Abstract
Hydraulic retainer, perfected, especially for doors, essentially characterized in that it is constituted by a hydraulic chamber, from which protrudes a rotating rod, which has inside said chamber a radial extension on which eccentrically articulates a connecting rod that relates to a plunger which has a central duct sealed by a ball valve, while the internal side surface of said chamber has a longitudinal slit decreasing for hydraulic circulation, so that the rotation of the protruding stem given by the opening of the door transmits a displacement to the piston that is governed in its return path by the valve system combined with the forced circulation of the liquid through the slit established in the sealed chamber determining the retained closure of the door.
