TODAY’S PATENT – AIR EXPANSION COMPENSATOR

Today’s invention was invented by Robert A. Burlew, William R. Tabor and Harry Zaverzence on 3^rd June, 2003, bearing patent No. US6572395B1. The invention was assigned to Electrical Wiring Component Applications Partnership.

Generally vehicles have oil pressure sensors or oxygen pressure sensors with sealed electrical connectors, which experience rapid air expansion due to increase in temperature. These changes cause moisture to travel through the wires which effect the calibration of the sensor. Hence, a device is need to compensate for the changes in air pressure.

The present invention provides a flexible air expansion compensator including an air chamber. The air expansion compensator mates with a terminal cavity of a sealed electrical connector to compensate for the heating and cooling of air trapped in a device that contains the sealed electrical connector. Compensator includes a hollow body portion or air chamber  and a connector portion for mating with a terminal cavity of a sealed electrical connector.
