<p>The separator and discharger device for waste fluids in dental plants comprises a separator chamber (2) internally of which a depression is created. A cannula aspirating fluids from a patient's mouth is connected to the separator chamber (2). Aspirated liquids are discharged into a bottom of the chamber (2) and then removed by means of a drainage pump (9), while air sent into the separator chamber (2) is extracted from an upper part of the chamber (2). The drainage pump (9), downstream of which a single-acting valve (13) is located, is started up when a liquid level in the chamber (2) reaches a predetermined level. The drainage pump (9) is always started up in a state of full immersion in the liquid, even when the single-acting valve (13) is malfunctioning. <IMAGE></p> |
