Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
139 words
Jet propulsion for water and aircraft as well as circulation pumps, having the characteristic that the fluid entering through a propulsion pipe (11) is accelerated against the intended direction of propulsion by at least one propulsion element like a rotor having the shape of an auger (17); having also the characteristic that the outer edge of the auger (17) is firmly attached to the inner casing of the propulsion jet (11), and that the inner edge of the augers limits a central opening parallel to the axis, the auger and the propulsion pipe (11) rotating together, whereat the propulsion pipe (11) is driven at its outer casing, having the characteristic that on one of the outer casing sections kept free from the propulsion pipe bearing (12) at least one additional propulsion element like a screw propeller (18) is fitted.
Claim 2
Dependent Claim
24 words
Jet propulsion according to Claim 1, having the characteristic that the screw propeller (18) is arranged at the outlet of the propulsion pipe (11).
Claim 3
Dependent Claim
26 words
Jet propulsion according to Claim 1, having the characteristic that the propulsion pipe (11) rests in a sleeve pipe or sleeve casing (12) or something similar.
Claim 4
Dependent Claim
28 words
Jet propulsion according to Claim 1, having the characteristic that the propulsion pipe (11) from the intake (11b) to the outlet (11a), or in partial sections, is converging.
Claim 5
Dependent Claim
34 words
Jet propulsion according to Claim 1, having the characteristic that the inner casing of the propulsion pipe (11) at the outlet (11a) and possibly also at the inlet (11b) is free from propulsion elements.
Claim 6
Dependent Claim
26 words
Jet propulsion according to Claim 1, having the characteristic that the outlet (11a) of the propulsion pipe (11) has the shape of a propelling nozzle (32).
Claim 7
Dependent Claim
25 words
Jet propulsion according to Claim 1, having the characteristic that the thickness of the auger material (17) increases in the direction of the outlet (11a).
Claim 8
Dependent Claim
31 words
Jet propulsion according to Claim 1, having the characteristic that the sleeve pipe casing (12) has openings (12a) in the vicinity of the bearings (13) allowing the entering of the water.
Claim 9
Dependent Claim
27 words
Jet propulsion according to Claim 1, having the characteristic that the sleeve pipe casing (12) is fastened to a column (2) or an extension arm casing (14).
Claim 10
Dependent Claim
24 words
Jet propulsion according to Claim 1, having the characteristic that the sleeve pipe casing (12) forms one piece with the extension arm casing (14).
Claim 11
Dependent Claim
40 words
Jet propulsion according to at least one of the foregoing claims, having the characteristic that the propulsion pipe (11) between the bearings (13) is designed as a propulsion element like, for instance, crown gear (16), armature (21), or scoops (28).
Claim 12
Dependent Claim
68 words
Jet propulsion according to at least one of the foregoing claims, having the characteristic that the drive link (16, 21, 18) works together with a corresponding drive element like toothed belts (15), drive pinion (19), magnetic winding (23) or turbine (26) including nozzles (27) with feed and return lines (24, 25), the sleeve pipe casing (12) and/or the extension arm casing (14) being built into the drive unit.
Claim 13
Dependent Claim
15 words
Pipe system with circulation pump shaped according to at least one of the aforementioned claims.
Claim 14
Dependent Claim
14 words
Jet propelled boat according to one or more of the Claims 1 to 12.
