Abstract: A nozzle assembly for converting liquid from a liquid source into a spray flow using air from an air pressure source to atomize the liquid. The nozzle assembly comprises a housing having an air inlet for connection to the air pressure source, a liquid inlet for connection to the liquid source, and an outlet. A series of first air passages are formed in the housing for receiving air from the air inlet. The first air passages communicate with the outlet and are configured to generate a swirled air stream. A second air passage in the housing is also provided and is configured to generate a linear air stream. There is a liquid passage for receiving liquid from the liquid inlet. The liquid passage contracts to a reduced cross-sectional area adjacent the housing outlet. The first and second air passages and the liquid passage terminate in a common atomization zone adjacent the housing outlet where liquid flowing through the liquid passage is atomized into a spray pattern.

Abstract: A ventilation system for ventilating fresh air to a conditioned space, the system capable of supplying substantially more air to the space than is removed by the system in order to prevent depressurization inside the space. Passing through the unit housing is an inflow chamber, an outflow chamber, and a make-up air duct. Two blowers, an intake blower and an exhaust blower, are placed within the inflow chamber and the outflow chamber in order to motivate inflow and outflow currents of air. A damper acts to open and close the make-up air duct. When the damper is in an open position and the intake blower operates at a higher speed than the exhaust blower the system increases the air pressure within the conditioned space. A heat transfer wheel is disposed within both the inflow chamber and the outflow chamber to exchange heat between the two currents of air. A pre-heater is placed in the make-up air duct to be used in cold weather conditions to heat the air which bypasses the heat recovery wheel.

In one embodiment, the inverter voltage is adjusted to minimize utility supplied reactive and real power and to actively dampen EMI filter voltage, with the inverter voltage command being developed though a multi-loop PPI control system.

Abstract: An unbalance compensated bypass valve (14, 21, 23) for a gas turbine engine fuel supply system is responsive to the fuel pressure differential across a fuel metering valve (15) to open and close a bypass orifice (37, 39, 41; 89, 91, 93; 99, 101, 103). The bypass valve (14, 21, 23) selectively supplies high fuel pressure to a compensating cavity (45, 95, 120) providing a counterbalancing force against an annular area (47, 97, 124) of the bypass valve piston (34, 81, 83, 111, 112) to compensate for increased restorative forces of a helical reference spring (57, 112, 125) as that spring is collapsed as well as to compensate for other unbalance conditions within the valve (14, 21, 23). The compensating cavity may include a variable orifice inlet (37, 39, 41), (99, 101, 103), or (89, 91, 93) and a variable orifice outlet (105, 107, 109) or the inlet orifice may be variable while the outlet orifice (43, 96, 99) is fixed.

The inlet region forms an intake port. The outlet region forms a supply port and an exhaust port. The blower unit is maintained within the housing, such that operation of the blower generates an airflow within the housing from the inlet region to the outlet region. Finally, the chute is mounted within the outlet region adjacent the exhaust port and is configured to direct a portion of the airflow to the exhaust port. With this configuration, an overall size of the blower module housing is greatly reduced.
