Abstract:
1. A vehicle light cleaning device comprising an elongate housing formed with an inlet port connectable to a source of pressurized rinsing liquid, a rinsing head fitted with at least one jet nozzle and mounted at a distal end of a telescopically retractable hollow tube, said tube, being normally retracted; a liquid flow path extending between said rinsing head and an inside space of the housing; a normally closed sealing assembly adapted to open the liquid flow path only responsive to full projection of the tube from the housing; the tube, is coaxially received within a sleeve telescopically projectable from the housing and formed at a proximal end thereof with the liquid sealing assembly; said liquid sealing assembly comprising an aperture formed at a proximal end of the sleeve and sealable by a radial valve radially displaceable between a normally closed position, and an open position where it radially disengages from the aperture responsive to full projection of the sleeve and the associated tube, to facilitate liquid flow from the housing, into the tube, wherein the radial valve is retained in the closed position by a retention member displaceable over an inclined surface between a sealed position where it is substantially flush with an external surface of the sleeve, and an open position where it radially projects; and further the sealing assembly comprises a stopper member extending at a distal end of the housing, whereby upon full projection of the tube said stopper member arrests axial displacement of the sleeve resulting in displacement of the radial valve along said inclined surface so as to radially displace into the open position.
