(54)	Device for optimizing the flow of refrigerant fluid fed to an evaporator of a refrigeration circuit and acting as an expansion noise level reducer

(57) A device for optimizing, within a refrigeration circuit, the flow of refrigerant fluid fed to an evaporator via an expansion member (1) and for reducing the expansion noise level comprises a body (10) constructed of porous material and positioned in correspondence with a free end (5) of said expansion member (1) along the refrigerant fluid path towards the evaporator within a containing tube (3) for said member (1) positioned at the entry to said evaporator, said body (10) containing at least a portion (7) of said free end (5) and being fixed within said tube (3).
