ABSTRACT:
The present invention relates to a nozzle assembly adapted for use with an injector device having an energy generating source and a chamber adapted for holding a fluid and having first and second end portions with an orifice defined at the first end portion for passage of the fluid and being open at the second end portion. The device includes a first driving member movably positioned in the chamber; a second driving member movably positioned in the chamber and spaced apart from the first driving member according to a predetermined travel distance and including an end portion operative for expelling fluid out of or drawing fluid into the chamber via the orifice; and a spacing member disposed between the first and second driving members for maintaining said predetermined travel distance during displacement of the first and second driving members before the energy generating source is activated.
