Publication number: 20220268223Abstract: An evaporative emissions control system configured for use with a vehicle fuel tank includes a purge canister, an accelerometer, first and second vent tubes that terminate at first and second vent openings, a first vent valve, a second vent valve, a vent shut-off assembly and a control module. The accelerometer senses acceleration in an x, y and z axis. The first vent valve is fluidly coupled to the first vent tube. The second vent valve is fluidly coupled to the second vent tube. The vent shutoff assembly selectively opens and closes the first and second valves. The control module estimates a location of liquid fuel based on the sensed acceleration from the accelerometer and determines which vent opening is one of submerged and about to be submerged based on the estimated location of the liquid fuel. The control module closes the vent valve associated with the determined vent opening.Type: ApplicationFiled: February 22, 2021Publication date: August 25, 2022Applicant: Eaton Intelligent Power LimitedInventors: Nikhil Nahar, Sudeep Motilal Solanki, Max Russell Franklin, Vaughn Kevin Mills, Mark Beaupre, Matthew Memmer, Robert Andrew Dayton

Patent number: 11268480Abstract: A vapor impermeable solenoid for a fuel tank isolation valve assembly an outer housing defining an inner cavity, windings configured to generate a magnetic flux when energized, and a flux collector configured to direct the magnetic flux. An armature tube is disposed within the inner cavity inboard of the flux collector and formed of a magnetic and vapor impermeable material configured to prevent fuel vapor molecules from passing therethrough. A pole piece is disposed within the armature tube, and a magnetic armature is disposed within the armature tube and operably coupled to a seal configured to selectively seal a passage that allows fuel vapor to pass to a purge canister. The magnetic armature is configured to move from a first position to a second position when an electric current is applied to the windings.Type: GrantFiled: December 3, 2020Date of Patent: March 8, 2022Assignee: Eaton Intelligent Power LimitedInventor: Robert Andrew Dayton

Publication number: 20170130897Abstract: An oil control valve assembly includes a valve body and a controller coupled to an exterior end of the valve body. The controller includes a solenoid housing attached to the exterior end of the valve body, and defines an interior region. An encapsulated coil assembly is disposed within the interior region of the solenoid housing. A housing seal is disposed within the interior region of the solenoid housing, in sealing engagement with the solenoid housing, the valve body, and the encapsulated coil assembly. The housing seal is operable to seal the interior region of the solenoid housing to prevent fluid communication between the solenoid housing and the valve body. An adapter assembly is coupled to the valve body to reposition a discharge location of a supply port, a control port, and an exhaust port of the valve body along a longitudinal axis of the valve body.Type: ApplicationFiled: January 19, 2017Publication date: May 11, 2017Applicant: Eaton CorporationInventors: Robert Andrew Dayton, Robert John Boychuk, Daniel William Bamber, Fred Andrew Weeks

Patent number: 7556062Abstract: A solenoid valve and method has a simplified structure that integrates the fluid metering functions of the spool in the armature, thereby eliminating the need for a separate spool, bearings, and pin in the valve. The armature has a aperture that communicates with at least one port in a valve body. The position of the differential in the armature with respect to the ports in the valve body controls the pressure of fluid exiting the outputs of the valve body. In one embodiment, the same overall valve structure can be modified to form both inversely proportional valves and directly proportional valves. By integrating the fluid metering functions of the spool into a single ported armature, the inventive valve assembly reduces the number of parts in the valve, simplifying construction.Type: GrantFiled: September 15, 2005Date of Patent: July 7, 2009Assignee: Eaton CorporationInventors: William John Arnold, Robert Andrew Dayton
