    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: A valve deactivation lifter including means for restricting relative rotation between the pin housing and the lifter body. When used in a V-style or slant engine, a prior art deactivation lifter can be subject to oil drainage during engine shutdown if the oil supply port in the pin housing rests in the “down” position. In an improved lifter, relative rotation between the pin housing and the lifter body is limited and the pin housing is oriented such that the oil supply port is never on the underside of the pin housing. Rotation may be limited by any of several means, for example, a ball disposed in a dimple in the pin housing and extending into a longitudinal groove in the lifter body, and a flat on the pin housing and locking means installed in the lifter body to engage the flat and thus prevent rotation of the pin housing.

    摘要: A deactivation valve lifter includes a lifter body. The body defines at least one annular pin chamber therein. The lifter body has a first end configured for engaging a cam of an engine. A pin housing includes a pin housing wall and pin housing bottom. The pin housing wall includes an outer surface. The pin housing bottom defines a radially directed pin bore. The pin housing is concentrically disposed within the lifter body such that the outer surface of the pin housing wall is adjacent to at least a portion of an inner wall of the lifter body. A deactivation pin assembly is disposed within the pin bore and includes pin members. A portion of each pin member is disposed within the annular pin chamber to thereby couple the lifter body to the pin housing. An external lost motion spring is coupled to the body and pin housing.

    摘要: A deactivation hydraulic valve lifter includes an elongate lifter body having a substantially cylindrical inner wall. The inner wall defines at least one annular pin chamber therein. The lifter body has a first end configured for engaging a cam of an engine. An elongate pin housing includes a substantially cylindrical pin housing wall and pin housing bottom. The pin housing wall includes an inner surface and an outer surface. The pin housing bottom defines a radially directed pin bore therethrough. The pin housing is concentrically disposed within the inner wall of the lifter body such that the outer surface of the pin housing wall is adjacent to at least a portion of the inner wall of the lifter body. A deactivation pin assembly is disposed within the pin bore and includes two pin members. The pin members are biased radially outward relative to each other. A portion of each pin member is disposed within the annular pin chamber to thereby couple the lifter body to the pin housing. The pin members are configured for moving toward each other when the pin chamber is pressurized, thereby retracting the pin members from within the annular pin chamber and decoupling the lifter body from the pin housing.

    摘要: A valve-deactivation hydraulic valve lifter including a conventional hydraulic lash adjuster means disposed within a pin housing slidably disposed in a lifter body. A transverse bore in the pin housing contains opposed locking pins for selectively engaging a circumferential groove including a locking surface in the lifter body whereby the lifter body and the pin housing may be engaged or disengaged to activate or deactivate a pushrod controlling an engine valve. Ends of the locking pins are spherical so that the pins cannot become stuck in corners in the groove. The groove corner is rounded be either a positive radius or a negative radius to remove a sharp corner known to be an originating and propagating point for stress failure of the lifter body in prior art lifters. The edge of each pin and the edge of the locking surface are chamfered to prevent damage to these edges during locking and unlocking. A second surface intermediate an outer surface of the pin housing and the transverse bore is also provided. A retaining ring holding the lifter assembly together may be augmented by a spacer whose thickness is selected to yield a predetermined amount of mechanical lash in the deactivation lifter.
