Cartridge system having a device for synchronising two fluid flows

A cartridge system, for mixing and applying two fluids or flowable pastes, comprising two cartridges (10) and a dispensing opening (80), whereby the two cartridges (10) are bordered through cartridge walls and through a cartridge head (20, 120), whereby at least one cartridge opening (30, 130, 230), each for expelling the cartridge contents from both cartridges (10), is provided in the cartridge head, wherein a device (40, 140, 240), for regulating fluid flows from the cartridges (10), is arranged on the cartridge head (20, 120) and comprises at least two wings (60, 160, 260) and at least two openings (50, 150, 250) which overlap, at least partly, with at least two cartridge openings (30, 130, 230), whereby the device (40, 140, 240) is arranged on the cartridge head (20, 120) to be rotatable or shiftable, whereby the at least two openings (50, 150, 250) have arranged thereon at least one wing (60, 160, 260) each projecting, at least partly, over the openings (50, 150, 250), such that a fluid flow through the at least two openings (50, 150, 250) effects, via the wings (60, 160, 260), a force as a result of the fluid flow that acts on the device (40, 140, 240) and is parallel to an axis of the at least two openings (50, 150, 250) leading to the device (40, 140, 240) being rotated or shifted with respect to the cartridge head (20, 120) upon which surface area of the cartridge openings (30, 130, 230) overlapping with the device (40, 140, 240) changes, and in that the cartridge head (20, 120) has a housing (70) comprising the dispensing opening (80) arranged on the cartridge head, in which the device (40, 140, 240) is arranged to be rotatable or shiftable.
