Abstract:
1. A cartridge insert ( 1 ) for insertion in a fluid line, comprising a cartridge housing ( 2 ) having at least one backflow inhibitor ( 3 ) therein and at least one flow regulator ( 4 ) located downstream in a flow direction therefrom, the backflow inhibitor ( 3 ) having a closing element ( 5 ) that in a closed position lies tightly on a valve seat ( 6 ) of the cartridge housing ( 2 ) and can be moved from the closed position against a return force into an open position, a guide pin ( 7 ) protrudes from a downstream side of closing element ( 5 ) and is guided in a guide opening ( 8 ) of a central regulator core ( 9 ) of the flow regulator ( 4 ), and the flow regulator ( 4 ) having a regulator element ( 10 ), made of elastic material, that surrounds the regulator core ( 9 ) and that lies on an annular shoulder ( 11 ) or a regulator element support member, and that limits, between the regulator element ( 10 ) and an enclosing wall situated opposite thereto, a control gap ( 12 ) that changes in a manner dependent on pressure, wherein the flow regulator ( 4 ) terminates approximately flush with the downstream side of the cartridge housing ( 2 ), and annular shoulder ( 11 ) or regulator element support member protrudes from the regulator core ( 9 ), and the control gap ( 12 ) is provided between the regulating element ( 10 ) and an inside of the cartridge housing which forms the enclosing wall.
