Abstract: A fuel pump is provided having improved efficiency by lowering the wet circle index of the pump while maintaining robust axial clearances to meet the demands of an automotive application. One embodiment includes a fuel pump for pressurizing fuel for delivery to an engine of a motor vehicle. The fuel pump generally comprises a housing, a motor, a single sided impeller, a cover and a body. The provision of a single sided impeller greatly reduces the wet circle index and improves the pump efficiency. The cover, impeller, and body are structured to axially balance the impeller which is free floating on the shaft of the motor.

Abstract: A constant velocity (CV) joint and, more particularly, a retaining ring for a CV joint and a method of assembling a retaining ring on a CV joint. The tripod constant velocity joint may be assembled by placing a retaining ring in alignment with a trunnion head, applying a force to the aligned retaining ring to expand the diameter of said retaining ring so that a fracture area on the retaining ring fractures. After the fracture area fractures, the retaining ring is displaced into a retaining groove on the trunnion. The retaining ring includes an outer surface, an inner surface, a first notch extending from one of the inner and outer surfaces to the other of the inner and outer surfaces, and a fracture area extending from the first notch to the other of the inner and outer surfaces.

Abstract: A planetary differential including a differential case rotatable about an axis and a method of manufacturing thereof. The differential case includes a cover, a housing, an annulus gear, and a ring gear. The differential case defines a differential cavity having a clutch cavity and a planet cavity separated by a retainer plate coupled to the housing. The modular nature of this system allows both open and torque biasing constructions in the same packaging space. The method of manufacturing the differential includes the steps of coupling a retainer plate to the housing between the clutch cavity and the axial opening, placing a planetary gear set in the planetary cavity, and fixing the housing to the annulus gear and ring gear.

Abstract: A vehicle fuel rail system for fuel delivery and liquid fuel retainment therein. The vehicle fuel rail system comprises a fuel rail and a chassis connector in fluid communication with the fuel rail. The fuel rail has a first bank and a second bank connected to the first bank by way of a crossover line. The first bank has a first top portion and a first bottom portion and the second bank has a second top portion and a second bottom portion. The crossover line has a first end disposed at the first bottom portion and a second end disposed at the second top portion. The chassis connector has a tank end and an rail end wherein the tank end is connected to the vehicle fuel tank and the rail end is disposed at the first top portion.
