Abstract: The invention concerns a virtual painting system for simulating a paint application process and the resulting application of paint to a surface. The system includes a virtual paint applicator device, a position detector to detect the spatial position of the paint applicator device with respect to the surface to be painted, a data processing unit and a display device, wherein the position data of the paint applicator device are routed to the data processing unit, where they are converted into video data for rendering the virtual paint application visible, and which are further routed to the display device, in order to show a visual image of the virtual paint application process on the surface to be painted. This painting system makes possible a quick and, at the same time, realistic virtual representation of painting with a paint spray gun.

Abstract: A spray gun having a gun body; a nozzle assembly arranged on the gun body; a compressed air supply channel located in the gun body, controlled by a valve assembly, a regulator for adjusting the supply of the spray material, an actuating element for actuating the valve assembly) and the regulator and a pressure measuring device. A pressure measuring device, resistant to dirt, that contains a pressure sensor integrated into the gun body and is connected to the compressed air supply channel via a capillary (43) located within the gun body.

Abstract: A paint spraying gun with a gun body and a material supply device that are connected to one another by a screw-wedge connection. The screw-wedge connection includes a screw-wedge element that is arranged on the circumference of an essentially hollow-cylindrical connecting part of the material supply device, and a corresponding counter element on the gun body. The connection is inexpensively manufactured and easily handled. The screw-wedge element extends in an arc over more than half of the circumference of the connecting part with the ends of the screw-wedge element being peripherally spaced from one another. The counter element is an arcuate projection arranged on one side of and above a receiving bore of the gun body.

Abstract: Disclosed is a spray pistol having a pistol body, a nozzle system which is arranged on the pistol body, a compressed air supply channel which is arranged in the pistol body and with a valve device for control of the compressed air supply to the nozzle device, a regulating device for regulating the supply of the substance to be sprayed, an actuating element for actuating the valve system and the regulating device, a device for regulating the supply of compressed air to the nozzle device, a pressure measuring device for detecting and indicating the pressure in the compressed air supply channel, wherein the pressure-measuring device is integrated into the device used to regulate the compressed air supply.
