Latest Patents

One of Sutton's latest patents is an improvement in automotive fuel pump assemblies. This invention features a tubular cylindrical housing that contains an electric motor and a pump driven by the motor's armature. The design includes a first pump body adjacent to a flux ring of the motor, a second pump body positioned between the first pump body and the end of the housing, and an impeller located in a cavity between the pump bodies. The innovation lies in the incorporation of axially extending grooves on the outer cylindrical surfaces of the pump bodies, which align in a specific angular relationship. Spring clips fit into these grooves to maintain the positional relationship and facilitate efficient handling before insertion into the housing.

Another significant patent by Sutton is an apparatus for detecting water in fuel. This invention addresses the issue of insulating coatings that diesel fuel can deposit on surfaces. The detection system employs a probe, preferably designed as a siphon tube, connected to a circuit that responds to low resistance or high capacitance between the probe and ground. Initially uncoated, the probe establishes a resistive connection to a fuel container when water accumulates. As insulating deposits coat the probe, capacitive coupling occurs, triggering an output signal from the detection circuit when water is present.
