Abstract: A fuel pump is disclosed. The fuel pump includes a housing. Further, the fuel pump includes a rotatable pump shaft disposed within the housing. One end of the rotatable pump shaft is attachable to a gear. The housing also includes a retainer disposed within the housing and located about the pump shaft. The retainer includes a first rim and a second rim that are spaced apart from each other. The retainer also includes a side wall extending between the first and the second rims. Further, the side wall of the retainer defines a first volume and a second volume within the housing. The side wall of the retainer has a plurality of apertures configured to allow a fluid flow from the first volume to the second volume while retaining particulate contaminants larger than a size of the apertures within the first volume.
Abstract translation: 公开了一种燃油泵。 燃料泵包括壳体。 此外，燃料泵包括设置在壳体内的可旋转泵轴。 可旋转泵轴的一端可连接到齿轮上。 壳体还包括设置在壳体内并围绕泵轴定位的保持器。 保持器包括彼此间隔开的第一边缘和第二边缘。 保持器还包括在第一和第二边缘之间延伸的侧壁。 此外，保持器的侧壁限定了壳体内的第一容积和第二容积。 保持器的侧壁具有多个孔，其构造成允许流体从第一体积流到第二体积，同时保持大于第一体积内的孔的尺寸的颗粒污染物。

Abstract: The present disclosure provides a roller pin for a fuel pump. The roller pin includes a cylindrical body made of a first material extending between a first end and a second end. The roller pin includes an intermediate portion disposed between the first end and the second end of the cylindrical body. The intermediate portion is formed by depositing a second material on the cylindrical body. The roller pin further includes a longitudinal groove extending along the intermediate portion.
Abstract translation: 本公开提供了一种用于燃料泵的辊销。 辊销包括由在第一端和第二端之间延伸的第一材料制成的圆柱体。 辊销包括设置在圆柱体的第一端和第二端之间的中间部分。 中间部分通过将第二材料沉积在圆柱体上而形成。 辊销还包括沿着中间部分延伸的纵向凹槽。
