Zusammenfassung:The invention relates to a mixed solar actuator designed on the heliothermal-mechanical conversion principle. According to the invention, the actuator consists of a first thermo-mechanical converter represented by a thermo-bimetallic tape (1) shaped according to a helical cylindrical path, placed inside a cylindrical recipient (2) made of brass, together with another thermo-mechanical converter (3), with paraffin and piston, mounted concentrically in relation to the first one, both converters (1 and 3) being immersed in a thermally conductive paraffin medium (4), which occupies the interior of the recipient (2) and which enables the solar-origin heat transfer from the wall of the recipient (2) towards the two converters (1 and 3), the volume variations of the thermally conductive medium (4) being compensated by means of an assembly of two Bourdon tubes (5 and 5') coaxially mounted, and connected and fixed by means of some collecting channels (6 and 6') to the recipient (2), the two Bourdon tubes (5 and 5') having the role of a supplementary paraffin converter, which, by means of some rods (18 and 18') with roll and spring, by taking over the paraffin volume variations, undergo a deformation towards the exterior, thus generating force and movement. Invenţia se referă la un actuator solar mixt, conceput pe principiul conversiei heliotermomecanice. Actuatorul conform invenţiei este constituit dintr-un prim convertor termomecanic, reprezentat printr-o bandă (1) termobimetalică modelată după un traseu cilindric elicoidal, plasată în interiorul unui recipient (2) cilindric, realizat din alamă, împreună cu un alt convertor (3) termomecanic, cu parafină şi piston, montat concentric în raport cu primul, ambele convertoare (1 şi 3) fiind imersate într-un mediu (4) termoconductor din parafină, care ocupă interiorul recipientului (2) şi care facilitează transferul căldurii de origine solară, de la peretele recipientului (2), către cele două convertoare (1 şi 3), variaţiile de volum ale mediului (4) termoconductor fiind compensate prin intermediul unui ansamblu de două tuburi (5 şi 5') Bourdon, montate coaxial, şi racordate şi fixate prin intermediul unor canale (6 şi 6') colectoare la recipient (2); cele două tuburi (5 şi 5') Bourdon îndeplinesc rolul unui alt convertor cu parafină, care, prin intermediul unor tije (18 şi 18') cu rolă şi resort, preluând variaţiile de volum ale parafinei, se deformează spre exterior, generând astfel forţă şi deplasare.
