Patent ID: 8312902

Claim:
A filling head with low Reynolds number, of the type intended to fill liquids or fluids in corresponding containers by means of both a linear and rotary filler, comprising an inner body and an outer body, in which one moves axially with respect to the other, there being a space delimited between them forming a fluid passage zone subdivided into five zones: a damping zone A having an inlet, a pressure-loss zone B having a seated valve containing an outlet through which extends the inner body, a zone C with low Reynolds number, an acceleration zone D, and a nozzle or closure zone E, wherein: the damping zone A has a volume in the order of 50% or greater than the volume enclosed between the outer body and the inner body; the pressure-loss zone B is designed to obtain a velocity curve during the closing and the opening of the nozzle, wherein the diameter of the inner body varies along the pressure-loss zone B, so that the slope of the velocity curve decreases continuously as the seated valve closes, more quickly at the beginning and more slowly at the end; the inner body along the acceleration zone D and the closure zone E has an ogive shape; and the acceleration zone D is designed to achieve a constant acceleration of the fluid along zone D, wherein the annular section of the fluid passage varies along zone D so that the velocity in zone D increases linearly; and the zone C with low Reynolds number comprises a plurality of fins defining a same number n of channels between the fins for the passage of liquid or fluid, wherein the geometry of the filling head is defined by a characteristic coefficient that follows the expression: LRHC = 1 2 ⁢ D ext_C 2 - D int_C 2 ( 1 + n π ) ⁢ D ext_C + ( 1 - n π ) ⁢ D int_C wherein LRHC is the characteristic coefficient of the geometry of the filling head, being LRHC less than 4; D int — C is the diameter of the inner body in the zone C with low Reynolds number; D ext — C is the inner diameter of the outer body in zone C with low Reynolds number; n is the number of fins and channels, greater than 3; wherein zone C has a length necessary to be able to break the fluid turbulence.
