Title (EN) THREE ROLLER ROCKER ARM WITH OUTBOARD LOST MOTION SPRING
(FR) CULBUTEUR À TROIS ROULEAUX AVEC RESSORT DE MOUVEMENT À PERTE HORS-BORD
Abstract:
(EN) A rocker arm can comprise a first outer arm and a second outer arm joined by a pivot body. An actuatable latch mechanism is within the pivot body. An inner arm assembly comprises a latch arm. A first spring prop is on the inner arm assembly distal from the latch arm. An axle joins the inner arm assembly to pivot between the first outer arm and the second outer arm. A spring is biased against the first outer arm and against the first spring prop. The first spring prop can comprise a hooked end. Or, the first spring prop can extend laterally out from the rocker arm and parallel to the axle. The spring can comprise a one-piece spring comprising first and second coil springs connected by a lateral connector. Or, two separate torsion springs can comprising tangential spring ends extending at approximately 90 degrees.
(FR) L'invention concerne un culbuteur qui peut comprendre un premier bras externe et un second bras externe joints par un corps de pivot. Un mécanisme de verrouillage actionnable est à l'intérieur du corps de pivot. Un ensemble bras interne comprend un bras de verrouillage. Un premier support de ressort est sur l'ensemble bras interne distal par rapport au bras de verrouillage. Un axe relie l'ensemble bras interne à un pivotement entre le premier bras externe et le second bras externe. Un ressort est sollicité contre le premier bras externe et contre le premier support de ressort. Le premier support de ressort peut comprendre une extrémité en crochet, ou peut s'étendre latéralement à l'extérieur du culbuteur et parallèle à l'axe. Le ressort peut comprendre un ressort monobloc comprenant des premier et second ressorts hélicoïdaux reliés par un connecteur latéral. Deux ressorts de torsion séparés peuvent comprendre des extrémités de ressort tangentielles s'étendant à environ 90 degrés.
