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.

摘要： A two-step roller finger follower assembly for use in conjunction with a camshaft of an internal combustion engine, wherein the camshaft has at least one first lobe and at least one second lobe. The roller finger follower assembly comprises a follower body for engaging the first cam lobe and having a central aperture, a follower pivotably disposed on the follower body in the central aperture for engaging the second cam lobe, and a limiting stop disposed on the follower body for engaging a feature on the follower to limit travel of the follower body with respect to the follower. The limiting stop prevents overtravel of the follower body during valve-deactivation mode of the assembly, thus preventing excessive leak down of an associated hydraulic lash adjuster.
