Abstract: A valve lifter assembly for deactivating a cylinder in an internal combustion engine. The valve lifter assembly is provided with a plunger movably disposed within a bore of a main body member to controllably isolate the cam lift from the rocker arm and valve of the engine. The plunger is normally locked in an extended position to transmit cam lift to reciprocatingly operate the valve. At least one locking pin is moveably disposed within the plunger to engage an inner annular groove of the main body member. Pressurized oil is provided to dislodge the locking pins from the annular groove and allow the plunger to move within the main body member, thereby isolating the cam lift from the rocker arm and valve. The deactivating lifter is preferably disposed within the recess conventionally provided for hydraulic valve lifters.

Abstract: An oil distribution system for an internal combustion engine comprising a longitudinal bore in the engine head or block connected to an engine oil pump. A longitudinal insert is disposed in the engine bore, the insert being formed and disposed to define segmented galleries within the bore, a first oil gallery being in communication with the engine camshaft bearings and a second oil gallery being in communication with switchable cam followers in the engine. The two galleries are separated but connected by one or more oil control valves. Thus, the camshaft bearings are exposed to high engine oil pressure at all times independent of the switchable cam followers; likewise, the switchable cam followers may be latched and unlatched at any time or condition deemed beneficial for engine operation without jeopardizing lubrication sufficiency to the camshaft bearings.

Abstract: A hydraulic valve lifter including venting means to assure venting of air through the lifter and filling thereof with oil during pre-start filling of the engine oil galleries after engine assembly. Patterning of a hemispherical pushrod seat surface, and/or patterning of either or both of the mating surfaces of a pushrod seat and a piston, permits air purged from the engine through a pushrod to be vented through the lifter. Such means may be temporary or permanent and may include coatings of the surfaces with materials that are destroyed by engine action after starting. Permanent means may include surface grooves in the mating surfaces and/or small-diameter passages between the hemispherical seat surface and the cylindrical outer surface of the pushrod seat. Venting means in accordance with the invention is useful for both valve-deactivating and non-valve-deactivating valve lifters.

Abstract: Oil metering valve means in a hydraulic valve lifter configured such that a metering plate cooperates with a pushrod seat to meter the flow of oil in a forward direction. The metering means is also conducive to the flow of oil in the reverse direction, permitting an oil reservoir in the lifter to be filled by reverse oil flow, either after assembly of the lifter or upon engine shutdown. Embodiments of such oil metering valve means may include: a metering plate having one or more notches around its periphery to permit oil to flow past the plate and a feature supporting the plate; a metering plate having one or more apertures to permit oil to flow through the plate; a metering plate having one or more nonplanar areas along the edges of the plate to prevent sealing of the plate against the supportive feature; and a metering-plate supportive feature having one or more irregularities, such as grooves, bumps, or undulations to permit flow around the edge of the plate past the irregularities.

Abstract: A deactivation valve lifter includes a lifter body. The lifter body has a first end configured for engaging a cam of an engine and at least one annular pin chamber. A pin housing includes a pin housing bottom. The pin housing bottom defines at least one pin stop aperture and a radially directed pin bore. A deactivation pin assembly is disposed within the pin bore and includes pin members. The pin housing is concentrically disposed within the lifter body. A portion of each pin member may be disposed within the annular pin chamber to thereby selectively couple and decouple the lifter body to the pin housing. A drain aperture defined by the pin housing bottom extends from the pin bore to an outside surface of the pin housing. A stop pin is disposed in the at least one pin stop aperture for limiting the inward motion of the pin members.

Abstract: An anti-rotation guide for a deactivation hydraulic valve lifter for an internal combustion engine. The guide includes a through bore accommodating of a hydraulic valve lifter and is sized such that the outer end of the lifter may be inserted into the through bore of the guide. The guide is securable to the engine such that the lifter is reciprocable within the guide. The guide is provided with two opposing keepers for mating with corresponding flats on the lifter to prevent rotation of the lifter. Further, a keyway means is provided in the guide and lifter to prevent the lifter being inserted into the guide 180° from the correct orientation.

Abstract: A low mass two-step valve lifter has concentric inner and outer cylindrical cam followers engagable by radially disposed axially aligned lock pins in the outer high lift follower. Both inner and outer followers have cylindrically crowned cam engaging surfaces for high lift capability and low load eccentricity. The lock pins are positioned on the lifter thrust axis normal to the direction of the engine camshaft axis and the skirt has upward seal extensions and downward extending skirt portions adjacent the lock pin openings to maintain seal area. Other skirt portions are cut away to reduce weight. Vent holes in the lock pins discharge collected oil that might interfere with fast pin engagement. A separate passage is provided to feed oil to a hydraulic lash adjuster disposed in the inner follower cylinder. A single guide pin aligns the dual followers with the external bore oil ports and the camshaft cams. Additional features are also disclosed.
