Abstract: A device for cooling and filtering hydraulic fluid comprises a first chamber that includes a fluid inlet connection, a filter cartridge, a bypass manifold, and an inlet to a cooler; and, a second chamber that includes an outlet from the cooler and a fluid outlet connection. The cooler interconnects the first and second chambers through the inlet of the first chamber and the outlet of the second chamber. The bypass manifold is configured to return fluid entering the fluid inlet connection to the fluid outlet connection when a first pressure differential at the bypass manifold is above a first value, and to pass the fluid onto the filter cartridge when the first pressure differential at the bypass manifold is at or below the first value.

Abstract: The interactive doll simulates the character of a live person or, in other embodiments a fantasy figure or animal, in essence, simulating a living being that possesses respective human or animal qualities: displaying specific needs, tenderness, intelligence and/or understanding.
