AMENDED CLAIMS

received by the International Bureau on 28 January 2019 (28.01.19)

1. A fluid outflow system characterized by comprising:

— an enveloping body (1) that comprises an oval-shaped outlet channel (2);

— a valve cup (3), inserted inside the enveloping body (1), comprising an outflow channel (12) presenting a slanted surface in relation to the vertical axis of the valve cup and a residue retention chamber around said valve cup (3), on the base of which a command tab (4) is fastened; said tab being activated by a counterweight mechanism that comprises a weight (6) placed at one end of the tab (4) and that promotes the tilting of the opposite end, namely, a closing surface (5), by way of the force exerted by the fluid contacting said closing surface ( 5 ) ,

wherein the weight (6) of the counterweight mechanism has a mass that favors the retention of a fluid film on the surface of the closing surface (5) .

2. The system according to the preceding claim characterized in that the valve cup (3) is fastened inside the enveloping body (1), by means of lock-snap mechanisms, in the position that aligns the outflow channel (12) of the valve cup with the outlet channel (2) of the enveloping body.

3. The system according to any one of the preceding claims, characterized by additionally comprising a retaining ring (11) .

4. The system according to any one of the preceding claims, characterized by additionally comprising a seal (10) .

5. The system according to any one of the preceding claims, characterized in that the valve cup (3) presents a frieze

(8) along its base.

6. The system according to any one of the preceding claims, characterized in that the closing surface (5) of the command tab (4) presents a side rim (7) .

7. The system according to any one of the preceding claims, characterized in that the command tab (4) is fastened to the base of the valve cup (3) by sideward quick fit.

8. The system according to any one of the preceding claims, characterized in that the valve cup presents a cleaning grate
