Abstract

Improvements in thermostats for refrigeration circuits, particularly of internal combustion engines, characterized by the fact that the body of the thermostat is made with a central cavity that defines three chambers that are substantially coaxial and communicating with each other, that is: a) a first end chamber that communicates with one of the inlet links and closed to the outside by a removable cover; b) a substantially cylindrical intermediate chamber and constantly linked to the other inlet link by means of an annular collector made in the corresponding cylindrical wall; c) a second end chamber, which communicates with the outlet link and has a cylindrical wall coaxial to the cylindrical wall of the intermediate chamber but which has a smaller diameter than that of the latter, and also due to the fact that the sealing means are constituted by a cylindrical sleeve mounted slidingly on the cylindrical wall of the intermediate chamber and joined by means of radial ribs to a central ring that forms the seat for the thermosensitive element, whose stem takes support against the removable cover that closes the first end chamber to the outside; a spring being housed inside the second end chamber, this spring being able to push the sleeve and the heat-sensitive element in the direction of the aforementioned removable cover; the axial length of the aforementioned cylindrical sleeve being chosen so that one of its edges rests against the aforementioned removable cover when the other edge leaves the communication between the aforementioned annular collector and the intermediate chamber completely free.
