A TELESCOPIC ACTUATOR WITH A MAIN ROD AND AN AUXILIARY ROD AND A METHOD MAKING USE THEREOF

摘要

The invention relates to a telescopic actuator comprising a cylinder (1) in which a main rod (2) is mounted to slide telescopically along a sliding axis (X) between a retracted position and an extended position. The actuator includes an auxiliary rod (20) mounted to slide telescopically in the main rod along said sliding axis between a retracted position and an extended position, the actuator including controlled retaining means (30, 31, 32, 33) for retaining the auxiliary rod in the retracted position inside the main rod.
