Abstract:
A control valve module for gaseous fuels on spark ignited reciprocating engines is presented. The control valve module has a valve that controls gaseous fuel flow to a mixer or other device for air/fuel ratio control, an actuator for moving the valve position, and a controller. The controller receives a signal from a heated exhaust gas oxygen (HEGO) sensor that is an indication of the fuel/air ratio and actuates the valve to control the combustion mixture to a precise stoichiometric ratio.

Abstract:
A fluid metering valve includes a gear rack which is slidable on a valve stem in which a spring counteracts the force of an actuator to maintain a constant load on the gear mechanism to prevent backlash. Corresponding stop mechanisms between the gear and the shaft of a rotary actuator come into engagement with each other near a fully closed position of the fluid metering valve for zero calibration purposes upon power loss to the actuator. A single valve member and a single actuator of the fluid metering valve provides for both a shut-off function and a metering function.
Thermal management solutions for higher power LEDs. In accordance with embodiments, a heat sink, preferably copper, is connected directly to the thermal pad of an LED. Directly connecting the LED thermal pad to the copper heat sink reduces the thermal resistance between the LED package and the heat sink, and more efficiently conducts heat away from the LED through the copper heat sink. In embodiments, the copper heat sink is directly soldered to the LED thermal pad.
