Abstract: A telescopic liquid-ejection device for vehicle window-washing systems is provided. It comprises a hollow outer section and a hollow inner rod connected at one end to a nozzle and sliding inside said hollow outer section against the force of a spring under pressure exerted by said liquid. Selective means for communication which enables the liquid to move to the nozzle, when said hollow inner rod has reached a predetermined extended position. One far end of the nozzle has a flattened configuration and the nozzle and part of the hollow inner rod can protrude from an outer surface of the vehicle when the hollow inner rod is in an extended position, whereas when it is in a retracted position, said flattened configuration lies flush of under this surface.

Abstract: The device is comprised of a jet body (2) and a body for a fan shaped squirt (3) which can be mutually coupled. The squirt body (3) has a squirting orifice (9) which comprises four consecutively connected portions, of which, in the washer fluid flow direction, the first portion (10) is conical and in decreasing section; the second section portion (11) forms a spherical cap in decreasing section; the third portion (12) is in rectangular cross-section and in increasing section; and the fourth portion (15) is in rectangular cross-section in decreasing section in said flow direction and configures a convex outlet edge (16), which is surrounded by an outer lateral squirting groove.
