  • Turbo-engine having a variable pitch propeller
    Patent number: 5489189
    Abstract: The invention relates to turbo-engine having a variable-pitch propeller. An adjustment spindle is disposed inside the shaft that carries the variable-pitch propeller. The adjustment spindle is connected to a step-down transmission, which is affixed in the area of the face side of the motor that drives the variable-pitch propeller or at a driven generator, and which interacts with an adjustment motor.

  • Propeller shaped agitator
    Patent number: 5385448
    Abstract: A multibladed propeller shaped agitator includes a plurality of impellers having made blades, blade roots and hub segments made of plastic material. A metallic hub element is inlaid only in the hub segment. The impellers are connected to the hub segment such that stress peaks, imparted from a driving force, in the region of the blades, blade roots and hub segments are substantially prevented.

  • Elbow casing for fluid flow machines
    Patent number: 4828457
    Abstract: A casing which admits the fluid medium into the range of the impeller or first impeller in a fluid flow machine, particularly in a centrifugal pump, is made of several sections which have abutting surfaces. At least one such surface has a recess forming part of a fluid flow passage, and the recess is machined into the respective surface by a material removing tool. This simplifies the making of the casing and enables the latter to optimally conform to the conditions of flow between the supply conduit and the impeller or first impeller of the machine to thus reduce noise and stray movements and enhance the efficiency of the machine.

  • Barrel housing for centrifugal fluid machines
    Patent number: 4536128
    Abstract: The barrel housing of a multistage centrifugal pump has an elongated cylindrical main section and a discrete annular section which is inserted into one end portion and defines an annular shoulder facing the other end portion of the main section. The shoulder is engaged by the inner casing of the pump. The annular section can constitute a prefabricated component or is formed by cladding. The inlet opening of the housing is provided only in the one end portion of the main section, only in a portion of the annular section which extends outwardly beyond the one end portion of the main section, or is a composite opening having a first part in the one end portion of the main section and a registering second part in the annular section. The outlet opening for compressed fluid is provided in the other end portion of the main section.
