The invention concerns a flow metering turbine comprising a tubular body (1) run through by the fluid to be measured (A) and housing: an upstream cross pin (2) and a downstream cross pin (3) each formed by a hub (21, 31) and fixed blades (22, 32), bearing the hub in the tubular body (1), the opposite surfaces (23, 33) of the hubs (2, 3) having a cavity (24, 34) in the axis (X-X) of the tubular body (1) for receiving a bearing/stop assembly (50, 51), a propeller (4) formed by a hub (41) bearing the blades (42) and an axle (44, 44A, 44B), located between the cross pins (2, 3), the ends (44A, 44B) of the axle being located in the bearings (50) of the cross pins (2, 3) and against the stops (51). The invention is characterised in that each cross pin (2, 3) hub (21, 31) is run through by at least one fluid channel (25, 35) opening into the cavity (24, 34) at right angle with the bearing/stop assembly (50, 51),
Turbine débitmétrique comprenant un corps tubulaire (1) traversé par le fluide
à mesurer (A) et logeant: un croisillon amont (2) et un croisillon aval (3)
formés chacun d'un moyeu (21, 31) et d'ailettes (22, 32) fixes, portant le
moyeu (21, 31) dans le corps tubulaire (1), les faces opposées (23, 33) des
moyeux (2, 3) ayant une cavité (24, 34) dans l'axe (X-X) du corps tubulaire
(1) pour recevoir un ensemble palier/butée (50, 51); une hélice (4) formée
d'un moyeu (41) portant des ailettes (42) et un axe (44, 44A, 44B), placée
entre les croisillons (2, 3), les extrémités (44A, 44B) de l'axe étant logées
dans les paliers (50) des croisillons (2, 3) contre les butées (51);
caractérisée en ce que chaque moyeu (21, 31) de croisillon (2, 3) est traversé
par au moins un canal de fluide (25, 35) débouchant dans la cavité (24, 34) au
droit de l'ensemble palier/butée (50, 51).
