Abstract:
1. A fluid device ( 1 ; 20 ; 40 ; 50 ; 60 ; 70 ; 80 ; 90 ; 90 ′; 90 ″) for recovery of the kinetic energy of vehicles, comprising an intake pipe ( 13 ), a delivery pipe ( 15 ), and a pumping unit ( 7 ; 22 ; 104 ), which is connected to said intake pipe ( 13 ) and to said delivery pipe ( 15 ) for sending fluid under pressure from said intake pipe ( 13 ) to said delivery pipe ( 15 ), and one elastically deformable actuating element ( 22 ; 76 ), which is suitable for being set along a road or railway course ( 3 ; 75 ) of a road or railway infrastructure ( 3 a , 71 ) for land vehicles, cooperates with said pumping unit ( 7 ; 22 ; 104 ) and can move between an unloaded position of and a loaded position, in which said actuating element ( 22 ; 76 ) is adapted to be surmounted by a vehicle travelling along said road course ( 3 ), said actuating element ( 22 ; 76 ) having a contact surface ( 26 ) suitable for being in contact with said vehicles, said fluid device being characterized in that said pumping unit ( 7 ; 22 ; 104 ) comprises rigid walls ( 101 , 107 ) and a membrane ( 108 ) connected in a fluid tight manner to said rigid walls ( 101 , 107 ) and cooperating with said actuating element ( 22 ; 76 ) to pump said fluid into said delivery pipe ( 15 ).
