The thermostatic element (36) includes a cup (38) and a piston (40) that is movable in translation along an axis under the effect of the expansion of a thermodilatable material contained in the cup. To limit the size of the valve incorporating this element, and also to improve its reliability and making it easier to assemble, the thermostatic element includes a sheath (42) for guiding the piston (40) in translation, which sheath is held stationary relative to the cup (38) and defines internally a fluid flow passage (46) having one end (48) directed towards the cup that is open transversely to the outside of the sheath and that is adapted to be connected to a fluid access, and a second end (54) remote from the cup that is open axially and be shut by a shutter (50) carried by the piston.
