    摘要: 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.

    摘要: The invention relates to a method for ejecting a pesticide by means of a fluid chamber 3, which communicates via an electrically controlled fluid valve 48 having a spout 22. The method comprises the following steps: determining a pressure and a duration of a time interval for ejecting the pesticide, filling the pesticide into the fluid chamber 3, applying a defined pressure on the pesticide in the fluid chamber 3 and opening the fluid valve 48 by means of an electric control signal for a specific, previously determined time interval and closing the fluid valve 48 after the time interval has expired, so that a defined volume or a defined weight of the pesticide is ejected by the spout 22. The invention further relates to a spray gun for carrying out the method and to the use of said spray gun for ejecting liquid, in particular gel-like, pesticide.
