Note: Texte fondé sur des processus automatiques de reconnaissance optique de caractères. Seule la version PDF a une valeur juridique
outflow surface of the outflow channel (12) of the valve cup (3) is 32°. Subsequently, a cleaning grate (9) is placed on the valve cup (3), fitting into the inner diameter of the retaining ring (11) . Lastly, a mirror or any other aesthetic variant can be placed, by aligning the fitting points between the lower part of the mirror and the retaining ring (11) .

The present description is of course in no way restricted to the embodiments presented in this document and a person with ordinary skill in this field could envisage many possibilities of modifying it without departing from the general idea, as defined in the claims. The preferred embodiments described above are obviously combinable with each other. Preferred embodiments are defined by the following claims.

CLAIMS

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), 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 outflow channel (12) of the valve cup (3) presents a slanted surface.

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

(8) along its base.

7. 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) .

8. 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.

9. The system according to any one of the preceding claims, characterized in that the valve cup (3) presents a residue retention chamber around the outflow channel (12) .

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

(9) mounted on its top.
