Patent ID: 6898981

Claim:
Device for measuring pressure at two points of a fluid flow, including: a frame ( 10 ) formed of two plates ( 12 , 14 ) each including two planar surfaces, one outer ( 12 a , 14 a ) and the other inner ( 12 b , 14 b ), the two inner surfaces being mounted on each other and wherein one of the plates ( 12 ) is provided with a recess ( 22 ) closed by the other plate ( 14 ) to form together two chambers ( 28 , 30 ) including two planar walls ( 24 , 14 b ) parallel to the surfaces ( 12 a , 14 a ) of the frame and a side wall ( 26 ) forming its periphery and a fluidic restrictor channel ( 32 ) connecting the chambers ( 28 , 30 ) to each other, said frame ( 10 ) including two apertures ( 34 ) respectively connecting the two chambers ( 28 , 30 ) to the exterior to allow a fluid to flow therein, and means ( 16 ) for supplying a measurement of the pressure in each of said chambers ( 28 , 30 ), characterized in that the side wall ( 26 ) of the two chambers ( 28 , 30 ) is shaped such that they are spindle-shaped.
