    摘要： An internal combustion engine may be provided with independently controllable valves, fuel injectors and ignition elements that may be used to start the engine without a separate auxiliary device such as an electric starter motor. The engine may fire the cylinders under a startup mode of control at the same time it fires the cylinders under a normal mode of control in order to smooth the transition from start up to normal operating mode. Additionally, an internal combustion engine may use independently controllable valves to stop the engine and ensure that one or more of the pistons come to rest at a position which allows them to be used to restart the engine.

    摘要： A unique gerotor-type pump is disclosed for pumping gases. The pump has an inner gear-type rotor mounted within and rotating off-center with respect to an outer gear-type rotor ring, about a parallel axis. Surfaces of the teeth of the inner rotor are in continuous contact with the outer rotor to define at least one pumping chamber which alternately expands and contracts as the inner and outer rotors turn. An elongated inlet port is positioned to communicate with the pumping chamber during a substantial portion of the cycle when the pumping chamber is expanding, (the intake cycle) and an outlet port is positioned to communicate with the pumping chamber only just prior to and at the end of the contraction or exhaust cycle. Oil for sealing and lubricating between moving parts of the pump is provided by employing differential pressure created by the pump's own operation to draw oil through passageways which communicate between an oil reservoir and the pumping chamber.

    摘要： A vehicle suspension system includes a vehicle body subframe, a wheel with a tire mounted upon a wheel hub assembly having a wheel spindle inside the wheel bearing. A wheel damping mass of ogival shape surrounds the outer race of the wheel bearing and is formed with a vertical slot whose length is perpendicular to the major diameter of the ogival cross section. The damping mass is formed with a pair of openings on each side of the vertical slot that accommodates a support assembly including a vertical shaft held by a shaft retainer intermediate the shaft ends, upper and lower bearings and centering springs located between the shaft retainer and each of the latter bearings. Damping fluid dissipates vibrational energy and may comprise a major component of the damping mass.

    摘要： A back-flow prevention valve assembly is disclosed for use with a vacuum pump or the like and employs a valve element movable between positions opening or closing a passageway through the assembly. In the event of pump failure, a control valve, which is operated by fluid from the pressure side of the pump, vents ambient air behind the valve element to assist it in moving rapidly to the closed position to prevent backflow. After resumption of pumping, a controlled withdrawal of ambient air behind the valve element delays opening of the valve until the pump has created a sufficient vacuum to minimize influx of air upstream when the valve opens.
