Adhered surface particle removal device for cleaning dry surfaces has wetting device for wiper element provided with turbulence element in fluid feed channel

摘要

The device removes adhered particles from a dry surface using a wiper element displaced relative to the surface, provided with a wetting device (4) having a feed channel (6) leading to a spray opening (5). The feed channel contains an element (8) of lesser cross-section, moved irregularly by the flow along the channel, for causing turbulence and preventing deposits in the feed channel..
