    摘要: A rocker assembly has a first arm for following a first or opening camshaft lobe, a second arm for following a second or closing camshaft lobe, and a pivot axis of the rocker arm therebetween. A captive roller follower on the first arm follows the first lobe, and a slider on the second arm follows the second lobe. An eccentric pivot pin for the rocker assembly is rotatable to change the location of the pivot axis of the rocker assembly with respect to the captive roller and the slider, to adjustably set mechanical lash among these components after installation of the rocker arm assembly into a variable valve mechanism of an internal combustion engine.

    摘要: A method for automatically setting valve clearances in internal combustion engines (also known as "tappet setting" or "valve lash setting") comprises a series of steps in which a rocker arm (10) is set to a zero position which is recorded as a reference datum and an adjustment screw (18) is then operated to set the rocker arm to a first reference position. The adjustment screw is then rotated through a predetermined angle so that the rocker arm is moved to a second reference position. The difference between the first and second reference positions and the predetermined angle are used to determine a coefficient relating the angular movement of the adjustment screw to linear movement of the rocker arm. The coefficient is then used to calculate the angular rotation of the adjustment screw required to set a predetermined valve clearance relative to the zero position. The initial adjustment of the rocker arm position serves to neutralise backlash in the valve drive train prior to setting the valve clearance.

    摘要: Zur Ventilspielbeseitigung ist ein Kipphebel (2) auf einer dreh­festen Schwenkachse (3) unter reibschlüssiger Zwischenführung einer Exzenterscheibe (9) und einer Buchse (14) gelagert, die in einer Ausnehmung (15) mit begrenztem Spiel einen radialen Anschlag (16) an der drehfest gelagerten Schwenkachse (3) aufnimmt, wobei die Exzenterscheibe (9) über die in Umfangsrichtung wirksame Feder (11) mit der Schwenkachse (3) in Verbindung steht. Die Exzentrizität (e) der Exzenterscheibe (9) ist so gewählt, daß während des Betätigungshubs des Ventils nach Berührung zwischen einem der Ränder (18) der Ausnehmung (15) und dem Anschlag (16) eine Verringerung des Übersetzungsverhältnisses des Kipphebels (2), dagegen nach Rückkehr des Ventils in seine Schließstellung und Fortfall der Übertragungskräfte durch die Feder (11) ein Schwenken der Exzenterscheibe (9) bis zur Beseitigung des Ventil­spiels erfolgt.
