Thermostatic Valve

Abstract: The invention relates to a valve comprising a one-piece housing (10) and a thermostatic element (20) made of a thermally expandable material, including a fixed portion (22) and a mobile portion (21). A first plug (30) is axially movable relative to a first seat (13) integrated into the housing between closed and open configurations in order to control the flow of fluid between first and second paths (1A, 1B) and is carried by the mobile portion in such a way that it moves the first plug by causing it to remain in the closed configuration when deployed below a predetermined stroke (?) and to move to an open configuration when deployed beyond that stroke. A second plug (40) is axially movable relative to a second seat (15) integrated into the housing and axially spaced apart from the first seat between closed and open configurations in order to control the flow of fluid between the first and a third (1C) path and is carried by the mobile portion in such a way that it moves the second plug from the closed configuration to the open configuration when deployed below the predetermined stroke. Moreover, in orthogonal projection on a geometric plane perpendicular to the axis, the first plug is inscribed inside the second seat.
