Abstract: Arrangement for washing transparent parts of vehicles, particularly windshields and lightlamp lens shields of motor vehicles. The arrangement includes a solid liquid conducting member and a bore-like liquid supplying channel extending therethrough between an inlet port and an outlet port. A liquid conduit communicating with a liquid container has a terminal portion distant from the container and provided with a connecting piece press-fit or with prestress inserted in the inlet port. A nozzle body is associated with the outlet port and has a discharge aperture aimed at the transparent part to be washed. A selectively actuable liquid releasing means is operable to release liquid to travel from the container under pressure at the driver's command to the nozzle body.
