Patent number: 7946262Abstract: A lifter oil manifold assembly for variable actuation of engine valves having first (top) and second (valve) plates having portions of oil control and oil exhaust passages formed therein. The assembly further includes a carrier member having an oil supply passage integrated thereby separating the oil supply path from the oil control and oil exhaust path. Further, the assembly includes towers for receiving and positioning the electro-magnetic oil control valves used to control oil flow in the assembly. The towers are molded separate from the carrier and are held in place by the valve plate or are molded integral with the carrier. In another aspect of the invention, oil control valve retention springs are molded integral with either the tower or the oil control valve. In a further aspect of the invention, a combined polymer restrictor/strainer in the oil circuit replaces a prior art metal die-cast restrictor.Type: GrantFiled: February 1, 2008Date of Patent: May 24, 2011Assignee: Delphi Technologies, Inc.Inventors: Dominic Borraccia, Alan G. Strandburg, David M. Peers, Michael J. Dinkel, Michael E. McCarroll

Patent number: 7409941Abstract: A deactivating hydraulic valve mechanism includes a hydraulic element assembly disposed within cup within a pin housing slidably disposed within a bore in a body. A transverse bore in the pin housing contains selectively-retractable locking pins that engage a locking feature in the body to selectively lock together the body and the pin housing. A lost motion spring is disposed in a vented annular chamber between the body and the pin housing. An oil passage from an engine gallery to the hydraulic element assembly includes an axial component formed in the cup and bypasses the lost motion chamber. A ring holds the lifter assembly together and also sets mechanical lash. The ring may combine a standard-thickness ring and a shim selected to provided a predetermined amount of mechanical lash in the assembled mechanism to ensure facile engagement and disengagement of the locking pins in the body.Type: GrantFiled: April 11, 2006Date of Patent: August 12, 2008Assignee: Delphi Technologies, Inc.Inventors: Mark J.
