The invention relates to a spray pistol comprising a pistol body (1); a nozzle system (9) which is ranged on the pistol body (1); a compressed air supply channel (22, 23) which is arranged in the pistol body (1) and which comprises a valve system (17) for controlling the supply of compressed air to the nozzle system (9); a regulating device (6, 13) for regulating the supply of the substance to be sprayed; an actuating element (12) for actuating the valve system (17) and the regulating device (6, 13); a device (31, 33, 37) for regulating the supply of compressed air to the nozzle system (9); and a pressure-measuring device (35, 38, 39) for detecting and indicating the pressure in the compressed air supply channel (22, 23). The aim of the invention is to create a compact and handy spray pistol comprising a pressure-measuring device which is easy to monitor when spraying. In order to achieve this, the pressure-measuring device (35, 38, 39) is integrated into the device (31, 33, 37) used to regulate the compressed air supply.
1 (amended). A spray pistol, comprising:
2 (amended). Spray pistol according to claim 1, wherein the device for regulating the supply of compressed air contains a casing adjustable by means of a regulating element with a transverse drilled hole for adjusting of a transit cross section of the compressed air supply channel.
3 (amended). Spray pistol according to claim 2, wherein the pressure measuring device contains a pressure sensor arranged in the regulating device.
4 (amended). Spray pistol according to claim 2 wherein the pressure measuring device contains an indicating device arranged in the regulating device.
5 (amended). Spray pistol according to claim 3 wherein the regulating device has a receiving part that rotates with the casing and has a housing joined to said receiving part.
6 (amended). Spray pistol according to claim 5, wherein the pressure sensor is located in the receiving part and the indicating device is located in the housing.
7 (amended). Spray pistol according to claim 6, wherein the indicator device is arranged at one back side of the housing.
8 (amended). Spray pistol according to one of claims 3 wherein the pressure sensor is in connection with the compressed air supply channel by means of a capillary.
9 (amended). Spray pistol according to one of claims 2 wherein the regulating device is designed as an adjusting knob.
10 (amended). Spray pistol according to one of claims 4 wherein the indicator device is designed as a digital display.
