ABSTRACT:
Disclosed herein is a liquid separating and evacuating device for fluid suction equipment and, in particular, for dental surgery equipment, with which it is possible to separate the air from the liquids and to continuously drain the latter without interrupting the suction.
The said device consists essentially of a cylindrical container, placed on a vertical axis, that is provided on the bottom part thereof with a draining valve. Placed inside the said container there is a horizontal partition that is divided into two superposed chambers. This partition has a valve which either allows or prevents the liquid from passing from the first chamber to the second chamber.
A float contained in the first chamber controls, by actuating a pneumatic distributor, the opening and the closing of the aforementioned valves which successively allow the liquid to pass from the first chamber to the second chamber and from the latter to the outside.
