Abstract
A hydraulically operated valve control system includes a hydraulic flow divider including a hydraulic valve adapted to distribute, between two lines feeding respectively to actuators coupled to two inlet or outlet valves of a cylinder, the flow of oil coming either from a source of oil under pressure or from the feeding lines. The oil flow is distributed between the two feeding lines on the basis of the ratio of oil flow-rates in these two lines.
