Abstract
Improved hydraulic lifter, of the type comprising a hydraulic shock absorber and spring, related to respective telescopic tubes, essentially characterized in that the sealed hydraulic chamber encloses a piston, on which it rests, the expansion spring that keeps it separate from the upper end of the camera; the piston having an eccentric central groove that supports toothed portions of a collar, related to the sealed chamber through a longitudinal guide and a hydraulic valve-lower retention body against the expansion of the upper spring, mounted elastically on the piston rod which passes through the opposite end of the chamber, the portions of the toothed collar being anchored on the eccentric throat, selecting the interlock between the plunger and the hydraulic chamber, which has its lower end closed by a synthetic seal comprising a central hole for passage of the piston rod combined with O-rings retained by, a washer that expands the latter making a tight seal.
