Abstract: A hydraulic filter includes a canister extending along the longitudinal axis. A closed end cap is at one end of the canister for closing one end thereof. A removable filter element is contained within the canister and a modular one-piece input end cap is at an end of the canister. The one-piece input end cap includes a hydraulic input chamber and a hydraulic output chamber which can be positioned in any one of three mutually perpendicular directions. The one-piece input end cap also allows for sensors to be positioned in any one of three mutually perpendicular directions. In addition, the one-piece input end cap can be utilized in base-ported or top-ported configurations while also allowing for side-to-side or side-to-end configurations.

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 top or bottom mounted, in-line, in-tank return line filter element is mounted in a hydraulic reservoir. The reservoir includes a holding tank, at least one outlet extending from and one return line extending to the reservoir, an in-tank return line within the reservoir and extending to one return line, and an in-tank return line filter element mounted within the in-tank return line. The in-tank return line filter element includes an end cap, a filter media and a by-pass valve coupled thereto. The end cap includes a central fluid opening, a mounting surface for the filter media, and a peripheral attaching mechanism for attaching the filter element to the in-tank return line to form a filter assembly. The mounting surface is positioned between the central opening and the attaching mechanism such that an in-line, in-tank filter element is provided.

Abstract: A portable, controllable fluid filtration flushing system with automated feedback, remote access, and documented operation is designed for hydraulic fluid or the like and has a base mounted on wheels for transporting the system. A filtration system mounted on the base is connectable to the hydraulic fluid system of the machine to be flushed. Feedback sensors mounted on the base, such as a particulate sensor or particle counter, are coupled to the filtration system. A programmable logic controller (PLC) is mounted on the base to control and document the operation of the flushing system. An operator input mechanism, such as a touch screen or keypad, may be on the base. The PLC is remotely accessible by an operator such as through the Internet, hardwire connection, RF connection, or the like.

Abstract: A high pressure filter cap configured to withstand a high pressure differential and to minimize the deposit of residue on the filter cap threads. The body of the cap has, protruding from its lower surface, two circular flanges concentrically arranged about a central axis. The outer flange is threaded on its inner surface to engage the threads of a filter housing. The inner flange accommodates, on its outer surface, a sealing component such as an o-ring. A retainer, removably attached to the cap, holds the sealing component in place.
