the oil generally flows into the can from the top line thru the filter media from the outside ( this is the greatest amount of filter surface area ) to the inner tube and back to the spool valve. The spool valve opens with the right amount of pressure ( about 45 psi I think) and the oil simply dumps bake to the pan.
