Abstract
Stopcock with safety valve comprising, in combination; a first hollow body with an inlet and outlet passage for the circulating liquid between which it has a valve seat; a second tubular body that adapts to thread on the first body; a plug that fits over the free end of said second body by closing it; a sliding core housed inside said body comprising said core at one of its ends, a widened lining by a sensibly elastic disk forming a valve facing the seat formed between the entry and exit passages of the first body; an axial spindle mechanically related to the said sliding core and extending from outside, through the plug closing the second hollow body, to receive a handle or actuating knob to make the sliding core slide and with it the valve before the seat of the first egg body and a bellows that intervenes as an expansion spring acting on said valve with a tendency to bring it to the closing situation.
