    Abstract: A hydraulic pulsation damper system for installation into an otherwise rigid hydraulic system to absorb and extinguish pressure pulsations being transmitted through the system by hydraulic fluid contained therein. The system is useful in suppressing pulsations in automotive fuel lines supplying fuel to fuel injection systems. The system includes fuel-conducting tubing made of flexible, non-permeable material that includes a convoluted central portion capable of expanding and contracting in response to pulsations in the fuel. Resilient foam is molded around the convoluted portion for controlling expansion of the convolutions. The foam and convoluted tubing are contained within a housing made from a larger-diameter hose having ends sealed as by swaged connectors. The damper system may be bent to accommodate installation with a fuel line in an engine and can conveniently provide a sound-deadening link in the fuel line of a vehicle between a body-mounted portion and an engine-mounted portion thereof.

    Abstract: A fuel vaporizer includes at least one surface and at least one glass coated thick film resistor applied to the at least one surface. The thick film resistor heats the surface and liquid fuel vaporizes on contact with the heated surface. By employing glass coated thick film, the fuel vaporizer provides a compact and economical solution for generating heat on a large heat transfer surface area. By integrating a temperature sensor into each heating area, the temperature of each heating area may be monitored and controlled individually. By providing multiple heated surface and multiple heater stages, rapid and complete fuel vaporization is provided. The generated fuel vapor may be used for any number of exhaust after-treatment processes, such as in exhaust fuel injection, diesel particulate filter burnout by igniting the vapor to perform fast warm-up of a nitrogen oxide absorber, or as an oxidation catalyst.

    Abstract: A fuel pump for supplying fuel at high fuel pressures includes a stationary body having a plurality of radial cylinders connecting with a central fuel chamber. Inlet and outlet passages communicate with the fuel chamber. Plungers are reciprocated in the cylinders by cam followers reciprocable in follower recesses of the body. A rotary internal cam engages the cam followers and is configured to reciprocate the plungers in timed relation to sequentially draw fuel from the inlet passage into the central fuel chamber and alternately force fuel from the central fuel chamber to the outlet passage in response to rotation of the rotary cam. A preferred embodiment includes paired smaller and larger diameter cylinders and pistons which are sequentially actuated in overlapping fashion to minimize pulsing of the pressurized fuel discharged from the pump into associated engine fuel lines.

    Abstract: A gerotor pump for pressurizing gasoline fuel is capable of developing pressures up to 2.0 MPa with good mechanical and volumetric efficiency and satisfying the durability requirements for an automotive fuel pump. The pump has been designed with optimized clearances and by including features that promote the formation of lubricating films of pressurized fuel. Features of the improved pump include the use of a shadow port in the side plate opposite the outlet port to promote balancing of high fuel pressures on the opposite sides of the rotors. Inner and outer rotors have predetermined side clearances with the clearances of the outer rotor being greater than those of the inner rotor in order to promote fuel pressure balance on the sides of the outer rotor. Support of the inner rotor and a drive shaft on a single bushing with bearing sleeves maintains concentricity. Additional features are disclosed.
