Abstract

See full text

A powder jet device (10) for dispensing a dental material comprises a nozzle head (12) comprising a discharge nozzle. The powder jet device (10) further comprises a housing (14) comprising a valve portion (28), which is connected to the nozzle head (12) and is adapted to receive a valve member (16), and a chamber portion (30) comprising at least a first chamber (32) for storing a powder material. The chamber portion (30) comprises a proximal end (34) located adjacent the valve portion (28), a distal end (36) located away from the valve portion (28) and a fluid channel (38) extending from the distal end (36) substantially to the proximal end (34) into the chamber. The powder jet device (10) further comprises a valve member (16) disposed within the valve portion (28). The valve member (16) comprises a fluid supply passage (54) and is movable between a first position, in which a first fluid path (64) for delivery of a fluid from the fluid supply passage (54) into the chamber via the fluid channel (38) so as to create a dispersion from the powder material and a second fluid path (66) for delivery of the dispersion to the discharge nozzle are open, and a second position, in which at least the first fluid path (64) is closed.
