摘要： A fuel pump actuator comprising a body portion and a contact end fitted to the body portion for actuating a mechanical fuel pump in response to a camshaft lobe. A roller mounted to the body portion is configured to ride on the lobe. The contact end of the actuator engages a plunger of the fuel pump. The body portion of the actuator is preferably a body portion of a conventional hydraulic valve lifter and preferably includes a lash adjuster and is reciprocally disposed in a bore on the engine block. Lubrication of the reciprocating actuator is also similar to the lubrication provided to conventional valve lifters and lash adjusters. The contact end of the actuator is configured to reduce the mass of the actuator. Several styles of the contact end and ways of attaching the contact end to the body portion are provided.

摘要： An alignment feature for preventing in-bore rotation of an engine tappet. A first portion extends outwards from a tappet and a second portion extends into a hole in the tappet. The first portion extends longitudinally past the mounting hole such that when the feature and tappet are installed in an engine bore, the entire feature is prevented from rotation within the hole. The second portion extending orthogonally from the first portion into the mounting hole need not be close-fitting to the hole. The first portion may be substantially semi-cylindrical, having a convex cylindrical outer surface for fitting the walls of a semi-cylindrical channel in the engine bore and a concave cylindrical inner surface for fitting the outer wall of the tappet. The pin portion is preferably cylindrical. Other pin shapes are possible. The alignment feature may or may not be hardened.

摘要： A two-step roller finger follower having a high-lift follower portion that rotates relative to a low-lift follower portion about a pivot shaft, including a lost-motion compression spring disposed in a linear bore formed in the high-lift portion to exert force against an curved pad on the back side of the valve pallet of the low-lift portion. The spring is retained and guided in its bore by a spring retainer having a planar bottom for engaging the curved pad. Preferably the retainer is a cup positioned in the spring bore such that the stroke of the cup is limited, to prevent leak-down of the associated hydraulic lash adjuster. Driving the spring by a linear-acting retainer in a linear bore causes the spring to be compressed linearly, resulting in a highly stable and predictable spring rate.

摘要： A roller finger follower rocker arm assembly for deactivating an engine valve. A follower body pivots on a hydraulic lash adjuster, and engages a valve stem or lifter. The body receives a reciprocating member having a first and second rollers outboard of the body for following eccentrics of a cam lobe that straddles the body, the body having elongate openings on either side of the reciprocating member. A locking pin selectively locks and unlocks the body to the reciprocating member. The reciprocating member does not make contact with the cam lobe and functions only as a link between the latching mechanism and the rollers. The pin engages the reciprocating member by a latching spring and is disengaged by pressurized oil supplied through the hydraulic lash adjuster. Means is provided for limiting axial growth of the HLA during deactivation mode of the rocker arm assembly.

摘要： A two-step finger follower rocker arm assembly including a follower body having a socket at a first end for engaging a hydraulic lash adjuster and a pad at an opposite end for engaging a valve stem. A passage through the follower body in the direction of actuation by an engine cam lobe is slidingly receivable of a slider member for variably engaging a central cam lobe, preferably a high-lift lobe. An elongate shaft extends through a transverse bore in the slider member and through a slotted passage in the slider member. In the follower body, the shaft is provided with bearings supporting first and second lateral roller followers on opposite sides of the body for variably engaging first and second preferably low-lift lateral cam lobes flanking the central cam lobe. A lost-motion spring urges the slider member into contact with the central lobe. A latch member driven by a piston selectively locks the slider member to the follower body such that the follower follows the motion of the central cam lobe. When the latch member is disengaged from the slider member, the member slides within the follower body, allowing the lateral rollers to engage and follow the lateral cam lobes. Preferably, the latching mechanism is provided as a pre-assembled cartridge unit.

摘要： In a fuel-pumping system in an internal combustion engine, a mechanical fuel pump roller actuator is slidably disposed to ride on a dedicated tri-lobate camshaft lobe. In prior art camshaft lobes for this purpose, a portion of the lift profile over a certain angle of camshaft rotation imparts a constant velocity, and hence zero acceleration and zero jerk, to the roller actuator. It has been found that such areas of zero acceleration give rise to undesirably high contact stress between the lobe and the roller actuator. In a method in accordance with the present invention, a reference radius of curvature of a reference camshaft lobe lift profile is adjusted such that, between regions of minimum lift and maximum lift, there are no regions imparting zero acceleration to the actuator and maximum contact stress is reduced.

摘要： A camshaft has, for each valve lifter, a high lift cam between two low lift cams, the high lift cam fitting within the envelope of the low lift cams. The lifter comprises an outer tappet elongated in the direction of the camshaft and slidably mounted in an elongated bore in a cam carrier. The outer tappet is contacted by both low lift cams and operates two valves simultaneously. An elongated bore extending transverse of the outer tappet carries an elongated inner tappet which is contacted by the high lift cam. A hydraulically actuated locking mechanism couples the tappets for movement together for high lift operation and unlocks for low lift operation to allow the inner tappet to idle in the outer tappet.

摘要： A direct acting hydraulic valve lifter of the type that is reciprocably journaled as in the cylinder head of an internal combustion engine so as to be engaged by a cam on an engine driven camshaft to control opening and closing movement of an associate valve. The lifter includes a follower body having a circular outer tubular wall with an inner integral web closely adjacent to one end thereof that terminates at a stepped bored integral depending piston, the one end thereof being closed by a disk cam engaging foot which forms with the piston and a surface of the web a fluid reservoir. A baffle, fixed to the plunger and to inner surface of the tubular wall, defines an oil supply passage which is adapted to receive fluid via a side port in the tubular wall and to be in flow communication with the fluid reservoir via an aperture in the web. A cup-shaped, closed end cylinder member slidably encircles the plunger to form therewith a hydraulic lash adjuster having a pressure chamber therein. In one enbodiment, a mechanical retainer is operatively secured to the tubular wall whereby to retain the cylinder member in unit assembly on the plunger. In a preferred embodiment, lubricating oil in the pressure chamber and in a leak-down flow path between the cylinder member and plunger and a one-way ball valve controlling flow into the pressure chamber are operative to hold the cylinder member in unit assembly on the plunger.
