Abstract
Improved hydraulic lifter, especially applicable to table shafts and the like, of the type comprising a telescopic spring-loaded extensible system, combined with "a hydraulic damper whose piston dampens the action of the spring, characterized essentially because the tubular body in whose interior houses the spring and hydraulic shock absorber, externally coupled paths washers provided with notches that slide by a guide integral with the tubular body surrounding the shaft, with at least one of the intermediate washers being eccentric with respect to the wrapped tubular body which freely rotates on an equally eccentric bushing, integral with this last tubular body, so that the rotation of the wrapped tubular body to which the board engages, laterally displaces the eccentric washer, fixing the relative position between the enveloping and wrapped bodies.
