Patent number: 9784143Abstract: A valve timing control device, in effect a cam phaser, for an internal combustion engine. The valve timing control device includes a rotor connected to a camshaft and having a plurality of vanes. A stator is engaged with the rotor, and includes a plurality of webs. Pressure chambers are provided between each of the webs and vanes. The cam phaser is configured to automatically locate to its mid-lock position, without having to rely on electronic control. At least one embodiment of the present invention is configured to use cam torque to recirculate oil from one side of the vanes of the rotor to the other.Type: GrantFiled: June 18, 2015Date of Patent: October 10, 2017Assignee: HILITE GERMANY GMBHInventors: John Snyder, Steve Nance, Udo Diederichs, Melissa Koenig, Daniel Stanhope, Kenneth J.

Patent number: 9422840Abstract: In a hydraulic valve comprising a spool, one or more band-shape check valves and an enclosing bolt or snout, the check valve may be compressed to the point of excessive wear or failure and may impede spool movement. The problem outlined is solved by an inventive hydraulic valve for use with a cam phasing apparatus of an internal combustion engine. The hydraulic valve comprises a hollow bolt or snout, check valves, and a spool disposed inside the bolt while still being able to shift axially within the bolt. The bolt and spool are configured to provide fluid passageways between the spool and the cam phasing apparatus depending on a translational displacement of the spool. Furthermore, the spool is configured to allow an oil flow through the fluid passageway, yet limit a compression of the band-type check valves.Type: GrantFiled: June 24, 2014Date of Patent: August 23, 2016Assignee: HILITE GERMANY GMBHInventors: Kenneth J. Parker, John Snyder, Brian Sapp, Udo Diederichs, Melissa Mei Koenig

Patent number: 9341090Abstract: An oscillating-motor camshaft adjuster which provides that, through software, camshaft alternating torque is utilized only in conditions where the torque is adequate and/or it is important to reduce flow consumption. If there is two step lift and the camshaft alternating torque is not adequate in low lift, software can position the spool to utilize some camshaft alternating torque while also tanking oil to speed up the phasing.Type: GrantFiled: February 6, 2014Date of Patent: May 17, 2016Assignee: HILITE GERMANY GMBHInventors: Bernd Last, Gordon Neudörfer, Udo Diederichs, Matthew Bradfield, Melissa Mei Koenig, Kenneth J.

Publication number: 20090212246Abstract: A gasket fits between a deck plate and a solenoid valve in a lifter oil manifold assembly. The valve has a planar end surface with valve ports. The gasket has gasket ports for alignment with the valve ports. The gasket further has a planar sealing surface. The planar sealing surface on the gasket surrounds the gasket ports, and abuts the end surface of the solenoid valve fully around the valve ports. The gasket preferably includes a rib structure that extends lengthwise to surround the array of gasket ports. The rib structure is deflectable to the plane of the sealing surface under a clamping force applied to the gasket by the deck plate and the end surface of the valve.Type: ApplicationFiled: September 25, 2008Publication date: August 27, 2009Inventors: Brent J.

Publication number: 20070284008Abstract: A valve body has a bore in an exhaust flow path extending from a supply port to an exhaust port. The bore is bounded by a cylindrical inner surface with a stationary throttling corner. A cylindrical outer surface of a throttling member has a movable throttling corner. The movable throttling corner on the throttling member is sized to constrict the exhaust flow path upon moving coaxially toward the stationary throttling corner on the valve body. The movable throttling corner and the cylindrical outer surface are together sized to close the exhaust flow path upon moving coaxially past the stationary throttling corner and into the bore.Type: ApplicationFiled: October 24, 2006Publication date: December 13, 2007Inventors: Brent J.

Publication number: 20020162323Abstract: A solenoid operated valve suitable for controlling flow of air for injection into the exhaust of an engine, the poppet is connected to the solenoid armature in a lost-motion connection. Upon energization, the armature achieves momentum during the lost-motion movement and imports an impulse to the poppet to ensure movement in the event of any tendency of the poppet to stick. A one-way valve prevents exhaust back pressure from opening the poppet.Type: ApplicationFiled: May 2, 2001Publication date: November 7, 2002Applicant: EATON CORPORATIONInventors: Charles A.

Patent number: 6363920Abstract: An improved regulator valve 10 for controlling the purging of fuel vapors collected in a canister 12 and an evaporative emission control system into an intake system 18 of an internal combustion engine employs a solenoid valve assembly 40 with an armature 86 disposed outside of the coil 58 to operate with low friction. A spring 90 separating the armature 86 from the valve member 98 allows the spring 98 to absorb most of the magnetic and gravitational side loading.Type: GrantFiled: May 25, 2000Date of Patent: April 2, 2002Assignee: Eaton CorporationInventors: Kenneth J.

Patent number: 6364281Abstract: A solenoid operated valve is controlled upon increasing energization for greater flow by incrementing by a small fraction of the maximum current a target current level for the desired flow for a short duration followed by energization at the target level. Upon decreasing energization for lesser flow, the valve is energized at a target current decremented by a small fraction of the maximum current for a short duration. The result is a nearly negligible hysteresis.Type: GrantFiled: March 22, 2000Date of Patent: April 2, 2002Assignee: Eaton CorporationInventors: Daniel L. DeLand, Andrew W. Westergaard, Kenneth J. Parker, Roger L. Kennedy, Jr.
