    • A regulating valve comprising a housing having a cylindrical valve chamber, the valve chamber being provided with at least one inlet and at least two outlets, the inlet and the outlets being at least partially closeable as needed by a common valve body arranged in the valve chamber and rotatable around an axis, the valve body being operable by an actuator, the inlet and/or at least one of the outlets being surrounded by a sealing device on the side of the housing facing the valve body and the sealing device being able to be brought into sealing engagement with the valve body under elastic preload. The valve body is designed having the shape of the segment of a cylinder and is bounded on the peripheral side by two boundary surfaces which each have an edge on the side facing the housing, the edge overtravelling the inlet during its opening being designed as an efflux edge and having an elliptically shaped recess extending in axial direction. Configured in the valve body is a duct-shaped opening which extends between the boundary surfaces and penetrates them.

    • A bottom unit for the combustion chamber of a liquid-fueled rocket including a bottom plate held on a swivel bearing and having circumferentially distributed openings for the injection of the two fuel components as well as two separate groups of supply passages which are connected to these fuel injection openings. The swivel bearing consists of a rigid thrust plate and a rigid hanger plate which are held and joined together by an internally situated, first annular body of rubber elastic material and by a second annular body of rubber elastic material surrounding the first at a radial distance therefrom. The one group of supply passages is formed by the cavity surrounded by tthe first annular body and the other group of supply passages by the annular space between the first and the second annular body.
