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.

摘要： An improved SHVL for an internal combustion engine comprises an improved arrangement for locking a spring tower into a pin housing. The spring tower is provided with an annular OD groove as in the prior art. The pin housing ID groove is modified to have a two-step groove comprising two adjacent regions having different depths (different diameters) and having a distinct transition lip therebetween. A spring clip of the correct size seats properly in the spring tower groove and in the lesser-diameter pin housing groove, resulting in a correct overall length of the SHVL. Any oversize clip is caught between the lower lip of the spring tower groove and the transition lip of the two-step pin housing groove, resulting in a SHVL distinctly shorter than nominal, which is easily detected by either direct length measurement or a gauge.

摘要： An improved pin housing sub-assembly configured for reliable assembly and stability as an intermediate sub-assembly. The length of the plunger return spring is greater than the diameter of the spring well in the pin housing, such that the spring cannot be accidentally installed sideways in the well. During assembly, the non-compressed longer spring places the pushrod seat flush with the end of the pin housing. A shallow annular groove is provided in the inner wall of the pin housing near the outer end thereof, and an expansion ring may be installed therein when the plunger return spring is slightly compressed. The expansion ring holds the sub-assembly together as an intermediate but is displaced by the spring tower in a subsequent assembly step to become the locking ring between the pin housing and the spring tower, as in the prior art.

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 plunger having a substantially cylindrical plunger wall with an inner surface and an outer surface is concentrically disposed within the pin housing such that the outer surface of the plunger wall is adjacent to at least a portion of the inner surface of the pin housing wall. 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： 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.
