Abstract
A cartridge insert for insertion in a fluid line is provided having a cartridge housing within which is located at least one backflow inhibitor and downstream at least one flow regulator. The backflow inhibitor has a closing element, which, in a closed position thereof, lies tightly sealed on a valve seat of the cartridge housing and which may be displaced from the closed position against a return force into an open position. A downstream guide pin projects from the closing element, and extends into a guide opening of a central regulator core of the flow regulator, and the flow regulator is formed from a regulator element made from an elastic material that surrounds the regulator core, which rests on an annular shoulder and defines a control gap, which changes with pressure between the above and an opposing enclosing wall. The cartridge insert is compact and space saving in that the flow regulator terminates generally flush with the downstream side of the cartridge and the annular shoulder projects from the regulator core and the control gap is provided between the regulating element and an inside of the cartridge housing which forms the enclosing wall.
