ABSTRACT:
A pulsating device is disclosed herein for interrupting the flow of water being discharged via a nozzle carried on a dental syringe. The device includes a body coupled between the syringe and the nozzle having a central cavity partially occupied by a flutter valve. The valve includes a broad, flat member pivotally carried at its mid-section in the cavity so as to interfere with a flow of water passing through the cavity from the syringe to the nozzle. One end of the member is weighted so that the member flutters across the ports of the syringe and the nozzle to interrupt the water flow in response to the incoming water pressure from the syringe.
