    摘要： A tappet assembly for use in the valve train of an automotive type internal combustion engine has a roller at one end adapted to be engaged by the cam lobe of a camshaft for that engine. A spring biased piston is incorporated in the assembly for movement into frictional engagement with the roller at low engine speeds to dampen out vibrational or shaking forces present in the engine at this speed level by increasing the resistance to rotation of the roller. At higher engine speeds, the piston is moved progressively away from frictional contact with the roller by engine oil galley oil pressure, which increases with engine speed, to a point where the piston is completely removed from engagement with the roller and the roller is permitted to freely rotate at a point when the engine vibration or shaking forces are no longer present.

    摘要： A sintered ferrous alloy which is high in wear resistance and relatively weak in the tendency to abrade another metal material with which the sintered alloy makes rubbing contact and suitable for rocker arm tips in automotive engines for example. The sintered alloy is produced by compacting and sintering a powder mixture of 15-50 parts by weight of a Fe-Cr-B alloy powder, which contains 10-35% of Cr and 1.0-2.5% of B, 1.0-3.5 parts by weight of graphite powder, such an amount of a Cu-P alloy powder that the powder mixture contains 0.2-1.5% of P and 1.0-20.0% of Cu and the balance of an iron powder.

    摘要： A guide (28) is provided for retrofitting an existing internal combustion engine block (10) with roller cam followers (24 and 26) in place of conventional barrel-type lifters, without modification of the block itself. The guide includes a guide bar (64), keyed to the upper body (38) of each follower to allow limited rotational freedom thereof and a resilient C-shaped spring clip (70) which simultaneously bears downwardly on the upper surface of the guide bar and upwardly on the lower surface (40) of an engine block boss (18) defining follower receiving bores (20 and 22). Annular spacers (72) are provided, if required, to displace the guide bar upwardly from the upper surface (52) of the boss. An upper leg (76) of the spring clip wraps around the guide bar for retention therewith and a lower leg (78) of the spring clip is necked at a point (86) intermediate adjacent cylindrical portions (30 and 32) of the follower boss for retention therebetween.
