mit einem auswechselbaren Filtereinsatz,
und mit einem den Filtereinsatz stützenden Stützdom,
und mit einem im Stützdom angeordneten Filterumge­ hungsventil,
wobei ein Ventilkörper des Filterumgehungsventils mit ei­ ner Dichtfläche zusammenwirkt, die
  • - von einer Endscheibe des Filtereinsatzes gebildet ist,
  • - eine vom Ventilkörper verschließbare Öffnung aufweist,
  • - und die während des Filterbetriebs grundsätzlich orts­ fest angeordnet ist, jedoch vom Ventilkörper entfernbar ist, wie bei Wartungsarbeiten am Filter,
dadurch gekennzeichnet, dass an dem Filtereinsatz ein Sieb vorgesehen ist, welches der in der Dichtfläche vorge­ sehenen Öffnung vorgeschaltet ist. 1. liquid filter,
with a replaceable filter insert,
and with a support dome supporting the filter insert,
