Abstract:
An adjustment screw assembly for a combustion engine comprising:a rocker arm having a rocker arm end; a shaft, the rocker art pivoting about the shaft, the rocker arm end disposed radially outward from the shaft, a vertical member having an upper end and a lower end, the upper end connected adjustably to the rocker arm end of the rocker arm, a radial port and an axial port, the radial port extended transversely through the vertical member, the radial port receiving oil from the rocker arm, the axial port concentric to the vertical member and extended longitudinally from the radial port through the lower end, the axial port receiving oil from the radial port, and a circumferential groove, the circumferential groove aligned axially and in communication with the radial port ends, the circumferential groove receiving oil from the rocker arm, the radial port receiving oil from the circumferential groove; and a lower member disposed below the vertical member, the lower member having an upper end and a bottom surface, the upper end snap fitted and thereby connected pivotally and rotationally to the lower end of the vertical member forming a pivotal connection, whereby a top surface of an actuator is in continuous planar contact with the bottom surface of the lower member while the rocker arm causes the vertical member to oscillate and the actuator to move linearly up and down, the bottom surface sliding back and forth transversely across the top surface as the actuator moves up and down.
