Abstract
A mechanically simplified electric and fluid (gas, vapor or liquid) control for a piston engine, including an engine valve actuator system that eliminates rotating cam shafts and heavy internal combustion engine valve closing springs by using an electromagnet and an armature which is attracted by the electromagnet to initiate movement of both a fluid control valve and the engine valve. When the control valve is moved only slightly off its seat by the armature, fluid pressure instantly drives the control valve a much greater distance closing the engine valve. Opening and closing time is regulated independently. Engine valves are opened by reversing the fluid pressure balance across the control valve at the time selected.
