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: 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.

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.
