Abstract (en)
[origin: EP1715264A1] The device has a body, traversed by a coolant, comprising an inlet compartment (1210), in which the coolant enters, and an outlet compartment (1230), through which the coolant leaves the body. A set of expansion units comprises variable and fixed expansion units. The variable unit has an orifice (34) and a needle (134) varying the passage section of the orifice (34) according to the pressure of the coolant. The fixed unit has an orifice (35) with a fixed passage section. The expansion units allow the coolant to pass from the inlet compartment to the outlet compartment through the orifices.
