Abstract

Hydraulic closure for doors essentially characterized by the fact that it comprises a fluid-containing cylinder provided with means for fixing it to the door leaf and provided inside with a piston that has a rack-like tooth on its side surface. For its engagement in the piston of a transverse axis connected to the fixed part of the door through a suitable articulated brace, said piston being provided in a hollow form and backed by an expansive spring which places it in its rest position towards one end of the cylinder, said piston being provided with a unidirectional valve that opens when the spring is compressed by the piston, and there is also a centered passage in said piston for a hollow rod provided with orifices for passing the fluid, located these orifices along the stem and one of them presenting its section adjustable by needle valve to achieve a certain speed of return of the piston, whose the speed is variable as it covers the orifices, thus achieving different closing speeds of the door.
