A dispensing device for cartridges having a trigger grip for operating a valve of the dispensing device, a connection for supplying a pressurized gas, a cartridge connector for connecting a cartridge, and a base body, in which at least one passage extends through such that pressurized gas can be guided to the cartridge connector. The cartridge connector comprises an opening towards the passage such that the content can be expelled from the cartridge upon application of the pressurized gas to the floor of a cartridge when the cartridge is arranged in the cartridge connector, and wherein the passage can be closed and opened through the operated valve. The valve has a valve body that is arranged in the base body in a rotatable manner, wherein a motion of the trigger grip leads to a rotation of the valve body in the base body. The passage is arranged in or on the valve body such that the passage is closed in a first position of the valve body and the passage in or on the valve body guides the pressurized gas to the cartridge connector in a second position of the valve body.

1. A dispensing device for cartridges comprising a trigger grip for operating a valve of the dispensing device, a gas connection for supplying a pressurized gas, a cartridge connector for connecting a cartridge, and a base body, in which a first passage extends through which the pressurized gas can be guided to the cartridge connector, whereby the cartridge connector comprises an opening towards the first passage such that the content can be expelled from the cartridge upon application of the pressurized gas to the floor of a cartridge that is arranged in the cartridge connector, and whereby the first passage can be closed and opened through operation of the valve, wherein the valve is a valve body that is arranged in the base body in a rotatable manner, whereby a motion of the trigger grip leads to a rotation of the valve body in the base body and the first passage is arranged in or on the valve body such that the first passage is closed in a first position of the valve body and the first passage in or on the valve body guides the pressurized gas to the cartridge connector in a second position of the valve body, whereina second passage is arranged in or on the valve body, which connects the cartridge connector to a first drain in a third position of the valve body such that any over-pressure on the cartridge connector can escape through the first drain in the third position of the valve body, whereina first drain channel is arranged in the base body in a manner such that it connects the second passage to the first drain in the third position of the valve body, and whereina third passage is arranged in or on the valve body, wherein the third passage comprises a branch and connects the cartridge connector and the pressurized gas to a second drain in the fourth position of the valve body such that an over-pressure in the dispensing device can escape through the second drain in the fourth position of the valve body, and further wherein a cross-sectional shape of the base body is the same cross-sectional shape across the entire length of the base body. 2. The dispensing device according to claim 1, wherein at least one front channel is arranged in the base body between the first passage and the cartridge connector and/or at least one rear channel is arranged between the first passage and the gas connection for supplying the pressurized gas. 3. The dispensing device according to claim 1, wherein a rear channel connecting with the first drain channel is arranged in the base body between the third passage and the gas connection for supplying the pressurized gas and/or the second drain channel is arranged in the base body in a manner such that is connects the branch of the third passage to the second drain in the fourth position of the valve body. 4. The dispensing device according to claim 1, wherein a pressure relief valve is arranged in at least one of the first and second drains. 5. The dispensing device according to claim 1, wherein the trigger grip is connected in fixed manner to an underside of the valve body such that the valve body is rotatable in the base body along with the trigger grip. 6. The dispensing device according to claim 1, wherein a position indicator is arranged on a top side of the valve body on which the position of the valve body in the base body is detectable via the position indicator. 7. The dispensing device according to claim 1, wherein a handle allowing the dispensing device to be held is arranged on an underside of the base body. 8. The dispensing device according to claim 2, wherein the valve body is rotationally-symmetrical at least over parts of the valve body and is mounted in rotatable manner in an opening in the base body that matches a shape of the valve body, wherein external walls of the valve body, except for openings of the first, second and third passages, end in a sealed manner against internal walls of the opening in the base body in any position of the valve body such that connections of the first, second and third passages to at least one channel in the base body are sealed. 9. The dispensing device according to claim 8, wherein a recess for a wedge is provided in the base body, whereby a wedge, that is inserted into the recess, presses the valve body into the opening in the base body. 10. The dispensing device according to claim 1, wherein, on a side of the base body facing away from the cartridge connector, a hollow space for a gas cartridge is provided, wherein the gas connection is arranged in the hollow space and comprises a mandrel for opening a gas cartridge, and fastening means for fastening a closure cap with fastening means are arranged on the base body, wherein the gas cartridge can be opened by the closure cap being fastened, wherein the closure cap comprises an additional locking means that engages a locking device in the hollow space, and further wherein the locking device is configured to position an inserted gas cartridge of appropriate size inside the hollow space. 11. The dispensing device according to claim 1, wherein the first, second and third passages extend essentially straight through an inside of the valve body and the first, second and third passages are offset with respect to each other by an angle of 10° to 80° about a rotation axis of the valve body. 12. The dispensing device according to claim 1, wherein, a second cartridge connector having a larger cross-section and a second opening is arranged at a front edge of the first cartridge connector, wherein the second cartridge connector is configured for connecting a second cartridge, and further wherein the second opening of the second cartridge connector is configured to allow a first cartridge to be connected to the first cartridge connector proceeding through the second opening of the second cartridge connector. 13. The dispensing device according to claim 12, wherein the first and second cartridge connectors are cylindrical hollow bodies, each having a closed side, whereby the closed side of the second cartridge connector comprises a second opening facing the at least one channel arranged in the base body and the closed side of the first cartridge connector comprises a first opening facing the at least one channel arranged in the base body. 14. The dispensing device according to claim 12, wherein fixation devices for fixing the first and second cartridges in place are arranged on insides of the first and second cartridge connectors. 15. The dispensing device according to claim 14, wherein the fixation devices are arranged in two concentric circles on the first and second cartridge connectors. 16.
