Abstract: A system of alternate hose line bundling allows for exclusion of a higher pressure hose line from fasteners directly attached to a vehicle body. Alternatively to mounting to the vehicle body, the higher pressure hose line is coupled to a lower pressure hose line via fasteners which lack mounting features. Eliminating attachment of higher pressure hose lines to the vehicle body reduces noise, vibration, and harshness (NVH) experienced by passengers in the vehicle.

Abstract: A fuel delivery module for an automotive fuel delivery system includes a reservoir and a fuel pump. The fuel pump delivers fuel from the tank to the reservoir via a fuel tank inlet and reservoir outlet and from the reservoir to the engine via a reservoir inlet and engine outlet. The reservoir is formed with a plurality of contaminant traps for collecting contaminants contained in the fuel as the fuel is pumped through the reservoir such that the contaminants settle unto said contaminant traps thereby reducing the amount of contaminants entering the reservoir inlet.

Abstract: An electric-operated fuel pump assembly (20) has a vaned impeller (36) that is disposed within a pump housing (28) for rotation about an axis (22). A channel (44; 72) extend arcuately about the axis. A vapor vent hole (46; 46A) intersects the channel. Certain geometric relationships improve venting efficiency, and hence pump efficiency.

Abstract: A fuel pump has a motor mounted within a housing with a shaft extending therefrom to which a helically shaped impeller is fitted having at least two turns for pumping fuel from a fuel tank to an automotive engine. The impeller has an involute shaped leading edge designed to efficiently scoop fuel from an inlet into a pumping chamber formed between the helically shaped blade turns comprising the impeller. A trailing edge on the impeller has a narrowed width which increases the effective flow cross-sectional area, thus increasing the fuel pressure. The helically shaped impeller needs no separate casing, as is typically required for conventional fuel pumps employing regenerative turbines, gerotors, roller vanes, or the like, and increases fuel pressure over a longer circumferential distance thus decreasing cavitation.
Abstract translation: 燃料泵具有安装在壳体内的电动机，其中从其延伸的轴安装螺旋形叶轮至少两圈以将燃料从燃料箱泵送到汽车发动机。 叶轮具有渐开线形前缘，其被设计成有效地将燃料从入口铲入到形成在包括叶轮的螺旋形叶片之间的泵送室中。 叶轮上的后缘具有变宽的宽度，这增加了有效流动横截面积，从而增加了燃料压力。 螺旋形叶轮不需要单独的壳体，如通常使用再生涡轮机，齿轮转子，滚轮叶片等的常规燃料泵所需要的，并且在更长的周向距离上增加燃料压力，从而减小空化。

Abstract: A fuel pressure regulator is provided. The fuel pressure regulator includes a body forming an inlet and an outlet, a seal element positioned intermediate the inlet and the outlet, an armature positioned to apply force to the seal element, and a solenoid coiled around the armature, wherein excitation of the solenoid causes a change in at least one of a position of the armature relative to the seal element and a force applied by the armature to the seal element to vary a regulated fuel pressure set-point at which fuel flows through the outlet.

Abstract: A fuel pump is used for supplying fuel from a fuel tank to an automotive engine. The fuel pump includes a pump housing having an inlet end for receiving fuel from the fuel tank. A brushless DC motor is positioned within the pump housing and includes a rotatable rotor having magnets therein and a central aperture formed through the rotor. A plastic helical-shaped impeller is positioned within the central aperture for rotation with the rotor about a central axis for pumping fuel through the housing to the engine. The impeller has a plurality of vane blades with blade tips secured to the rotor to prevent tip losses. Each vane blade has a leading edge configured to generate laminar fluid flow and reduce vapor generation at the inlet end of the impeller.
