Definitions
- the invention relates in particular to a double discharge cartridge with a mixing device for polyurethane systems according to the preamble of claim 1.
- the invention is therefore based on the object of a double discharge cartridge for To create two-component systems that block the outlet openings and prevent the components from flowing back into the cartridge, so that the cartridge can be used again even after work breaks.
- the check valve is moved by a movable one arranged at the outlet opening Valve flap formed, the outlet opening in the unloaded state covers. It is expedient to arrange the valve flaps on a valve body on, the nozzle of the cartridge can be placed.
- the valve flaps and the valve body can be made in one piece as an injection molded part from a highly elastic plastic his. In a further embodiment of the invention, however, it is also possible the valve flaps from a resilient material as separate parts produce the inserted in corresponding pockets on the valve body are.
- the valve body 1 shown in Figure 1 is in one piece as an injection molded part made of plastic manufactured.
- the two are semicircular in cross section and through the slot 2 separate plug-on parts 3, 4 are provided with outlet channels 5, 6, which correspond to the corresponding Outlet openings 7, 8 of the cartridge 9 after placing the Align valve body 1.
- the two plug-on parts 3, 4 are connected to one another via the web 10 connected. Both sides of the outlet channels 5, 6 are angular on the valve body 1 Injection molded valve flaps 11, 12. If the valve body 1 on the nozzle 14 of the Cartridge 9 placed, the valve flaps 11, 12 are erected so that they Cover outlet channels 5, 6.
- the valve flaps are 11, 12 integrally molded on the valve body 1.
- valve body 1 To accommodate the legs 13 of the two valve flaps is a corresponding one in the outer surface of the valve body 1 Recess 15 introduced. At the top of the valve body 1 is a circumferential collar 16 is arranged to limit the plug-in, which after plugging sits on the nozzle edge of the cartridge 9.
- valve flaps 11, 12 When the components are pressed out of the two chambers 17, 18, a Pressure on the valve flaps 11, 12, which opens them (shown in dashed lines). Is the Squeezing process ended, a pressure relief occurs, so that the Valves 11, 12 close automatically due to their restoring force.
- a pressure relief occurs, so that the Valves 11, 12 close automatically due to their restoring force.
