Abstract

The valve includes a housing, a thermostatic element, a first shutter displaced by the thermostatic element along an axis relative to a first seat integrated into the housing to control a flow of fluid between the first and second paths, a cage, a first return spring, a second shutter axially displaced by the thermostatic element relative to a second shutter axially displaced by the thermostatic element with respect to a second seat integrated into the cage, a third shutter axially displaced by the fluid overpressure in the second path relative to a third seat integral with the cage, and a second return spring. The cage includes a tubular part, which is centred on the axis and through the interior of which fluid flows between the second and third paths. An outer face of the tubular part is provided with a seal. The cage also includes arms.
