    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: 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.

    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 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.
