Abstract
Improvements in cylinder deactivating devices for internal combustión engines, of the type comprising a block and an engine head, a plurality of engine cylinders in the block, intake and exhaust valves for each engine cylinder spring-loaded to their positions closed, a valve train associated with cams that operates each of the valves, characterized in that the valve train is provided with a rocker arm that has an opening in its middle section that allows the rocker to be oscillatingly connected to a first short pin of mounting extended upwards from the motor head, pressing one end of the rocker arm against a spiral spring which normally holds the valve closed and the other end of the rocker arm receives the upper part of a push rod; hydraulic means for varying the position of the fulcrum on the first short pin around which the rocker arm oscillates, the hydraulic means comprising a tubular sleeve having the short pin extended upwardly therein, the upper part of the tubular sleeve having an area of transfer of force of pressure; a hydraulic cylinder having integral side walls that extend continuously along the entire length of the hydraulic cylinder from the base to its upper part with the hydraulic cylinder having an upper wall that closes the end of the cylinder, a piston mounted with reciprocating movement inside the hydraulic cylinder and forms a sealed chamber between its upper surface and the interior of the hydraulic cylinder, the hydraulic cylinder has a lower wall that closes the end of the cylinder, the lower wall having a plurality of through holes passing through it within which a plurality is inserted. Of force transfer bolts, the lower ends of the force bolts are supported on the force transfer surface of the tubular sleeve by forming the upper ends of the bolts pressure contact surfaces against which the piston is forced when the hydraulic fluid under pressure enter the chamber sealed in the hydraulic cylinder to activate the valve train to reactivate the engine cylinder; a fluid pressure member having a source of hydraulic fluid under pressure connected to the chamber sealed in the hydraulic cylinder by at least one tube and control valves in the fluid pressure device to control the hydraulic force exerted against the top of the piston in said hydraulic cylinder.
