ABSTRACT:
An oil filter assembly for an internal combustion engine includes a body (31) which provides inflow and delivery passages and an attachable filter element container (45) which is attached to the body by a screw-thread at its open end to enclose a cylindrical pleated paper filter element (41) which is located by a perforated support tube (35) carried by the main body, the filter element (35) is sealed at one end against the body and is axially positioned by a spring (38) acting between the closed end of the container and a disc-like closure member (42) which thereby maintains engagement between one end of the filter element and the main body and sealing closure of the other end of the filter by the closure member sealing, the radial and axial compression of the filter element being limited by the support tube.
