Electrohydraulic unit for actuating the valves of an endothermic engine |
摘要 |
An electrohydraulic unit for actuating the valves of an endothermic engine is provided with a hydraulic actuator for lifting a respective valve by means of a pressurized liquid and a spring antagonistic to the hydraulic actuator in order to close the valve and to discharge the liquid from the hydraulic actuator in the final closure phase of the valve through a discharge branch provided with a calibrated orifice to slow down the expulsion of the liquid and maintain a substantially constant closing velocity of the valve during discharge of the liquid from the hydraulic actuator.
