Abstract
Closes perfected hydraulic doors essentially characterized in that it comprises control arms articulated to each other and one of them linked to a piston that meshes like a rack with a piston able to move inside a hydraulic chamber defined inside the body of the door closer against a spring whose regulation determines a greater or lesser closing thrust, the piston carrying a valve that defines a passage between it and the piston where oil drains from one part of the chamber to the other in the opening of the door, but that in the closing is sealed by 1a''valve; in the body is housed an injector tube on which the valve is moved and which has an axial hole and two radial holes, one in which it can be regulated by a screw to vary the closing speed and the other susceptible to be sealed by the valve in the closing operation so that it is verified slowly.
