  • Patent number: 10077788
    Abstract: A fluid storage reservoir that creates a regenerative loop inside the reservoir to maintain a pressurized main suction chamber of the hydraulic fluid reservoir is provided. This reservoir includes two separate chambers which are operably fluidly connected by one or more check valves. In the main suction chamber, the design arranges the return flow larger than suction flow in order to pressurize this chamber. This pressure can be adjusted by the check valve setting. This regenerative reservoir can provide sufficient pressure when large system flow occurs.
    Type: Grant

  • Publication number: 20160251156
    Abstract: A new and improved fluid storage reservoir that includes a wave suppression plate is provided. The wave suppression plate inhibits entraining air into fluid stored within the fluid storage reservoir by inhibiting wave formation and splashing of the fluid at the fluid-to-air interface within the fluid storage reservoir. The wave suppression plate is configured to inhibit mixing between a portion of fluid having a lower entrained amount of air below the wave suppression plate and a portion of fluid having a higher entrained amount of air above the wave suppression plate.
