Appl. No.:

10/814251

US Classification:

Abstract:

A power conversion module comprises a stack-piezo disposed in a housing between a mechanical stop and a moveable piston adjacent a sealed chamber containing a fluid. The mechanical stop biases the stack-piezo expansion direction. An energized stack-piezo expands and moves the piston, which in turn applies compressive force to the fluid in the sealed chamber. The forces applied to the fluid displaces a shaft slidably mounted in a channel formed in the chamber. A biasing means returns the shaft to its starting position when the piezo is de-energized. The sealed chamber preferably has a large diameter adjacent the piston, and a smaller diameter opening for the channel, through which the shaft moves. Preferably, the sealed chamber mostly has a frustoconical shape. The shaft deflection distance may be varied by altering the ratio of the fluid-exposed surface area of the piston to that of the shaft and altering the stack-piezo's length.

Abstract:

A fuel oil burner for a heating system includes a nozzle having an inlet and outlet, and an electric solenoid valve having an inlet for receiving pressurized fuel oil from a fuel supply system and an outlet in communication with the inlet of the nozzle. The valve is configured to prevent flow of fuel oil through the valve to the nozzle in a closed state and to permit flow of fuel oil through the valve to the nozzle in an open state. A controller in communication with the valve is configured to intermittently switch the valve between the closed state and the open state at predetermined time periods so that pulses of fuel oil exit the outlet of the nozzle. The valve is intermittently in the closed state a time period so that the pulses of fuel oil exiting the outlet of the nozzle self-sustain a flame.
