The invention relates to a valve for bottles of liquified petroleum gases. Object of the invention is it to provide valves which enable a larger gas admission flow inside the bottle by keeping the exit flow constant. To solve this object the shape of the valve is defined by a nearly cylindrical body (1) having an upper section with a hollow cylindrical mouth (4) inside which an opening is defined by a hollow cylindrical boss allowing the entrance to a nearly cylindrical inner space housing two rams (10; 11, 12, 23) one of them (10) is external and approximately cylindrical and the other has two outer cylindrical subsections (11, 23) and an intermediate prismatic body (12) an further having a lower section, crowned by a fixing hex-nut having on one of its sides a safety valve (15) lowerly followed by a truncated cone like subsection reversed with the revolution surface (21), threaded, a lower mouth (22) allowing access to a wide cavity. <IMAGE> |
