ABSTRACT:
A hydraulically operated valve train for an internal combustion engine wherein the valves are opened and closed by means of a fluid operated piston. The fluid piston is, in turn, operated by a remotely positioned actuator consisting of a reciprocating plunger and valve member that sequentially operates so as to seal off the portion of the fluid circuit between the plunger and the fluid piston and then actuate the valve through the fluid piston.
