Abstract: A fluid conditioning module having a fluid inlet and a fluid outlet is provided. The fluid conditioning module includes a first pump element, a second pump element, a pressure regulator, a controller, and a prime mover to impart rotational motion in the first and second pump elements. A first pump inlet is in fluid communication with the fluid inlet. A filter inlet is in fluid communication with a first pump outlet and a second pump outlet, and a filter outlet is in fluid communication with the fluid outlet. A pressure regulator inlet and a pressure regulator outlet are in fluid communication with the filter outlet and a recirculation conduit, respectively. The control valve has a first position and a second position, which allows fluid flow through the recirculation conduit. The controller adjusts operation of one or more of the prime mover and the control valve based upon a predetermined parameter.

Abstract: A pressure relief valve for a common rail fuel system includes a hard ceramic spherical valve member that moves into and out of contact with a conical valve seat of a soft metallic valve body. Fretting damage to the valve is inhibited by using the dissimilar materials, and by using a guide pin that is allowed to move on the spherical surface of the ceramic spherical valve member. The valve member may be constructed of silicon nitride.

Abstract: A multipart fuel filter element includes a cartridge body having a plurality of through bores radially offset with respect to a centerline. An inlet end cap adjacent a first cartridge face includes an inlet aperture centrally aligned with the centerline and a plurality of distribution apertures aligned with and directing fuel to the plurality of through bores. An outlet end cap adjacent a second cartridge face includes an outlet aperture also aligned with the centerline and a plurality of reception aperture that are aligned with the through bores to receive fuel.
