Dispensing device for cartridges

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, wherein
• a 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, wherein
• a 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 wherein
• a 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.
