Medium flow energy converting machine - has endless travelling supports mounted on a slewing frame at their forward-end pulleys which are closer together than the rear ones.

摘要

the supports travel round two end pulleys and have flat components (6) at intervals absorbing the energy from the flow and converting into rotary movement.There are two or more supports (19), mounted at their forward-end pulleys (4a) on a slewing frame (2). The distance between the pulleys is less than that between the rear-end ones, determined by flexible connecting components (7,8).The supports can consist of ropes running round pairs of forward-and rear-end pulleys,to which sails (6) are fixed at right angles to the travel direction and also to a frame (3). Alternatively they can be of flat strip, running round drums instead of pulleys. ADVANTAGE - Rapidly and automatic aligns to wind direction and simple protection against overloading.
