Abstract: The replaceable, outside-in flow filter element with integral annular trap provides a simple, efficient, tubular filter element that combines the advantages of inside out-flow and outside-in flow filters. The element includes end caps with pleated filter media extending there between. A solid tube is secured between the end caps in a position spaced radially outward from the media. The annular space between the media and the tube forms an integral, lateral, outer trap for containing filtered out particulate matter. The trap allows the particulate to be removed with the used filter element during conventional replacement. The inlet end cap includes openings spaced from an end of the filter media whereby a portion of the openings overlap the media in plan view such that inflow through this overlapping portion of the openings will flow radial outward in the space between the openings and the filter media to the annular space.

Abstract: A strainer system having two separate strainers positioned in parallel, where one strainer can be cleaned while still permitting normal flow through the other strainer. The system flow circuit is arranged so that a high pressure backwashing flow can be applied to one strainer while the other strainer is providing its normal straining function. The backwashed strainer is then isolated by valves so that its access flange can be removed and the particulate buildup within the valve plug cleaned out. The strainer is then returned to service following the replacement of the access flange. In this manner, it is possible to alternate between the two strainers so that continuous flow can be maintained to the hydraulic choke located downstream of the strainer system.

Abstract: An oil filter assembly has an outer canister in which full flow and bypass flow filtration sections are operatively housed in a nested relationship. Oil forced into the canister has imparted thereto a vortex flow pattern which forces contaminant particles in the oil away from the full flow filter section before the oil passes therethrough. The bypass filtration section is disposed within the full flow filtration section and creates a second vortex flow pattern in the oil which induces a small portion thereof to flow through a bypass filter element while at the same time causing the entire balance of the oil to bypass this filter element and be discharged from the canister after having traversed the filtering portion of only the full flow filtration portion of the filter assembly.

Abstract: A means separates solid matter from liquid and includes a perforated separation panel through which the liquid can pass and which prevents the passage of the solid matter of a size larger than a predetermined size. When solid matter becomes located against the panel, the flow of liquid along the face of the panel on which the solid matter is located will tend to cause the solid matter to move from the panel so that the panel is self cleaned and does not become obstructed by the solid matter.

Abstract: A filter for a fuel injection device, comprising a plurality of filter elements arranged within a housing such that, in use, fluid is directed through clearances of predetermined size between respective mutually adjacent ones of the elements for preventing the passage of oversized contaminant particles carried in the fluid.

Abstract: The fluid treatment apparatus may comprise a sedimenter or agglomerator for insertion in a fuel line between a fuel tank and a fuel injection pump in order to remove dirt particles and water from diesel fuel passing along the fuel line. A water reservoir (4) is positioned at the bottom of the apparatus in order to collect the water removed from the fuel. In order to avoid applying a compressive clamping force to the side wall (17) of the water reservoir (4), the arrangement is such as to clamp only the top part of the side wall (17) ?as shown in FIG. 1! or else to apply no clamping force at all to the water reservoir (4) ?see FIG. 16!. This enables the water reservoir (4) to be made of cheap plastics material.

Abstract: Removal of a first liquid, such as water, from a tank containing a second liquid of lower specific gravity, such as diesel fuel, is achieved with a liquid trap chamber into which the first liquid is delivered by a primer wick and from which the first liquid is withdrawn by an exhaust wick or pump. The primer wick transversely fills an in-flow passage above a downward-facing inlet opening of that passage. The first liquid is drawn from the tank by the primer wick, which spills that liquid over a weir into the liquid trap chamber. The bottom of the liquid trap chamber is disposed at a level below said inlet opening. The exhaust wick is disposed to transversely fill an outlet passage disposed above the liquid trap chamber with the bottom of the exhaust wick or pump sensor positioned at least as high as the top of the primer wick.
