Abstract
Abstract A pressure responsive fluid nozzle wherein an expellable plug is disposed in the outlet of a body member having an inlet adapted for connection to a source of fluid under pressure. The plug is connected relative to the body member by means of a connector which is placed under tension in response to the fluid pressure in the body member. Upon the fluid pressure attaining a predetermined magnitude, the connector is adapted to break to release the plug from the outlet and permit the fluid to be discharged from the nozzle.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
89 words
A fluid nozzle comprising a body member having an inlet for a source of fluid under pressure, an outlet for discharging said fluid, plug means disposed in said outlet, means for connecting said plug means relative to said body member, and means responsive to a predetermined fluid pressure in said body member for placing said connecting means in tension, said connecting means being adapted to break after a predetermined tension and release said plug means from said body member to permit expulsion of said plug means from said outlet.
Claim 2
Dependent Claim
89 words
A fluid nozzle comprising a body member having an inlet for a source of fluid under pressure, an outlet for discharging said fluid, plug means disposed in said outlet, means for connecting said plug means relative to said body member, and means responsive to a predetermined fluid pressure in said body member for placing said connecting means in tension, said connecting means being adapted to break after a predetermined tension and release said plug means from said body member to permit expulsion of said plug means from said outlet.
Claim 3
Dependent Claim
28 words
The nozzle of claim 1 wherein said connecting means is in the form of a thread secured at each end to said plug means and said body member.
Claim 4
Dependent Claim
28 words
The nozzle of claim 1 wherein said body member includes an internal vane to impart a swirling motion to said fluid as it passes through said body portion.
Claim 5
Dependent Claim
18 words
The nozzle of claim 3 wherein said connecting means is attached to said plug means and said vane.
Claim 6
Dependent Claim
21 words
The nozzle of claim 1 wherein said fluid pressure acts on said plug means to place said connecting means in stress.
Claim 7
Dependent Claim
35 words
The nozzle of claim 1 further comprising latching means for retaining said plug means in said outlet, and means responsive to a predetermined temperature in the vicinity of said nozzle for releasing said latching means.
Claim 8
Dependent Claim
79 words
A fluid nozzle comprising a body member having an inlet for a source of fluid under pressure, an outlet for discharging said fluid, plug means disposed in said outlet, means normally connecting said plug means relative to said body member in a manner so that a predetermined fluid pressure in said body member acting on said plug means breaks the connection between said plug means and said body member to permit expulsion of said plug means from said outlet.
Claim 9
Dependent Claim
79 words
A fluid nozzle comprising a body member having an inlet for a source of fluid under pressure, an outlet for discharging said fluid, plug means disposed in said outlet, means normally connecting said plug means relative to said body member in a manner so that a predetermined fluid pressure in said body member acting on said plug means breaks the connection between said plug means and said body member to permit expulsion of said plug means from said outlet.
Claim 10
Dependent Claim
28 words
The nozzle of claim 1 wherein said connecting means is in the form of a thread secured at each end to said plug means and said body member.
Claim 11
Dependent Claim
20 words
The nozzle of claim 8 wherein said fluid pressure acts on said plug means to place said thread in tension.
Claim 12
Dependent Claim
35 words
The nozzle of claim 7 further comprising latching means for retaining said plug means in said outlet, and means responsive to a predetermined temperature in the vicinity of said nozzle for releasing said latching means.
