  • Patent number: 6619310
    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.
