Abstract: An apparatus and a method are provided for a high capacity oil filter configured to remove contaminants from engine oil flowing within an internal combustion engine. The oil filter comprises a hollow canister having a length and a diameter suitable for housing a large filtration medium. A base gasket forms a fluid-tight seal between the oil filter and the engine. A base plate circulates oil from the engine through the oil filter. An anti-drainback valve prevents oil from draining out of the filter and passages within the engine when the engine is not operating. A key aspect of the present disclosure is that the relatively large dimensions and the configuration of the filtration media provide a large surface area for entrapping contaminants flowing with the engine oil.

Abstract: A vacuum filter device comprising a filter body having two holders on opposite sides of a filter. Each holder contains a closed container in a fluid-tight, sealed relationship. The filter is retained by a compression sealing element and the sealing element is maintained in place by a compression element formed of a ring. The compression element is bonded to a portion of the body to hold it, the sealing element and filter in place under a compression seal. Optionally a port in the compression element is formed to align with the vent of the device. Further, an alignment feature on the compression element ensures the port is in alignment with the vent of the device. The device also includes a vacuum port communicating with the downstream side of the filter, and hence the filtrate container.

Abstract: Disclosed herein is an end-cap structure of an oil filter for vehicles. The end-cap includes a base cap which has a hole in a central portion thereof, and a hook cap which is installed in the hole so as to be movable upwards or downwards. In this structure, a surface of the hook cap that comes into contact with the base cap when the hook cap moves upwards is a sealing portion. When the hook cap moves downwards, the sealing state is released and a bypass is formed. According to the structure of the present invention, since the sealing portion of the end-cap can be protected from heat, the quality of the product, the productivity, the economic efficiency, etc. can be enhanced.

Abstract: A filter system having a filter media retainer seal includes: at least one underdrain block having a top wall, a bottom wall, and a pair of side walls extending between the top wall and the bottom wall; a filter media retainer mounted onto the top wall of the at least one underdrain block; and at least one rib positioned between the underdrain block and the filter media retainer. The at least one rib forms a seal between the underdrain block and the filter media retainer, and prevents filter media from entering the underdrain block. The at least one rib can be monolithically formed to the at least one underdrain block. Alternatively, the at least one rib is monolithically formed to the filter media retainer. The rib is crushable and/or it bites into a surface on the adjoining part to reduce or eliminate the need for a separate sealant.
