Abstract
A replaceable filter cartridge assembly for a liquid filter and a liquid filter in which such a filter cartridge is installed. The filter cartridgeis provided with a support elementand a seatfor a sealing membraneis provided on the support elementThe sealing membrane seals the inletof the housing via a sealing edgethat acts as a return flow barrier over the inlet. The sealing membranealso has a radial sealing surfaceto provide a seal between the support elementand the outlet portof the filter. This permits the filter cartridge to be manufactured in a particularly cost-effective manner and assures simple mounting within the housing. Since only the filter cartridge, which can be pushed onto the support elementneeds to be exchanged, very little material has to be disposed of when the filter is replaced, which further increases the cost-effectiveness of the filter in use.
