摘要： A high-pressure pump for supplying fuel to an internal-combustion engine has a pump body and an actuating shaft which extends along a longitudinal axis and which is supported rotatably about the longitudinal axis by the pump body. The shaft has an eccentric portion and a prismatic jacking end. A first pumping station has a gear engaged with the prismatic jacking end and a second pumping station has at least one piston. The piston is slidable relative to the pump body transversely with respect to the longitudinal axis and is actuated by the eccentric portion of the actuating shaft. The prismatic jacking end is made of a harder material than the material with which the remainder of the actuating shaft is made.

摘要： Although modern diesel fuel formulations are intended to reduce emissions of diesel engines, at least some of those modern fuels tend to have relatively low lubricity levels. The control valve assemblies described herein help to minimize any increased wear that would otherwise result from the use of such low lubricity fuels by providing a valve element, a valve guide, and an insert. The valve element is received within the valve guide and is moveable between an open position and a closed position. The insert forms a first sealed interface and a second sealed interface with the valve element and the valve guide. When the valve element is in the closed position, both of the first sealed interface and the second sealed interface are engaged. When the valve element is in the open position, only one of the first sealed interface and the second sealed interface is engaged.

摘要： A planocentric drive mechanism is disclosed which includes a plurality of longitudinally extending pins arranged in a circle about an axis of rotation, a rotating shaft which carries an eccentric cam, and a pinion gear which is rotatably carried by the eccentric cam. The pinion gear has a plurality of apertures formed therethrough, within which the pins are disposed, thereby limiting the pinion gear to oscillation. An output shaft is aligned with and rotatably about the axis of rotation, and includes a plurality of second pins which mesh with cycloidal teeth disposed about the periphery of the pinion gear.

摘要： A pivot pipe for a two-cylinder thick material sludge pump is designed to reduce the rate of wear of the sealing surfaces and flow bores of the pivot pipe and cooperating outlets on the two pump cylinders. As the pivot pipe oscillates from one pump cylinder to the other pump cylinder the contacting sealing surfaces are subjected to abrasion and impact wear. The present invention limits the rate of wear between the contacting sealing surfaces and a portion of the flow bore by fixing monolithic wearing rings on the upstream end of the pivot pipe and on the outlets of the two pump cylinders. The monolithic wearing rings are made of a hard materials such as cemented tungsten carbide.

摘要： A transfer pump used in a waste tank for transferring high-level radioactive liquid waste from a waste tank and having a column assembly, a canned electric motor means, and an impeller assembly with an upper impeller and a lower impeller connected to a shaft of a rotor assembly. The column assembly locates a motor housing with the electric motor means adjacent to the impeller assembly which creates an hydraulic head, and which forces the liquid waste, into the motor housing to cool the electric motor means and to cool and/or lubricate the radial and thrust bearing assemblies. Hard-on-hard bearing surfaces of the bearing assemblies and a ring assembly between the upper impeller and electric motor means grind large particles in the liquid waste flow. Slots in the static bearing member of the radial bearing assemblies further grind down the solid waste particles so that only particles smaller than the clearances in the system can pass therethrough, thereby resisting damage to and the interruption of the operation of the transfer pump. The column assembly is modular so that sections can be easily assembled, disassembled and/or removed. A second embodiment employs a stator jacket which provides an alternate means for cooling the electric motor means and lubricating and/or cooling the bearing assemblies, and a third embodiment employs a variable level suction device which allows liquid waste to be drawn into the transfer pump from varying and discrete levels in the waste tank.
