摘要:
A self-cleaning filter includes a housing disposing a filter media having a permeable sidewall and an axial bore connected with the inlet conduit, a sleeve connected in-line with the axial bore and downstream of the inlet conduit, and a shuttle having a piston moveably disposed in the sleeve and an upstream element carrying a scraper disposed with the axial bore, whereby the hydraulic fluid flows from the inlet conduit through the permeable sidewall into the housing annulus and the hydraulic pressure in the axial bore applies a downward force on the shuttle. The scraper is moved downstream within axial bore to clean the filter media when the downward force due to the increased differential pressure across the filter media exceeds an upstream shuttle force.
