ABSTRACT:
A device for disabling a poppet valve in an internal combustion engine. The engine includes a valve actuating drive train having an overhead camshaft, a hydraulic lash adjuster, and a rocker arm which pivots at one end about the lash adjuster. The disabling device is secured to the valve stem and is drivingly interposed between the valve and the other end of the rocker arm. The disabling device includes a cap and drum or first drive means moveable with the rocker arm and relative to the valve stem, first and second springs concentric to the valve stem and respectively apply a biasing force to the first and second drive means and a rotatable latch. The latch is moveable between a valve enabling position and a valve disabling position. The valve is enabled for normal opening and closing when the latch is in the valve enabling position; in this position the latch prevents relative movement between the first and second drive means and both springs bias the valve closed. The valve is disabled when the latch is in the valve disabling position, in this position the latch allows relative movement between the first and second drive means and the first spring biases the first drive means into contact with the rocker arm and the second spring biases the valve closed.
