Abstract

Improved apparatus for controlling the regulation of the operating time of a mechanism in an internal combustión engine, the mechanism including a movable plunger that can be moved in an injection path and in a retraction path, and the engine including an actuator device to move the plunger, comprising an envelope having a perforation formed therein, first and second members movable in said perforation, said first member being connected to be moved by said actuator device, said second member being connected to move with said plunger, said members forming a time regulation chamber between them, a device for feeding a time regulating fluid to said time regulating chamber, said time regulating fluid forming a hydraulic link between said first and second members, and a device that responds to pressure, connected hydraulically only said time control chamber for releasing at least a portion of said time regulating fluid when the pressure acting on it reaches a predetermined level during said injection path.
