of rotation. The pump further includes a biaser, such as a spring, operable to place a first constant force in the first direction on the retainer plate. 种生产泵的设备和方法，该泵包括外壳以及被容纳在所述外壳内的凸轮，所述凸轮能相对于所述外壳旋转。所述凸轮包括旋转轴线。所述泵还包括保持器板，所述保持器板能操作成抵接所述凸轮，以限制所述凸轮沿着所述旋转轴线在第方向上的移动。所述泵还包括诸如弹簧的偏置器，所述偏置器能操作成对所述保持器板施加在所述第方向上的恒定的第力。
