<p>The invention relates to a drain, comprising:
- a first chamber with an inflow opening in gravitational direction in the vicinity of the top side and an outlet opening in the vicinity of the underside;
- a second chamber with an inlet opening in gravitational direction in the vicinity of the underside which is in liquid connection with the outlet opening of the first chamber, and with an outflow opening in the vicinity of the top side,
wherein
as seen in gravitational direction between the outflow opening and the higher opening of the outlet opening and inlet opening, the volume in the first chamber is smaller than the volume in the second chamber.</p> |
