Abstract
Abstract A deviating device, especially for particularly hot exhaust gas jets of air vehicle driving mechanisms, which comprises a plurality of metal strips or plates which are fixedly arranged on the outlet of the driving mechanism and which extend in the direction of the axis of the driving mechanism beyond the outlet of the driving mechanism. The metal strips or plates are for purposes of a jet deviation elastically deformable through the intervention of an adjusting device which is operatively connected to that end of the metal strips or plates which is remote from the outlet of the driving mechanism.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
110 words
A deviating device for exhaust gas jets, especially for particularly hot exhaust gas jets, or an air vehicle driving mechanism having gas jet outlet means, which includes: a frame surrounding at least part of said jet outlet means, a plural of elastically deformable and flexible plate means arranged parallel to each other having portions at one end thereof fixedly connected to said frame and having their opposite end protruding in outward direction beyond said gas jet outlet means, and adjusting means operatively connected to said protruding ends of said plate means and operable to deflect said plate means to thereby deflect the gas jets leading said gas jet outlet means.
Claim 2
Dependent Claim
110 words
A deviating device for exhaust gas jets, especially for particularly hot exhaust gas jets, or an air vehicle driving mechanism having gas jet outlet means, which includes: a frame surrounding at least part of said jet outlet means, a plural of elastically deformable and flexible plate means arranged parallel to each other having portions at one end thereof fixedly connected to said frame and having their opposite end protruding in outward direction beyond said gas jet outlet means, and adjusting means operatively connected to said protruding ends of said plate means and operable to deflect said plate means to thereby deflect the gas jets leading said gas jet outlet means.
Claim 3
Dependent Claim
156 words
A deviating device for exhaust gas jets, especially for particularly hot exhaust gas jets, or an air vehicle driving mechanism having gas jet outlet means, which includes: a frame surrounding at least part of said jet outlet means, a plurality of elastically deformable and flexible plate means having portions at one end thereof fixedly connected to said frame and having their opposite end protruding in outward direction beyond said gas jet outlet means, adjusting means operatively connected to said protruding ends of said plate means and operable to deflect said plate means to thereby deflect the gas jets leading said gas jet outlet means, said adjusting means including an actuating bar connected to all of said plate means, lever means connected to said bar, and actuating means operatively connected to said lever means for selectively shifting the same in either direction to thereby move said bar in a corresponding direction for deflecting said plate means correspondingly.
Claim 4
Dependent Claim
156 words
A deviating device for exhaust gas jets, especially for particularly hot exhaust gas jets, or an air vehicle driving mechanism having gas jet outlet means, which includes: a frame surrounding at least part of said jet outlet means, a plurality of elastically deformable and flexible plate means having portions at one end thereof fixedly connected to said frame and having their opposite end protruding in outward direction beyond said gas jet outlet means, adjusting means operatively connected to said protruding ends of said plate means and operable to deflect said plate means to thereby deflect the gas jets leading said gas jet outlet means, said adjusting means including an actuating bar connected to all of said plate means, lever means connected to said bar, and actuating means operatively connected to said lever means for selectively shifting the same in either direction to thereby move said bar in a corresponding direction for deflecting said plate means correspondingly.
Claim 5
Dependent Claim
38 words
A device according to claim 2, in which said bar extends through said plate means and adjacent said respective plate means is provided with a pair of pins arranged on opposite sides of the respective adjacent plate means.
