ABSTRACT:
An air-gas mixing device of the type used to mix air and gaseous fuel as a gaseous fuel charge for an internal combustion engine and having air and gaseous fuel valves for controlling the air-fuel mixture. For more optimum control of the air-fuel mixture, a linear variable differential transformer is coupled to each valve to detect the exact position of the valve at any particular engine operating condition and the detection is transmitted to a remote measuring instrument and control station. If the engine is not operating at its most optimum efficiency, the fuel valve may then be moved to a predetermined position relative to the air valve to provide this efficiency. Internal electrical wires of the device are connected to an external wiring harness through an interconnector in a manner to prevent contamination of interconnecting electrical contacts in a corrosive atmosphere or an explosion caused by arcing of the contacts during connection or disconnection in an explosive atmosphere. The interconnector is retained on the air inlet housing of the device in a manner which allows the housing to move relative to the interconnector without interfering with the electrical connection.
