Abstract: A fuel injection pump is provided. The fuel injection pump includes a barrel including an inner surface defining a bore. The fuel injection pump also includes a plunger movable inside the bore of the barrel. An outer surface of the plunger and the inner surface of the barrel form a clearance therebetween. One or more sleeves at least partially encircle one or more portions of an outer surface of the barrel, and are configured to apply a load to the outer surface of the barrel.

Abstract: A high volume high pressure common rail pump for a fuel system includes pairs of pump head assemblies in phase with each other but oriented in opposition to one another about a rotating cam shaft. Pump pistons in the pump head assemblies simultaneously undergo pumping strokes via a shared two lobe cam of the rotating cam shaft. The pump may include two pairs of pump head assemblies, and each head assembly may include two pump pistons. The cam shaft includes two cams sufficiently out of phase with one another that the cam shaft always has a positive torque even when the cam lobes are symmetrical. In addition, because the pumping is done simultaneously on opposite sides of the cam shaft, the forces on the cam shaft are balanced and its support bearings experience less wear and tear.
Abstract translation: 用于燃料系统的高容量高压共轨泵包括相互相位但相对于旋转的凸轮轴彼此相对定向的成对的泵头组件。 泵头组件中的泵活塞同时通过旋转凸轮轴的共享的两个凸角凸轮进行泵送冲程。 泵可以包括两对泵头组件，并且每个头组件可以包括两个泵活塞。 凸轮轴包括彼此完全不相位的两个凸轮，即使当凸轮凸角对称时，凸轮轴总是具有正转矩。 另外，由于在凸轮轴的相对侧同时进行泵送，所以凸轮轴上的力是平衡的，并且其支撑轴承经历较少的磨损。
