Abstract
Un primer balancín se soporta por un eje de balancín y se provee para poder operar una válvula. Un segundo balancín se soporta por el eje de balancín y se monta para alinearse con el primer balancín en la dirección axial de un árbol de levas. Un pasador selector puede moverse en la dirección axial del árbol de levas y conecta el primer balancín y el segundo balancín en una primera posición y oscila junto con el primer balancín y el segundo balancín. El pasador selector se posiciona en un lado del extremo de la válvula con respecto al eje de balancín, cuando se observa desde la dirección axial del árbol de levas.A first rocker is supported by a rocker and is provided to operate a valve. A second rocker is supported by the rocker and is mounted to align with the first rocker in the axial direction of a camshaft. A selector pin can move in the axial direction of the camshaft and connects the first rocker and the second rocker in a first position and oscillates together with the first rocker and the second rocker. The selector pin is positioned on one side of the end of the valve with respect to the rocker, when viewed from the axial direction of the camshaft.
