The invention discloses a vane oil pump. According to the invention, a vane fluid pump for a vehicle component is provided with an inner rotor supported within a cam. The inner rotor has an outer wall extending between first and second end faces, the outer wall defining a series of slots spaced apart about the outer wall to provide a series of outer wall sections. One of the wall sections defines a groove. Another of the wall sections is independent of grooves or is ungrooved. The pump has vanes positioned within respective slots of the inner rotor and extending outwardly to contact the continuous inner wall of the cam. The groove on the inner rotor is configured fluidly couple with a notch on the housing to provide fluid flow to the discharge port from an upstream pumping chamber to disrupt harmonics during operation to reduce pressure ripples and associated tonal noise. 本公开涉及种叶片油泵。种用于车辆部件的叶片流体泵设置有支撑在凸轮内的内转子。内转子具有在第端面和第二端面之间延伸的外壁，外壁限定围绕外壁间隔开的系列槽口以提供系列外壁段。壁段中的个限定槽。壁段中的另外的壁段与槽无关或不开槽。泵具有位于内转子的各个槽内并且向外延伸以与凸轮的连续的
