<p>A thermostatic head for controlling a fluidodynamic system comprises a thermostatic motor (11) fastened to a tubular body (30) to be coupled with a support sleeve (40), coaxial with said body (30), said sleeve being in its turn apt to be coupled with the system. The tubular body (30) can rotate with respect to said sleeve (40) and is axially movable in both senses with respect to the latter; interference means are provided on the thermostatic head so as to block the bubular body and the sleeve one with respect to the other during rotation. These interference means comprise first blocking means (32) associated inside to the tubular body (30)and second blocking means (43) associated inside to the sleeve (40) said first and second blocking means being alternatively apt to be associated and dissociated one with respect to the other so as to activate and de-activate, respectively, said block during rotation.</p> |
