Abstract
This invention relates to a liquid filter which includes a housing and a rotatable lid for covering the opening in the filter housing. The housing incorporates the inlet port and the outlet port for the filter. The lid is secured to the housing by rotating movement in which cam followers carried by the lid engage cam members carried by the housing to cause the lid to be cammed downwardly upon the housing. As the lid is drawn down onto the housing, an annular seal carried by the lid engages the inner surface of the housing to form a seal between the lid and the housing, covering a side opening in the housing.
