HYDRAULIC DEVICE FOR THE THERMO-PNEUMATIC INSULATION AND OPTIONAL AGITATION OF THE CONTENTS OF AN OPERATIVE CAVITY

摘要

The invention relates to hydraulic device (1) produced from one or several components, for example from a support (12) comprising: an operative cavity (3), at least two ducts (41, 42), for example an inlet (41) and outlet (42) for a liquid of interest which communicate with said operative cavity (3), at least two valve bodies (51, 52) with no moving pieces for control of said cavity. The above is characterised in that said device further comprises two trapping chambers (81, 82) for a gas, for example, air, in communication only and respectively with the two ducts (41, 42), by means of two connecting channels (91, 92) respectively, both pertaining to thermal exchange with a heat source (21, 22).
