Abstract
A fluid dispensing nozzle has a first venturi created between a seat ring and a movable, resiliently biased poppet valve. The resistance of the movable poppet valve is decreased as the flow rate increases by a second venturi effect, which reduces the pressure in a chamber formed within the movable poppet valve.
Claims2
A body having a valve to control flow therethrough a spout to dispense fluid from said body, means to releasably connect said spout to said body, means cooperating with one end of said spout to prevent rotation of said spout and maintain alignment of said spout relative to said body, said cooperating means including means on said spout and said body cooperating with each other, said cooperating means on said spout including means fixedly supported on said spout in a substantially fixed position relative thereto, said cooperating means on said body having receiving means and said supported means including means disposed in said receiving means of said body.
A fluid dispensing nozzle, comprising:
- (a) a body having inlet and outlet openings with a flow passage therebetween;
- (b) a valve in the body movable between open and closed positions to selectively establish fluid communication between the inlet and outlet openings;
- (c) a retainer fitted to the body proximal to the outlet opening and adapted to receive a discharge spout;
- (d) a discharge spout releasably secured to the retainer for discharging fluid flowing through the body;
- and
- (e) means associated with the discharge spout for positively engaging the body and preventing rotation and maintaining alignment of the spout relative to the body.
