    摘要： A filter for filtering fluid has a filter housing with fluid inlet for fluid to be filtered and fluid outlet for filtered fluid. A filter element arranged in the filter housing separates fluid inlet fluidically from fluid outlet. A bypass valve arrangement is arranged fluidically between fluid inlet and fluid outlet such that it fluidically connects in an open state fluid inlet to fluid outlet. The bypass valve arrangement has a valve closure body arranged movably in the valve housing between a closed position and an open position. The bypass valve arrangement has a valve seat element with valve seat. The valve closure body rests sealingly at the valve seat in closed position. The valve seat element is connected to a part of the valve housing by a mechanical connection realized by relative rotation between valve seat element and part of the valve housing about a valve axis.

    摘要： A fluid treatment device has an exchangeable treatment unit and a connection head. A bayonet-type connection device connects connection head and treatment unit to each other by a plug-in/rotation movement about a connection axis of the treatment device and is provided with a housing connection part and a head connection part that operatively engage each other to form a connection of the bayonet-type connection device. Housing connection part and head connection part each have a mutually complementary functional element extending circumferentially about the connection axis and operatively connectable to each other. One functional element has an assembly ramp passing into a first support region perpendicular to the connection axis. The other functional element has a slide region adjoined by a second support region perpendicular to the connection axis. In connection end position, first and second support regions are positioned on top of each other relative to the connection axis.
