Abstract:
1. A vehicular brake comprising: a closed-circuit tunnel containing hydraulic liquid; a mechanism for moving said hydraulic liquid within said closed-circuit tunnel, together with a wheel of a vehicle; and at least one faucet within said closed-circuit tunnel, for reducing a cross-section area of said closed-circuit tunnel at least at one location, upon braking activity, wherein said mechanism comprises at least one vane disposed within said contained hydraulic liquid, for circulating said hydraulic liquid and for being rotated by said hydraulic liquid, said at least one vane being connected to said vehicle wheel; and wherein said closed-circuit tunnel comprises: an initial tunnel, in which motion of said at least one vane performs said circulation of said hydraulic liquid; and a bypass between the ends of said initial tunnel, in which said at least one faucet performs said reduction of said circulation, wherein said initial tunnel comprises a tunnel between: an external envelope of a disk rotating with said at least one vane; and an annular internal envelope of a stationary package of said vehicular brake, wherein the center of said disk is shifted from the center of said annular internal envelope, and wherein said at least one vane is adapted to substantially touch said annular internal envelope of said stationary package, and wherein said adaptation of said at least one vane to substantially touch said annular internal envelope of said stationary package, comprises: a piston slideable within a cylinder comprising each of said at least one vane; and a stationary leading track, for leading said piston to substantially touch said annular internal envelope of said stationary package, thereby braking said vehicle wheel without friction wear.
