ABSTRACT:
Oleodynamic distribution system, with separate control of the suction and exhaust valves, with continuous time setting of all running four-stroke-cycle engines. This distribution system uses specific profiled pumping element to generate suction phase and exhaust phase having this specific profile and having reduced the number of moving components it will be simple to adjust the timing of system for all speeds and engines without the need of changing components.
