DEVICE OF OUTFEED OF ENERGY OF FLUID MEDIUM Russian patent published in 2014 - IPC F03B9/00 F03B17/06 F03D5/02 

FIELD: engineering industry.

SUBSTANCE: invention is designed to convert the energy of the fluid medium. The device of outfeed of energy of fluid medium, immersed in the latter along the flow stream, comprises the working element in the form of an endless flexible chain covering the spaced apart from each other at least two toothed pulleys 2 or sprockets, or in the form of a belt 1 covering the spaced apart from each other at least two pulleys, parachutes 4 connected with the endless flexible chain or belt 1. At least one toothed pulley 2 or a sprocket of the endless flexible chain or belt of the pulley 1 is fixedly connected to the power takeoff shaft. The parachutes 4 are made with the ability to open under the pressure 5 of the medium flow and fold during the backward motion. The toothed pulleys 2 or the sprockets of the endless flexible chain or the pulleys of the belt 1 are positioned in the flow medium in the horizontal direction from each other with the ability to rotate around its axis, and each of them is made with the elements of engagement with the said chain or the said belt 1, in which the sleeves are mounted or fixedly attached to. In each sleeve the rod element is mounted with the ability to rotate about the vertically oriented axis, which is attached to a corresponding parachute 4.

EFFECT: invention is aimed at improving operating characteristics by providing a guaranteed engagement of the flexible element with the pulleys, and avoiding the braking of the flexible element and the parachutes when passing the pulleys or the sprockets.
