Patent ID: 7509979

Claim:
A device for slowing down and disintegrating a plug of liquid plunging forward in a duct, comprising: a container ( 1 ) having a bottom ( 5 ) and an opposite inlet ( 2 ), which is connectable to the duct and through which the plug or liquid can be directed into a central, axial trajectory in the container, that inside the container an inner tube ( 7 ) being open towards the bottom ( 5 ) is arranged, which tube separates an inner hollow space ( 8 ) from an outer, cross-section-wise ring-shaped hollow space ( 9 ), that in a trajectory of the entering plug of liquid a distributor body ( 13 , 13 a ) is arranged in the bottom of the container for splitting and disintegrating the plug of liquid as well as throwing out the disintegrated constituent parts of liquid in a direction outwards from the centre, the distributor body ( 13 , 13 a ) having a shape that tapers in a direction against a flow of the entering plug of liquid, and that the bottom ( 5 ) comprises a concavely curved guide surface ( 16 ) configured for diverting the liquid from one of the hollow spaces to the other one in order to, in this way, reverse a direction of motion of the liquid.
