Water spray for cleaning a vehicle windscreen

摘要

The water spray for a vehicle windscreen cleaning system has a fluid distribution wheel (26) rotating in a fixed housing (16) mounted on a fixed rotary axis (27), to work with a calibrated opening (20). The wheel has a number of spray channels (30) with an entry (31) at the feed side, and is set to work in a cycle with the calibrated opening (20). The spray channel (30) has a curvature from the inlet (31) away from the rotary axis (27), so that the distribution wheel (26) is rotated automatically by the fluid flow at a higher speed.
