Patent number: 10378673Abstract: An active drain liquid trap configured for use with a fuel tank system and constructed in accordance to one example of the present disclosure includes a trap body, a float and a pilot. The trap body defines a first inlet, a second inlet and an outlet. The first inlet is fluidly connected to a fuel pump. The second inlet is fluidly connected to a vapor line. The float is rotatably mounted about a float pivot. The pilot moves between an open and closed position. Rotation of the float causes the pilot to be urged into an open position and fluid to be drained from the trap body through the outlet.Type: GrantFiled: March 22, 2017Date of Patent: August 13, 2019Assignee: Eaton CorporationInventors: Steven Lee Ambrose, Vaughn K. Mills

Publication number: 20170036531Abstract: A fuel tank system constructed in accordance to one example of the present disclosure includes a fuel tank, a purge canister, a valve assembly and a bypass means. The valve assembly can be fluidly coupled between the fuel tank and the purge canister and that selectively controls fuel vapor flow between the fuel tank and the purge canister. The bypass means can selectively bypass fuel vapor around at least a portion of the valve assembly from the fuel tank to the purge canister. The bypass means can include a bypass valve.Type: ApplicationFiled: October 25, 2016Publication date: February 9, 2017Applicant: Eaton CorporationInventors: Raymond Bruce McLauchlan, Steven Lee Ambrose, Jeffrey Bernard Smith, Mustafa Huseyin

Patent number: 8823390Abstract: A method for monitoring operation of a solenoid valve having an armature and a poppet coupled to the armature includes the steps of energizing a coil in the valve to generate a current signature reflecting current vs. time, detecting a first inflection point in the current signature, wherein the first inflection point occurs when the armature starts to move from one of the open and closed positions toward the other of the open and closed positions, and detecting a second inflection point in the current signature. The second inflection point occurs when the armature moves completely to the other of the open and closed positions. In one embodiment, the first inflection point indicates when the valve begins to open, making it possible to accurately determine the elapsed opening time of the valve.Type: GrantFiled: June 15, 2011Date of Patent: September 2, 2014Assignee: Eaton CorporationInventors: Robert Dean Keller, Steven Lee Ambrose, Eric Otis Barrows

Patent number: 8523089Abstract: A pressure swirl atomizer includes a nozzle having an exit orifice and a plurality of tangential swirl channels and a pintle that is movable within a pintle bearing between a closed position that closes the exit orifice and an open position that opens the exit orifice. The atomizer also has a pole piece having a channel, and the pole piece and the pintle are separated by an air gap when the pintle is in the closed position. A space between the pintle and the pintle bearing, the air gap, and the channel together form at least a part of a return path. Fluid from the tangential swirl channels drains through the return path when the pintle is in the closed position. To open the atomizer, a solenoid generates a magnetic force when energized, attracting the pintle toward the pole piece into the open position. A check valve disposed in the return path generates a fluid back pressure when the solenoid is de-energized to push the pintle toward the closed position.Type: GrantFiled: April 15, 2011Date of Patent: September 3, 2013Assignee: International Engine Intellectual Property Company, LLCInventors: Daniel William Bamber, Steven Lee Ambrose, Eric Otis Barrows

Publication number: 20110253809Abstract: A pressure swirl atomizer has a swirl chamber with an exit orifice and a plurality of tangential swirl channels disposed around the circumference of the swirl chamber. A pintle bearing surrounds a pintle. The pintle has a body portion and a nose portion that is narrower than the body portion. The nose portion has a tip that opens and closes the exit orifice and a side that is movable in the pintle bearing. In one embodiment, a return path formed between the nose portion of the pintle and the pintle bearing drains fluid from the swirl chamber when the exit orifice is closed. The nose portion positions the return path closer to a centerline of the atomizer, forcing fluid to swirl in the swirl chamber before draining. Since the fluid does not remain static in the chamber, less energy is needed to increase the fluid velocity and quickly form a desired spray pattern when the exit orifice is opened.Type: ApplicationFiled: April 15, 2011Publication date: October 20, 2011Inventors: Daniel William Bamber, Steven Lee Ambrose, Dale Arden Stretch

Publication number: 20110079085Abstract: An integrated fluid pressure sensor system includes a printed circuit board, a pressure manifold having a pressure source, and a sensor. The printed circuit board may be coupled to a pressure manifold. The printed circuit board and the pressure manifold may define a pressure cavity. The pressure source can be operatively configured to release fluid into the pressure cavity. The sensor may be affixed to the printed circuit board within the pressure cavity. The sealing member may be disposed between the printed circuit board and the pressure manifold. The gasket may be operatively configured to seal the pressure cavity.Type: ApplicationFiled: October 6, 2009Publication date: April 7, 2011Inventors: Robert John Kanda, Mark Louis Dell'Eva, Steven Lee Ambrose
