摘要： Cooling fins 72, 74 and 76 extend about the fuel pump 24, perpendicular to the longitudinal axis of the fuel pump and parallel to the anticipated direction of flow of the air stream generated by the movement of the vehicle. The cooling fins are formed on the pump bowl 36, hood 34, and mounting arm 49 to extract the heat of conduction transferred from the engine block 12 to the mounting arm 49 and heat of radiation and convection transferred from the engine block and its accessories to the pump bowl 36, hood 34 and mounting arm 49.

摘要： A segmented seal plate supporting a brush seal mounted in the space between the compressor and turbine and bearing against the shaft of a microturbine engine form a barrier in this cavity and serves to control flow in this space. A plurality of circumferentially spaced discretely sized holes in the seal plate judiciously located above the brush seal bearing against the shaft interconnecting the back-to-back mounted compressor/turbine controls the amount of cooling air so that the combination of the brush seal, segmented plate and discretely sized holes controls the leakage from the compressor of each engine of a given model and controls cooling flow to the turbine for reducing efficiency scatter from engine to engine.

摘要： An ultrasonic pump in which a medium is pumped by the interaction between longitudinal acoustic waves and the medium in a flow-chamber. The pump comprises a transducer and an associated chamber for providing a controllable, focused, acoustic traveling wave therein. The chamber includes a tapered passage corresponding to the focused beam pattern of the focused acoustic traveling wave through which the liquid medium flows and/or cavitation is induced and/or controlled. The pump therefore utilizes an acoustical transducer responsive to frequency input for directing longitudinal acoustic waves into the flow-chamber which induces a pressure gradient. The medium in the flow-chamber flows in the direction of travel of the acoustic wave in the chamber as a result of acoustic streaming. The exit orifice of the nozzle in communication with the chamber is strategically located at about the focal zone of the focused, traveling wave. Thus, the pump provides ultrasonic control of a medium to provide selective motion and cavitation.

摘要： An apparatus for protecting a fluid pump motor includes an electric motor for driving a pump head to pressurize a fluid. A liner is positioned in the motor air gap to prevent pressurized fluid from contacting one or more magnetic field producing elements of the stator. The liner includes a thin wall to minimize the air gap distance. The liner wall is made thin enough that, under loading of the pressurized fluid, the liner wall deforms and bears against one or more of the field producing elements of the stator for structural support. The liner is preferably fabricated as a single metal part using a deep drawing process that results in a can having opposed open and closed ends with a substantially uniform cross-section between the open and closed ends of the can.

摘要： An improved turbocharger for railway locomotive sized engines includes, in a preferred embodiment, first and second axially spaced ball bearings supporting a rotor with the first bearing being a hybrid ceramic ball bearing mounted to accept both radial and axial loads acting on the shaft at the compressor end. The first bearing is mounted on a reduced diameter portion of the shaft, providing reduced bearing diameter to acceptably limit centrifugal loading of ceramic balls in the bearing against a surrounding bearing race. The first bearing has dual rows of ceramic ball bearings mounted to share all axial thrust loads on the shaft. The second bearing is also a ball bearing. Lubrication of the bearings is preferably by direct impingement on the inner race to minimize oil churning causing heating and power loss. Additional features and advantages are disclosed.

摘要： A cooling fan system has a fan assembly that is removably housed in a chassis. The fan assembly receives electrical power, and the fan blades rotate when housed inside the chassis. As the fan assembly is removed from an opening in the chassis, the power to the fan assembly is disconnected, but the fan blades may continue to rotate. A mechanical stopper, such as a row of bristles that extends into the opening in the chassis, interferes with the rotation of the fan blades as the fan assembly is removed from the chassis. The mechanical stopper stops rotation of the fan blades, thereby preventing harm to the user removing the fan assembly. After the fan assembly is completely removed from the chassis, a spring-loaded door closes the opening in the chassis further protecting the user from contacting adjacent spinning fan blades or hazardous energy sources within the chassis.

摘要： A portable power unit having an internal combustion engine, a tank for holding a supply of pressurized fluid, an electrical generator powered by the internal combustion engine, and a pump selectively powered by the internal combustion engine. An electro-magnetic clutch is energized by a pressure switch on the tank when the pressure in the tank falls below a predetermined value, and a cooling fan for the pump may also be energized by the pressure switch together with the clutch. A non-slip positive drive belt couples power from the engine to the generator. The generator is overdriven at a shaft rotation speed above that of the engine's shaft, and the pump is underdriven at a shaft rotation speed below that of the engine's shaft.
