Title:
FLUID-DYNAMIC TRANSDUCER DEVICE FOR EXPLOITING THE KINETIC ENERGY OF LAND VEHICLES
Document Type and Number:
WIPO Patent Application WO2006120645
Kind Code:
A3
Abstract:
A fluid- dynamic transducer device for exploiting the kinetic energy of land vehicles comprises : a stationary support structure (2; 3, 4) in which a compression chamber with a variable cross-section (8) is defined between an inlet duct (9) and an outlet duct (11) for a fluid, a pumping element (16) being movably mounted inside said chamber; and a tread plate (20) movable with respect to the structure (2, 3,4) and coupled with the pumping element (16) . The support structure (2; 3, 4) has, defined inside it, a passage (14) separated from the compression chamber (8) , in a fluid- tight manner, by means of a resiliently deformable membrane (16) acting as a movable pumping element. A spherical piston (18) is mounted in this passage (14) , arranged between the membrane (16) and the tread plate (20) . The compression chamber (8) has a frustoconical surface against which, under the thrust of the spherical piston (18) , the membrane (16) bears at the end of a compression stroke .
