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 one-piece integral rotomolded hydraulic reservoir includes a plastic container body defining a container cavity for receiving hydraulic fluid. An insertable baffle is positioned in the container cavity through an access manway formed in the container body and is removable therefrom. The container body includes holding members for positioning and holding the baffle in place.

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: A rotomolded hydraulic reservoir includes a plastic container body defining a container cavity for receiving hydraulic fluid and forming a filter cavity in fluid communication with the container cavity. An insert, such as an aluminum bushing, is molded in the container body adjacent the filter cavity and a removable filter element positioned with the filter cavity and coupled to the insert.

Abstract: A rotomolded hydraulic reservoir includes a plastic container body defining a container cavity for receiving hydraulic fluid and forming a filter cavity in fluid communication with the container cavity. An integral baffle extends inwardly and is formed as part of an outer wall of the container body. The baffle controls the fluid flow pattern within the container cavity to provide deaeration and homogenization to the fluid.

Abstract: A filter element for separating a water from a petroleum-based fluid, the filter element having a hollow, fluid permeable porous support structure, a fluid permeable first ceramic coating positioned adjacent to the support structure, and a fluid permeable second ceramic coating positioned adjacent to the fluid permeable first ceramic coating, and a thin film of dry petroleum-based fluid, wherein the thin film of dry petroleum-based fluid substantially coats the filter element and permeates the fluid permeable porous support structure, the fluid permeable first ceramic coating, and the fluid permeable second ceramic coating, the dry petroleum-based fluid having a water content of approximately 100 ppm or less.

Abstract: A rotomolded hydraulic reservoir includes a plastic container body defining a container cavity for receiving hydraulic fluid and forming a filter cavity in fluid communication with the container cavity. One or more fluid return lines extend to a depth below the normal fluid level in the container cavity, with the filter cavity forming one of the return lines.
