  • Publication number: 20160348636
    Abstract: A high efficiency optical ignition device is provided in a two-part compact and robust package to be mounted directly on an internal combustion engine chamber. The ignition device ignites a combustion fuel with a high intensity plasma generated by a high power laser beam from a solid state laser operable in Q-switched, or non-Q-switched mode for producing short or long pulses, respectively. Multiple pulses are generated, and duration and frequency of the laser beam pulses are controlled by controlling an optical pump module to pump the solid state laser. The optical pump module comprises a semiconductor laser, preferably a VCSEL device. One or more laser beams are precisely directed, each one to a desired location anywhere within the combustion chamber for more efficient and near complete burning of the combustion fuel. The robust packaging is well suited to withstand mechanical and thermal stresses of the internal combustion engine.

  • Publication number: 20160348658
    Abstract: Systems and methods for detecting and arresting free fall of a mover in a linear motor for an ESP. In one embodiment, the motor of the ESP is initially automatically commutated, but is limited by the back pressure of the fluid being pumped. The drive system of the ESP monitors the speed of the mover in the linear motor and determines whether the speed of the mover exceeds a threshold speed (e.g., by determining whether time differentials between transitions in position sensor signals fall below a threshold value). If the speed of the mover does not exceed the threshold speed, the motor is deemed not to be in free fall. If the speed of the mover exceeds the threshold speed, the motor is considered to be in free fall, so automatic commutation of the motor is disabled and the mover is advanced through its stroke at a predetermined speed.

  • Publication number: 20160348672
    Abstract: An axial piston device may be operated as a pump and includes a self-centering rotary valve. The device includes a stationary housing encompassing a shaft and the rotary valve. The rotary valve and the shaft are coupled to each other. Upon rotation, the rotary valve self-centers as a result of elimination of moments and forces within the pump. The inventive pump is a piston device. The valve is within a valve bore, which is a part of a manifold. A shaft is within the manifold and the shaft is attached at its distal end to a planar surface of the rotary valve. The shaft has a first axis of rotation and the rotary valve has a second axis of rotation. During operation of the pump, the first axis is often times offset from the second axis. The pump operates via a swashplate with reciprocating pistons while the housing remains stationary.

    Abstract: An oil pump device includes an oil pump (10) and an electrically operated control valve (20). The valve adjusts hydraulic pressures to be applied to a decrease-side control pressure chamber (15A) for causing a pump casing (14) to swing in the discharge amount decrease direction and an increase-side control pressure chamber (15B) for causing the pump casing to swing in the discharge amount increase direction so as to hold the pump casing at a predetermined approximately intermediate position between the maximum swing position in the discharge amount decrease direction and the maximum swing position in the discharge amount increase direction by balancing the urging forces of a decrease-side return spring (16) for urging the pump casing in the discharge amount decrease direction and an increase-side return spring (17) for urging the pump casing in the discharge amount increase direction when supply of current to the valve is stopped.

  • Publication number: 20160348679
    Abstract: A vacuum pump system includes a secondary pumping mechanism incorporated into a stationary portion of a scroll pump. The stationary portion includes the stationary plate scroll of the scroll pump and defines a gas passageway in which the secondary pumping mechanism is disposed. The gas passageway is connected to a gas flow path through the scroll pump at a location upstream of an exhaust check valve of the scroll pump. The secondary pumping mechanism is displaceable within the gas passageway to draw residual gas in the compression stage upstream of the check valve into the gas passageway, and may pump the residual gas back out through the exhaust check valve, to evacuate residual gas from the compression stage.
