Abstract: A rotatable device includes a vent port, a siphon and a ballast chamber. The siphon has a crest positioned radially outwards of the vent port with respect to the rotational axis. The ballast chamber has a first outlet connected to the vent port and a second outlet connected to an inlet of the siphon. The first outlet of the ballast chamber is positioned radially inwards of the second outlet of the ballast chamber and radially outwards of the crest of the siphon with respect to the rotational axis. As such, the first outlet of the ballast chamber divides the ballast chamber into an unvented ballast portion radially inwards of the first outlet and a vented ballast portion radially outwards of the first outlet, and thus decouples the pressure change inside the ballast chamber from the radial position of the siphon inlet at the ballast chamber.
