Fluid outlet interface for personal watercraft

Abstract

The disclosure relates to a fluid outlet interface for a personal watercraft, so that the latter can collect and divert a very small portion of the fluid pressurized by said vehicle and thus create a sufficient Venturi effect to drive the emptying of the bilge of said vehicle. The disclosure also relates to a personal watercraft, or more generally any floating device delivering a pressurized fluid, comprising such an interface.

What is claimed is: 
     
         1 . An interface for cooperating with a fluid outlet of a personal watercraft pressurizing said fluid, said interface comprising:
 a front face arranged to cooperate with said fluid outlet;   a rear face opposite the front face;   a main opening extending through the interface from the front face to the rear face along a first axis, the main opening having dimensions and a shape compliant with dimensions and a shape of a section of said fluid outlet;   a hole extending from the front face to the rear face substantially parallel to the main opening, wherein the hole has a varying diameter along a length thereof; and   a passage extending substantially perpendicular to the main opening, wherein the passage is in fluid communication with the main opening and the hole.   
     
     
         2 . The interface according to  claim 1 , wherein the passage includes a shoulder proximate to the main opening. 
     
     
         3 . The interface according to  claim 2 , further comprising a grate affixed against the shoulder. 
     
     
         4 . The interface according to  claim 3 , wherein at least a portion of the passage is threaded to receive one or more tightening screws therein. 
     
     
         5 . The interface according to  claim 1 , further comprising a fluid ejector coupled to the hole and extending from the rear face. 
     
     
         6 . The interface according to  claim 5 , wherein the ejector defines a convergent cone therein and a divergent cone concentric to the convergent cone. 
     
     
         7 . The interface according to  claim 6 , wherein the ejector includes a tubular and hollow main body. 
     
     
         8 . The interface according to  claim 7 , wherein the ejector is threaded to engage the hole. 
     
     
         9 . The interface according to  claim 1 , wherein an inner wall of the ejector includes ribs.
