Low-bulkiness hydraulic hinge
First Claim
1. A hydraulic hinge for rotatably moving and controlling a closing element anchored to a stationary support structure between an open position and a closed position, the hydraulic hinge comprising:
- a hinge body anchorable to one of the stationary support structure or the closing element, the hinge body internally comprising a working chamber with a front wall and a bottom wall faced thereto;
a pivot defining a first longitudinal axis anchorable to the other one of the stationary support structure or the closing element, the pivot and the hinge body being reciprocally coupled to each other to rotate about a first axis between the open position and the closed position of the closing element;
a slider slidably movable within the working chamber along a second axis between a position distal from the bottom wall and a position proximal thereto, the pivot and the slider being reciprocally coupled so that a rotation of the closing element about the first axis corresponds to the at least partial sliding of the slider along the second axis;
a hydraulic damping system acting on the slider to hydraulically damp a movement of the closing element during opening or closing, the hydraulic damping system including a working fluid flowing in a hydraulic circuit; and
a separation element inserted into the hydraulic circuit to divide the hydraulic circuit in at least one first and one second variable volume compartments fluidly communicating with each other,wherein the separation element includes at least one calibrated opening to put in fluid communication the at least one first compartment and at least one second compartment and a pin passing therethrough, the at least one calibrated opening being defined by an interspace between the separation element and the pin.

Abstract
A hinge for cold rooms or glass shutters includes a stationary support structure and a shutter movable between an open position and a closed position. The hinge includes a hinge body with a working chamber; a pivot coupled with the hinge body; a cam element unitary with the pivot; a plunger element sliding in the working chamber, the plunger element having a slider with an operative face interacting with the cam element; a counteracting elastic member acting on the plunger element to move it between a position proximal to the bottom wall of the working chamber and a position distal therefrom. The hinge body has a substantially plate-like shape. The cam element includes an elongated appendix extending from the pivot to come in contact engagement with the operative face of the slider. The pivot is placed at one of the side walls of the working chamber.
