<p>The adjustable nozzle system for withdrawal spraying device includes a nose cartridge and an integral nozzle cover, which can be screwed to the cartridge. The nozzle cover has a dispensing opening which is located on its front part and a flanged sleeve which starts from its front wall. The flanged sleeve of the nozzle cover is screwed from its internal rear part and the internally versatile or step-like surface is looking to the front compared to the winding for creating circular surfaces of smaller diameter in two locations looking backwards along the inner winding inside the flanged sleeve of the nozzle cover. The nozzle cover is screwed (positioned with the help of windings) onto a part of the cartridge featuring an external winding and is positioned optional in the sense of unwinding between three optional positions so that the position of the internal wall surface and the circular surfaces of the flanged sleeve of the nozzle cover enables selective cooperation with the front part and the circular periphery of the cartridge front circle which includes two circular grooves inside its circular periphery by which a position can be selected where the liquid is sprayed from the dispensing opening and a position where the liquid is dispensed in a jet from the dispensing opening.</p> |
