TELESCOPIC LIQUID-EJECTION DEVICE FOR VEHICLE WINDOW-WASHING SYSTEMS

摘要

It comprises a hollow outer section (1) and a hollow inner rod (2) connected at one end to a nozzle (3) and sliding inside said hollow outer section (1) against the force of a spring (5) under pressure exerted by said liquid. Selective means for communication which enable the liquid to move to the nozzle (3), when said hollow inner rod (2) has reached a predetermined extended position. One far end of the nozzle (3) has a flattened configuration (6) and the nozzle (3) and part of the hollow inner rod (2) can protrude from an outer surface (9) of the vehicle when the hollow inner rod (2) is in an extended position, whereas when it is in a retracted position, said flattened configuration (6) lies flush of under this surface (9).
