A DEVICE IN FLUID PRESSURE GENERATORS

摘要

A device in fluid pressure generators comprising an annular casing (4) which is peripherally mounted and driven in a through-flow channel (1). The inner face of said annular casing forms part of the wall of the through-flow channel. The annular casing (4) is provided with a number of propeller blades (2) which extended radially inwards into the through-flow channel (1) and which are rotationally mounted on their individual pin shafts (3) by means of which propeller blades the magnitude of the thrust may be altered in a continuous manner and the direction of operation of said thrust in the through-flow channel be reset.
