Abstract

Abstract An injector head for use in apparatus for injecting the fluid into an object in which there are one or more nozzle passages projecting outwardly with terminal portions adapted to engage the object being injected and in which there is valve means for preventing flow of fluid through the nozzle passage until the pressure of the fluid within the nozzle passage reaches a predetermined value at which time the valve means opens abruptly so as to cause a sudden release of the fluid. The injector head preferably has a plurality of nozzles and there is a valve in each nozzle. The valves preferably have their valving surfaces closely adjacent the terminal portions of the nozzle passages so that the change in pressure due to the opening of the valve is immediately transmitted to the fluid entering the object. The injector head is specifically designed for injection of an irregular object such as a turkey and the terminal portions of the nozzle passages are spaced varying distances from a vertical plane to conform with the surface of the object to be injected. The injector head is provided with a passage for circulation of injecting fluid so that where the injecting fluid is maintained at a temperature above the ambient temperature, this insures that the injector head will be maintained at a temperature close to the desired temperature for injecting the fluid and will not cause cooling of the injecting fluid at the time of injection. In one form of the invention, an annular passage is provided for circulating such fluid. In another form, the fluid is circulated through certain of the nozzle passages until such time as the pressure is increased to injecting pressure; at this time, the flow of circulating fluid is interrupted. In the case of an injector head for injecting a turkey, there are two rows of nozzle passages which diverge outwardly and downwardly, the nozzles projecting outwardly from a vertical plane progressively shorter distances proceeding from top to bottom. With this arrangement, the terminal portions of the nozzles fit closely against the opposite sides of the breast of a turkey or similar fowl.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 142 words
In apparatus for engaging a non-planar surface of an irregularly shaped object and injecting a fluid into the object: an injector head for engaging the object and injecting fluid therein, said injector head having an inlet opening adapted to be connected to a source of fluid under pressure, said injector head having a plurality of nozzle passages therein connected to said inlet opening and projecting outwardly varying distances from a plane substantially perpendicular to said passages so that the terminal portions of said nozzle passages approximately conform with the non-planar surface of the injected object engaged by the injector head, valve means for preventing flow of fluid through said nozzle passages, and means for maintaining said valve means closed until the pressure of the fluid reaches a predetermined value, said valve means being effective to open abruptly upon opening movement being initiated.
Claim 2
Dependent Claim 142 words
In apparatus for engaging a non-planar surface of an irregularly shaped object and injecting a fluid into the object: an injector head for engaging the object and injecting fluid therein, said injector head having an inlet opening adapted to be connected to a source of fluid under pressure, said injector head having a plurality of nozzle passages therein connected to said inlet opening and projecting outwardly varying distances from a plane substantially perpendicular to said passages so that the terminal portions of said nozzle passages approximately conform with the non-planar surface of the injected object engaged by the injector head, valve means for preventing flow of fluid through said nozzle passages, and means for maintaining said valve means closed until the pressure of the fluid reaches a predetermined value, said valve means being effective to open abruptly upon opening movement being initiated.
Claim 3
Dependent Claim 44 words
The apparatus of claim 1 in which the valve means consists of a plurality of valves, one for each of said nozzle passages, and in which each of said valves has a valving surface closely adjacent the terminal portion of the associated nozzle passage.
Claim 4
Dependent Claim 57 words
The apparatus of claim 1 in which the injector head has a passage connected to said inlet opening, and an outlet opening connected to said passage for circulating the fluid to be injected therethrough prior to the injection operation so that the injector head is maintained at a temperature approximately corresponding with the temperature of the fluid.
Claim 5
Dependent Claim 31 words
The apparatus of claim 3 in which the passage for circulation of fluid through said injector head is an annular passage located closely adjacent the inlet portion of the nozzle passage.
Claim 6
Dependent Claim 46 words
The apparatus of claim 3 in which the passage for circulating fluid to be injected prior to the injecting operation includes a plurality of such nozzle passages and in which valve means is provided for interrupting such circulaTion when the injection operation is to be initiated.
Claim 7
Dependent Claim 45 words
The apparatus of claim 5 in which said valve means for interrupting such circulation is pressure actuated and is responsive to the establishment of a pressure above a predetermined value to actuate said valve means to interrupt such circulation of fluid through the injector head.
Claim 8
Dependent Claim 24 words
The apparatus of claim 1 in which said nozzle passages are in the form of bores extending through a portion of said injector head.
Claim 9
Dependent Claim 23 words
The apparatus of claim 1 in which said nozzle passages are formed by nozzle members secured to and projecting from the injector head.
Claim 10
Dependent Claim 129 words
In apparatus for injecting a fluid additive into the flesh of a fowl to improve the eating qualitites thereof: an injector head for engaging the breast of the fowl to inject fluid therein; said injector head having two rows of nozzle passages diverging downwardly away from each other, said nozzle passages of each row projecting outwardly progressively shorter distances, proceeding from one end of the row to the other, from a plane, substantially perpendicular to said passages so that the terminal portions of said passages approximately conform with the surface of the breast of a typical fowl; and said injector head having an inlet opening adapted to be connected to a source of fluid additive under high pressure and said inlet opening communicating with each of said nozzle passages.
Claim 11
Dependent Claim 129 words
In apparatus for injecting a fluid additive into the flesh of a fowl to improve the eating qualitites thereof: an injector head for engaging the breast of the fowl to inject fluid therein; said injector head having two rows of nozzle passages diverging downwardly away from each other, said nozzle passages of each row projecting outwardly progressively shorter distances, proceeding from one end of the row to the other, from a plane, substantially perpendicular to said passages so that the terminal portions of said passages approximately conform with the surface of the breast of a typical fowl; and said injector head having an inlet opening adapted to be connected to a source of fluid additive under high pressure and said inlet opening communicating with each of said nozzle passages.
Claim 12
Dependent Claim 53 words
The apparatus of claim 9 in which the orifice through the terminal portion of the uppermost of said nozzle passages is greater than that through the lowermost of said nozzle passages so that a greater amount of fluid is injected in the portion of the breast of the fowl adjacent the upper nozzle.
Claim 13
Dependent Claim 52 words
The apparatus of claim 9 in which a valve is located in each of said nozzle passages with the valving surface of the valve closely adjacent the terminal portion of the nozzle passage so that the change in pressure upon the valve opening is immediately transferred to the fluid entering the object.
