ABSTRACT:
An improved valve disabler control for a multi-cylinder engine having individually pivoted rocker arms and an intake and exhaust valve pair for each cylinder. Half of the valve pairs are provided with valve disablers having rotatable sleeves. Rotation of the sleeves counterclockwise (ccw) allows sliding movement of the rocker arm fulcrums, thereby disabling the valves; clockwise (cw) rotation of the sleeves prevents sliding movement of the fulcrums, thereby enabling the valves. The improved control includes a link and a spring interconnecting the disabler sleeves for each valve pair. Each link rotates the intake valve disabler sleeve ccw in response to ccw rotation of the exhaust valve disabling sleeve. A slot connecting each link to the intake valve disabler sleeve allows cw rotation of the exhaust valve disabler sleeve before cw rotation of the intake valve disabler sleeve. Each spring provides a cw biasing force to the sleeves. The biasing force increases in response to ccw rotation of the sleeves. Actuation of a second valve disabler pair in response to exhaust valve disabler actuation of a first valve disabler pair is provided by a spring-link and slot arrangement interconnecting the exhaust valve disabler sleeves of two valve pairs.
