Abstract
The present invention is concerned with a vacuum release suction device for regulating and controlling suction in an aspiration line, and which may be included in aspirators such as for example dentistry, surgery, or cosmetic tools. When operated, such tools generally generate noise which may become harmful to the tool user or for the patient on which the tool is used. More specifically, the suction device of the present invention includes a body having an inlet port and an outlet port defining a chamber in the body and a bypass inlet intersecting the chamber at an acute angle with respect to the longitudinal axis of the chamber, such that a main fluid stream is generated with minimized occurrences of flow separation, turbulence and therefore minimized generated aerodynamic noise.
