초록 ▼

A dental syringe is connectible to sources of air and water under pressure for selectively providing a solid stream of water, a jet of air or a spray of water and air. The maximum rate flow of air and/or water to be used is independently metered in the handle portion of the syringe to limit the flow as required by the dental work being performed. Valve assemblies in the valve body porton of the syringe for independently controlling the air and water flow have respective actuator means each of which is interconnected with the valve assembly therefor to pull back into the water passage system downstream of the valve assembly any wafter that may be adjacent to the orifice of the syringe when the water flow is interrupted.

대표청구항 ▼

A dental syringe including: (a) a handle portion and a tip portion interconnected by a valve body portion, (b) a liquid passage means extending through said syringe having a discharge orifice at the free end of said tip portion, (c) said valve body portion formed with a valve assembly receiving cavity interposed in said passage means having a liquid inlet and a liquid outlet, (d) a valve assembly having a valve seat intermediate said inlet and outlet, said cavity having a liquid receiving chamber and a liquid discharge chamber at opposite sides of said valve seat, (e) a valve member including a valve head in said liquid receiving chamber and a stem member projected through said valve seat into said liquid discharge chamber, (f) bias means for urging said valve head against said valve seat, (g) manual actuating means extending into said cavity in axial alignment with said stem member having a liquid displacement member movable into said liquid discharge chamber on actuation thereof, (h) means for yieldably urging said actuating means to an axially moved position out of engagement with said stem member when the valve head is in a seated position with said valve seat, whereby said actuating means is movable relative to said stem member prior to engagement therewith to move said valve head out of the seated position therefor, (i) said valve head, on release of said actuating means, being movable by said bias means to the seated position therefor prior to the movement of the actuating means to the axially moved position therefor, whereby any liquid at the discharge orifice of said passage means is withdrawn into said passage means by the retractive movement of said displacement member from said liquid discharge chamber, (j) said displacement member of the actuating means being tubular and mOunted in a concentrically spaced relation about said stem member and formed with an inwardly projected flange at the end thereof adjacent said liquid discharge chamber, (k) said bias means comprised of a coil spring mounted about said stem member and maintained in compression between said flange and the free end of the stem member, and (l) said coil spring, on release of the actuating means, and movement of the valve head to the seated position therefor, being compressible by the actuating means on movement thereof by the yieldable means to the axially moved position therefor.
