Patent ID: 7143992

Claim:
A device for regulating and stabilizing a flow of a fluid adapted for insertion in a pipe for passage of the fluid ( 3 ), said device (RF) comprising a single body ( 20 ) and an elastic flow regulating means ( 26 ), said single body ( 20 ) having at least: one inlet (SI), having a first section; a section narrowing ( 22 A) downstream of said inlet (SI) and said flow-regulating means ( 26 ); and supporting means ( 24 , 25 ), for supporting said flow-regulating means ( 26 ) upstream of said narrowing ( 22 A); wherein said single body ( 20 ) further defines, downstream of said narrowing ( 22 A) and said flow-regulating means ( 26 ), a chamber (S) having a cross section smaller than that of said inlet (SI), said chamber (S) having at the longitudinal end thereof opposite to said flow-regulating means ( 26 ), bottom wall ( 23 ), wherein a peripheral wall ( 21 ) of said single body ( 20 ) surrounds at least partly said flow-regulating means ( 26 ), at least a part of an outer edge peripheral of said flow-regulating means ( 26 ) being spaced apart from an inner surface of said peripheral wall ( 21 ), to define therebetween an inlet passage for the fluid, wherein said flow-regulating means ( 26 ) are at least partially spaced apart from said narrowing ( 22 A), in an axial direction of said single body ( 20 ), to define therebetween a path connecting said inlet passage with said chamber (S), and wherein said chamber (S) is provided with a plurality of outlet passages ( 28 ) having a section smaller than that of said chamber (S).
