<p>The washer, mounted e.g. inside a motor vehicle bumper, has a nozzle with a carrier on the end of a sliding rod (5) forming part of a telescopic cylinder (3) with a body (4). The cylinder has a return spring to retract the rod, and a locking ring (22) to retain the rod in an intermediate position. The locking ring position can be adjusted by a system of inner notches that can be engaged with different ribs (24) on the rod surface by rotating it in a gap (24c) in the ribs.</p> |
