Abstract
The present invention relates to a spray gun for the expulsion of a fluid, with at least one cylinder (1) in which a piston (2) is mounted movably, the cylinder (1) having formed in it a fluid chamber (3), the volume of which can be varied by means of a movement of the piston (2) and in which at least one first cylinder orifice (5) is formed, and a spray orifice which is connected to the first cylinder orifice (5) of the cylinder (1) via a connecting line (20), so that a fluid, which is received by the fluid chamber (3) and is pressed out through the first cylinder orifice (5) by the pressure exerted by the piston (2), arrives via the connecting line (20) at the spray orifice and is expelled there. The spray gun according to the invention is distinguished by the fact that a fluid valve (21) is arranged in the connecting line (20), and, in the cylinder (1) a sensor (29) is provided, by means of which a defined position of the piston (2), in which fluid is still located in the fluid chamber (3) during the expulsion operation, can be detected, and by means of which the fluid valve (21) can be actuated, the fluid valve (21) being closed by means of the sensor (29) when the defined position of the piston (2) has been detected. The invention relates, furthermore, to the use of such a spray gun for the expulsion of plant protectants.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
