Abstract: A compact filter element with a large filter surface area having inner and outer rings of filter material with an annular space between them, such that fluid to be filtered can be introduced into the annular space between the rings of filter material and a portion thereof can flow through the outer ring of filter material to the periphery of the filter element and another portion thereof can flow through the inner ring of filter material to the center of the filter element; at least one fluid-permeable support member for the filter material, and at least one end disk on an axial end face of the filter element affixed to the rings of filter material in a sealed manner, in which the end disk has a centrally arranged inlet opening for the fluid to be filtered and one or more radially extending distributor channels leading from the central inlet opening to at least one eccentrically arranged outlet opening which opens into the annular space between the rings of filter material to admit fluid to be filtered to the

Abstract: An oil filter for an internal combustion engine with a cup-shaped housing that is releasably connectable to a receiving head. The housing has a first interlocking element that extends across at least a portion of the outer circumference of the housing and is interrupted by at least one axially extending recess. The filter element has a liquid-tight canister provided on its outer surface with second interlocking elements, which fit into the recesses of corresponding first interlocking elements when the filter element is installed in the housing.

Abstract: A filter has a filter housing and a receptacle chamber in the filter housing into which a filter element is insertable. The filter housing has a housing cover for opening and closing an opening of the receptacle chamber. The housing cover is situated in an area of the filter housing between the oncoming flow side and the outgoing flow side of the filter element.
