Rocker arm adjustment screw assembly

An adjustment screw for a rocker arm of a combustion engine comprising:

• a vertical member having an upper end and a lower end, me upper end connected adjustably to the rocker arm, the vertical member oscillating in relation to the pivoting rocker arm, the vertical member having a radial port, an axial port and a circumferential groove, the radial port extended transversely through the vertical member, the axial port concentric to the vertical member and extended longitudinally from the radial member trough the lower end, 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, the axial port receiving oil from the radial port;
• 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, the bottom surface in continuous planar contact with a top surface of an actuator, the top surface movement being linear, and an aperture extended longitudinally through the lower member;
• and
• a pivotal connection formed by the snap fitted connection of the upper end of the lower member and the lower end of the vertical member, the pivotal connection having:
• a female socket engaged pivotally and rotationally to the male connector, the female socket having a female socket centerline, a trailing portion, a mid portion, and an engagement lip portion, the trailing portion axially trailing and connected to the mid portion, the mid portion axially trailing and connected to the engagement lip portion, the trailing portion having a leading surface and a leading annular surface, the leading surface centered about the female socket centerline, the leading annular surface disposed about and concentric to the leading surface, the mid portion having an inner wall extended axially through the mid portion and centered about the female socket centerline, the leading annular surface defined radially inward by a perimeter of the leading surface and radially outward by the inner wall of the mid portion, the engagement lip portion having an inner edge extended laterally and axially through the engagement lip portion and centered about the female socket centerline, the perimeter having a perimeter diameter less than an edge diameter of the inner edge,
• a male connector having a male connector centerline, a leading surface, an outer perimeter, and a trailing surface, the leading surface being convex and semi-hemispherical to mate pivotally and rotationally to the concave and curved leading surface of the female socket, the leading surface of the male connector defined by the outer perimeter, the outer perimeter centered about the mate connector defined by the outer perimeter, the outer perimeter centered about the male connector centerline and aligned axially to and disposed radially inward from the inner wall of the mid portion, the outer perimeter having a male connector diameter perpendicular to the male connector centerline, the male connector diameter greater than the edge diameter of the inner edge of the engagement lip portion, the trailing surface disposed radially outward and tapered radially inward from the outer perimeter in the axial trailing direction, tie trailing surface centered about the male connector centerline, the inner edge of the engagement lip aligned axially to and disposed radially outward of the trailing surface, and
• a cavity defined by the leading surface of the trailing portion of the female socket and a flat surface of the leading surface of the male connector, the flat surface radially inward and concentric to the leading surface of the male connector, the axial port providing oil to the cavity,
• wherein the aperture in the lower member is in communication with the top surface of the actuator and the cavity, the cavity providing oil to the aperture, the aperture providing oil to the top surface of the actuator.
