Abstract
A water vortex brush has a rotor connected with a brush member and rotatable by a water supplied to the rotor and exiting from the brush member. The water forms a vortex in the interior of the rotor, and the latter is provided with an opening communicating with outside air so that the outside air is aspirated by a negative pressure existing in the central area of the rotor and thereby nullifies the same. The brush has water discharge openings radially offset relative to the air aspirating opening. A rotatable and angularly bent handle, forming simultaneously a water supply conduit, is provided. The bristles of the brush member are selected so as to form a very thin layer at their periphery under the action of a centrifugal force during the operation of the brush.
Claims8
A water brush for cars and the like, comprising
- a housing including a generally circular portion;
- a water inlet opening for said housing and a water outlet opening for said housing;
- a rotor having an axis and mounted within said cylindrical portion of said housing eccentrically with respect to the same, said rotor including a base having a plurality of blades mounted thereon, said blades being so positioned that they are rotated by the force of water exiting said inlet opening, said blades extending substantially radially of said rotor but having a gap between the inner end of each blade and said axis of said rotor providing a means for dissipation of water under pressure thereinto;
- a brush member coupled with said rotor for rotation therewith, said eccentric mounting of said rotor providing a steadily increasing spacing between the outer ends of said blades of said rotor and the inner wall of the housing in the area of said generally cylindrical portion;
- and
- means for preventing the formation of a zone of negative pressure near said axis of said rotor, which zone would form otherwise in the absence of such means.
