the first plurality of openings are disposed on a first area of the filter member and the second plurality of openings are disposed on a second area of the filter member, the first area is configured to be disposed closer to an inlet fluid stream than the second area.
11. The power steering tank baffle of claim 1 , wherein
the hood member is configured to change a direction of a fluid entering a power steering tank.
12. A power steering tank baffle, comprising:
a filter member including an inflow portion and an outflow portion, the inflow portion including a first plurality of openings having a first flow path and a second plurality of openings;
a hood member disposed over the inflow portion to cover the first or second plurality of openings; and
a rib member connecting the filter member and the hood member and extending along the inflow portion adjacent at least two openings of the second plurality of openings and separating the first plurality of openings and the second plurality of openings, the rib member being configured to direct a first portion of a fluid passing through the first plurality of openings in a first direction and a second portion of the fluid passing through the second plurality of openings in a second direction, the first direction being opposite the second direction,
the first plurality of openings and the hood member being disposed such that power steering fluid is capable of passing through the first plurality of openings along the first flow path, and then contact the hood member so as to be directed through an open area along a second flow path at least in the first direction, the second flow path being transverse to the first flow path.
13. The power steering tank baffle of claim 12 , wherein
the rib member is disposed on the inflow portion so as to separate the first plurality of openings and the second plurality of openings.
14. The power steering tank baffle of claim 12 , wherein
the outflow portion has a surface area that is greater than a surface area of the inflow portion.
15. The power steering tank baffle of claim 12 , wherein
the hood member is disposed such that a radial inner edge of the hood member is disposed radially closer to a center of the filter member than radial inner edges of the first plurality of openings and the second plurality of openings.
16. The power steering tank baffle of claim 12 , wherein
the filter member is configured to be disposed within a power steering tank such that when a fluid enters the power steering tank, the fluid contacts an underside of the filter member adjacent the first plurality of openings.
