Abstract
An electronic modulating oven valve provides advantages over prior art designs. Additionally, for at least some embodiments, a dual passage valve operating in a modulating manner has been found to be desirable for oven and possibly other applications.
Claims19
A valve comprising:
- a gas inlet and a gas outlet;
- an actuator intermediate the gas inlet and the gas outlet for selectively directing gas from the gas inlet to the gas outlet;
- said actuator having first and second passages in communication with the gas inlet and gas outlet with first and second bores which are respectively transitioned from closed to an open configuration with movement of first and second pistons in the passages;
- and
- said pistons electrically coupled to a processor, said processor controlling movement of the pistons between the open and closed configurations whereby when in the open configurations the first and second passages communicate the gas inlet with the gas outlet, wherein fluid flowing through the first passage does not flow through the second passage.

A valve comprising:
- a gas inlet and a gas outlet;
- an actuator intermediate the gas inlet and the gas outlet for selectively directing gas from the gas inlet to the gas outlet;
- said actuator having a first passage with a first piston selectively transitioned from a closed to an open configuration;
- and
- a processor coupled to the actuator electrically controlling movement of the first piston between the open and closed configurations, and when the first piston is in the open configuration, gas flows from the gas inlet to the gas outlet through the first passage, and
- a second piston and a second passage by passing the first passage for flow from the gas inlet to the gas outlet, with the second piston selectively transitioned from a closed to an open configuration;
- and wherein the processor coupled to the actuator electrically controls movement of the second piston between the open and closed configurations.
