Patent ID: 8763932

Claim:
Device for atomization of a pressurized liquid, with a container for the liquid, with a valve and with a spray head downstream of the valve, wherein the valve has a cylindrical section having a central axis, the cylindrical section projecting from an inner side of the spray head in an axial direction along said central axis and oriented toward the container; wherein the liquid can be atomized through a nozzle of the spray head with the valve opened, the device forming a throttle for the liquid, which is flowing through, upstream of the nozzle, the throttle comprising a slot-shaped, radially open throttling groove extending in said axial direction, the throttling groove having an longitudinally extending open side which is covered by a connector piece of the valve which extends towards the spray head in said axial direction, the connector piece being in sliding contact with the periphery of the cylindrical section except at the open side of said throttling groove, the portion of the length of the groove that is covered by the connector piece forming a flow conduit having an effective length which determines the flow resistance of the throttle, said effective length being settable by positioning of the cylindrical section relative to the connector piece.
