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