摘要： A pump assembly flows pressurized engine oil to HEUI fuel injectors in a diesel engine. The assembly includes an inlet throttle valve which controls the volume of oil flowed to the pump dependent upon the difference between the pump outlet pressure and a desired outlet pressure determined by an electronic control module for the diesel engine.

摘要： A component for a downhole tool includes a rotor and a hardfacing precursor. The hardfacing precursor includes a polymeric material, hard particles, and a metal. A hydraulic drilling motor includes a stator, a rotor, and a sintered hardfacing material on an outer surface of the rotor or an inner surface of the stator. Methods of applying hardfacing to surfaces include forming a paste of hard particles, metal matrix particles, a polymeric material, and a solvent. The solvent is removed from the paste to form a sheet, which is applied to a surface and heated. A component for a downhole tool includes a first hardfacing material, a second hardfacing material over the first hardfacing material and defining a plurality of pores, and a metal disposed within at least some of the pores. The metal has a melting point lower than a melting point of the second hardfacing material.

For at least one of the end faces, the land(s) include(s) the first material and the contact surface is defined by a surface layer of the second material on the first material. A method of axially positioning a rotor of a rotary engine within an internal cavity of an outer body of the engine are also discussed.

摘要： A plunger pump includes a cylinder section having a cylinder chamber and a spacer section sliding against a portion of the plunger closer to a proximal end side than a portion of a plunger advancing and retracting into the cylinder chamber. The cylinder section is made of a material having first hardness, and the spacer section being made of a resin material having second hardness softer than the first hardness. A length in an axial direction from a proximal end of a sliding portion of the spacer section sliding against the plunger to a distal end of the spacer section is larger than a maximum stroke length of reciprocation of the plunger.
