A fuel filter includes a manifold, a connector element, a filter bowl, a filter element, an inlet shutoff valve, an outlet shutoff valve, an inlet port, an inlet passage, an outlet port, an outlet passage and a relief valve in which the connector element is fixed to the manifold, and the filter bowl is reversibly fixed to the connector element, the connector element and the manifold define a chamber and the chamber is split into a second inlet chamber and a second outlet chamber by the relief valve. The filter bowl is adapted to reversibly receive the filter element and is so configured that when the filter element is located within the filter bowl and the filter bowl attached to the connection element, the filter element divides the space defined by the connector element and filter bowl into an inlet filter chamber and an outlet filter chamber.

A water filtration system and water filtration system head provide interchangeable water inlet and outlet ports, so that a direction of a flow of water through the water filtration system can be reversed by configuring a valve provided in the water filtration system head that attaches to a cartridge housing containing a water filter cartridge. The head has a first fluid channel communicating with a fluid volume between the cartridge housing and the outer surface of a water filter cartridge, a second fluid channel in communication with an inside of the cartridge, and a multi-position valve that either conducts inlet water from a first port to the first fluid channel and conducts outlet water from the second fluid channel to the second port, or conducts inlet water from the second port to the first fluid channel and conducts outlet water from the second fluid channel to the first port.

A water sediment filter assembly includes a screen member and a drain port which permits the removal of collected debris. The water sediment filter assembly includes a valve member which can be moved to different positions to permit the draining of collected sediment through the drain port.

A filtration device, in particular a disposable filtration device, has a flow path in which a filter element and an integrated flow reducer are arranged one behind the other. The flow reducer is adapted to be brought to a first operating position, which permits a defined first volume flow rate, and at least to a second operating position, which permits a defined second volume flow rate which is smaller than the first volume flow rate.

A filter pulsation dampening device has a replaceable filter element including a plurality of baffles disposed next to each other or a flexible valve that is disposed proximate a baffle.

The present invention relates to fluid filtering apparatuses, for applications such as water filtration, that utilizes screen filters, and in particular, to such a filtering apparatus having autonomously controlled self-cleaning capabilities. A self-cleaning filter apparatus including a filtering housing for filtering a fluid across a screen filter, a flushing chamber for housing filtered debris, and a control assembly for autonomously switching between filtering phases of the filter based on the differential pressure across the filter that is channeled along portions of the control assembly, the control assembly including a flush valve assembly, a three position two way (3/2) valve and a differential pressure (DP) switch.

A filter cap includes a first end and a second end facing away from the first end. A first cylindrical projection projects from the first end of the filter cap and a second cylindrical projection projects from the second end. An annular recess is formed around the first cylindrical projection. The second cylindrical projection includes at least one peripheral groove for an O-ring and a plurality of radially inward extending ridges. A passageway extends through the first and second projections. The passageway has a first dimension in the first projection, a second dimension greater than the first dimension in the second projection near a distal end of the second projection, and a third dimension smaller than the second dimension within the second projection between the plurality of ridges.
