Abstract

A rotary frusto-conical gas tap comprises a housing formed with a gas inlet and a gas outlet, and a frusto- conical plug 14 which permits an increasing flow of gas through the housing from said inlet to said outlet as the plug is angularly turned progressively from an off position, the plug (14) being formed in its exterior surface with a plurality of elongated grooves (15, 16 and 17) and in its interior with a passage (18) connecting said outlet port, with grooves 15 and 16 via respective regulating holes (19 and 20), the third groove (17) communicating directly with said passage (18), each of said grooves (16, 17) beind displaced, relative to that groove which will have previously been in communication with the inlet port as the plug (14) is turned from its off position towards its fully on position, in a direction parallel to the rotational axis of the plug, and the leading end of each groove 16, 17, namely that end which will first communicate with said inlet port as the plug is turned from its off position towards its fully on position, overlapping the trailing end of that groove previously in communication with the inlet port. <IMAGE>
