Title: Oil filter restriction sensor

Abstract

This patent describes an oil filter sensor device for insertion between the oil filter mounting bracket mounted on an internal combustion engine and an oil filter cartridge having a filter element therein. The sensor device provides a warning to an operator of the engine if a restricted oil filter condition occurs, the sensor device includes: a. a disk-shaped body means having a first generally flat surface and an opposite second generally flat surface; b. the body means having a first longitudinal passageway centrally positioned through the body means to carry filtered oil between the oil filter element and the engine bracket interconnecting through the first and second surfaces. A second longitudinal passageway is separately formed in the body means to carry incoming unfiltered oil between the engine bracket and the oil filter cartridge and arranged to interconnect through the first and second surfaces; c. a closed internal cylindrical bore formed in the body means having a first end opening through the outer surface of the body means, a slidable piston mounted within the cylindrical bore and sized to closely fit the diameter of the bore, a removable plug suitably mounted within the open end of the bore to close andmore » seal the bore and to restrict the movement of the piston; and d. a biasing means positioned within the bore between the plug and the piston to bias the piston in a first position away from the plug. The plug has an insulated electrical connector mounted therein which extends into the bore so that the piston when it moves to a second position against the biasing means makes electrical contact with the connector.« less
