ABSTRACT:
A filter and associated valve are provided which are particularly useful for the purification of oil or fuel in an internal combustion engine. The filter includes a preassembled valve unit having a sealing member, an activating member and an interposed spring element formed without a housing. The sealing member and activating member penetrate each other along a part of their axial length, guiding each other and being displaceable relative to each other in an axial direction. The relative axial displaceability is limited by a stopper provided at the activating member and/or the sealing member. The preassembled valve unit is guided axially moveable in a drain conduit of the filter after insertion of the valve unit into the conduit.
