ABSTRACT:
This invention relates to an hydraulic actuation system for poppet valves of internal combustion engines. In substance, the system replaces the valve guide and spring assemblies of conventional mechanisms with miniature hydraulic actuators wherein the valve stem now serves as the actuator shaft and the valve guide as the actuator body. The valve actuators are remotely driven in push-pull fashion by fluid supplied by complementary cam followers. As such, interconnecting hydraulic lines replace the push rods and rocker arms of conventional valve driven mechanisms.
