Abstract: A spray paint gun having a disposable cartridge inserted therein such that paint can flow through the cartridge in the spray gun without touching the spray gun. Since no part of the spray gun has paint touching it, there is no cleaning of the spray gun or its components. The cartridges can be easily inserted into the spray gun and easily removed such that different color paints can be used in the spray gun in quick succession without down time for cleaning. There is no use of solvents for cleaning, making the cartridge spray gun environmentally friendly. The disposable cartridges eliminate expensive time consuming cleaning. The cartridges can be breach loaded into the front portion of a spray gun and front portion containing the cartridge can quickly snapped into place and ready for use by a hinged connection to the rear portion or by other connection means.

Abstract: A connector part (3) for connecting a material supply device (10) to a spray gun (20) that includes a hollow cylindrical connection piece (5); a threaded wedge element (8) with a lower starting point (8a) and an upper end (8b) running around the outer circumference of connection piece (5) and serving to produce a threaded wedge connection to a counter-element (15) arranged on gun base (19) of spray gun (20); and a stop element (14) that forms a limit stop during the production of the threaded wedge connection. In order to prevent the counter-element on the spray gun from digging into the soft connection pipe made of plastic and removing plastic chips there, it is provided in the connector part according to the invention that stop element (14) is arranged at a distance in the circumferential direction from upper end (8b) of threaded wedge element (8), whereby a gap (11) is formed between stop element (14) and upper end (8b) of the threaded wedge element.

Abstract: The invention relates to a gravity flow reservoir for a paint spraying gun having a container and a cover, which can be placed thereon and which has a connecting part in order to place the gravity flow reservoir onto the paint spraying gun or onto an adapter. Prior art reservoirs require a separate pointed tool, which serves to make a vent hole, is often unavailable and can lead to operating errors. The aim of the invention is to provide a paint reservoir system that enables a simple, rapid and uncomplicated insertion of a vent hole into the container wall of the gravity flow reservoir while preventing shavings or plastic parts from entering the gravity flow reservoir. To this end, a delimited area is provided in the wall of the container and can be penetrated by the pointed tool in order to make a vent hole.

Abstract: The invention relates to a fluid reservoir for a paint spray gun, comprising a receptacle (1) and a lid that can be placed thereupon and is provided with a connecting element (3) in order to mount the fluid reservoir on the paint spray gun or an adapter. The receptacle (1) is provided with a ventilation hole (4) which can be sealed using a valve. In order to improve the tightness of the valve, said valve encompasses two valve seats for sealing the ventilation port (4), which are disposed one behind another in the direction of flow.

Abstract: The invention relates to a cleaning device for cleaning spray guns (S), particularly paint spray guns, having at least one cleaning nozzle (1) connected to a transport device (2) for cleaning fluid, and having a frictional cleaning device (3) for manually cleaning the spray guns or parts thereof Known cleaning devices of such a type can only insufficiently clean the paint spray channel. The object of providing a cleaning device by means of which parts of both the outer surface and the paint spray channel can be efficiently and environmentally soundly cleaned is achieved in that the cleaning nozzle (1) is disposed near and above the frictional cleaning device (3), so that cleaning fluid can be sprayed through the cleaning nozzle (1) into and/or on the spray gun (S), and the spray gun (S), and particularly the spray gun nozzle, can be simultaneously manually cleaned by friction using the frictional cleaning device (3).

Abstract: The invention relates to a flow reservoir for a paint spray gun with a bowl-shaped container (1), a cover (2) that can be set on the container (1), and an attachment part (3) for direct fixing of the flow reservoir to the paint spray gun. The flow reservoir is distinguished in that the attachment part (3) consists of a connector (5) formed directly on the cover (2) with a screw-wedge element (8) for direct quick-connect attachment of the flow reservoir to the 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: This invention is directed towards a paint spray gun having a gun body with a male thread and having an air nozzle ring with a female thread which can be screwed onto the male thread of the gun body. The diameter of the thread is between about 30 and about 40 mm. The thread of the invention is a trapezoid thread with a flank angle in the range of about +/?20% of 30°. The thread has a thread height within the range of about +/?20% of 1.1 mm, a root to crest clearance within the range of about +/?20% of 0.1 mm and a flank clearance within the range of about +/?20% of 0.15 mm. The effect of these modifications to a standard trapezoid thread with a flank angle of about 30° is that the thread is optimally adjusted to serve as a thread connecting the body of a paint spray gun and a nozzle ring.
