  • Return diffuser for hydraulic tank
    Patent number: 8991422
    Abstract: A diffuser assembly for a hydraulic reservoir is disclosed. The diffuser assembly includes an inlet tube for connection to the inlet to the reservoir. A middle portion of the middle tube is connected to a plurality of diffusers. The diffusers are disposed at an angle with respect to an axis of the inlet tube and the axis of the inlet to the reservoir so that fluid flowing into the reservoir must change flow directions for entering and exiting the diffusers. The disclosed diffuser assembly is less prone to damaged cause by fluid flow spikes and is particularly useful for high flow/high pressure applications.
