Abstract
Abstract Means for locating a cylindrical part in an axial position in a hollow cylindrical part such as a propellant charge body and a jet nozzle body. A split spring washer grips in a circular groove in the cylindrical part, and in a circular groove in the hollow cylindrical part. A conical groove wall is provided on one of the two circular grooves. The connection of the two parts can be released in one direction, and can be loaded and locked in the other direction. For releasing the connection of both parts in the direction of loading and locking the cylindrical part is arranged in the hollow cylindrical part with radial play so that a relative tilting of both parts is impossible, and the spring washer upon gliding along on the conical groove wall is deformed and in the direction of loading and locking projects over the circular groove which contains the conical groove wall.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
200 words
Means for locating a cylindrical part in an axial position in a hollow cylindrical part particularly a propellant charge body in a jet nozzle, comprising a cylindrical part having an external circular groove, a hollow cylindrical part having an interior circular groove, a split spring washer for gripping in said external groove and in said interior groove, a conical groove wall on one of said two grooves whereby the connection means of said two parts can be released in one direction and can be loaded and locked in the other direction, said connection means for releasing the connection of both parts in the direction of loading and locking said cylindrical part being arranged in said hollow cylindrical part with radial play for a relative tilting of both said parts, the ratio of said radial play of said parts to the length of the overlap of both parts is at least as great as the ratio of the axial length of said conical groove wall to the inner radius of said hollow cylindrical part and said spring washer upon gliding along on said conical groove wall is deformed, and in the direction of loading and locking projects over said interior groove.
Claim 2
Dependent Claim
200 words
Means for locating a cylindrical part in an axial position in a hollow cylindrical part particularly a propellant charge body in a jet nozzle, comprising a cylindrical part having an external circular groove, a hollow cylindrical part having an interior circular groove, a split spring washer for gripping in said external groove and in said interior groove, a conical groove wall on one of said two grooves whereby the connection means of said two parts can be released in one direction and can be loaded and locked in the other direction, said connection means for releasing the connection of both parts in the direction of loading and locking said cylindrical part being arranged in said hollow cylindrical part with radial play for a relative tilting of both said parts, the ratio of said radial play of said parts to the length of the overlap of both parts is at least as great as the ratio of the axial length of said conical groove wall to the inner radius of said hollow cylindrical part and said spring washer upon gliding along on said conical groove wall is deformed, and in the direction of loading and locking projects over said interior groove.
Claim 3
Dependent Claim
41 words
Means as set forth in claim 1 wherein said cylindrical part has a collar and said hollow cylindrical part is kept at a distance in the locked position at the front surface of said collar by means of a rubber ring.
Claim 4
Dependent Claim
38 words
Means as set forth in claim 1 wherein the width of said external groove is greater than the wiDth of said spring washer and a flexible packing ring is located adjacent said spring washer in said external groove.
