normally moves when the frame is mounted on the peripheral surface,
the frame defining an area of a selected shape therewithin;
a pleated filter media suitable for filtering transmission oil,
the pleated filter media being mounted within the area defined by the
mounting frame, the pleated filter media having pleats defined by
peaks and valleys which join panels extending in a selected direction
parallel to the selection [sic] direction of the frame, the valleys of
the filter media all lying in the same plane being positioned below
the mounting frame and the peaks rising to at least the bottom of the
frame and all lying in the same plane with the panels having a dirty
transmission oil side facing toward the mounting frame and a clean
transmission oil side facing away from the mounting frame; wherein
when the frame is mounted in the peripheral area of the sump, the
peaks, valleys and panels of the filter media extend in a direction
parallel to the direction in which the vehicle mounting the
transmission oil pan moves.
33. A panel-type filter element for filtering lubricating oil,
the filter element being adapted to be mounted on a peripheral surface
of a lubricating oil [pan] spaced from the floor of the pan, the
peripheral surface having a selected shape with respect to the
direction in which a vehicle mounting the lubricating oil pan normally
moves, the filter element being used to filter lubricating oil which
flows in a selected horizontal direction in the oil pan toward the
sump, the filter element comprising:
a mounting frame corresponding in shape to the selected shape of
the peripheral surface of the sump so as to be adapted to be oriented
in a selected direction parallel to the direction in which the vehicle
normally moves when the frame is mounted on the peripheral surface,
the frame defining an area of a selected shape therewithin;
a pleated filter media suitable for filtering lubricating oil,
the pleated filter media being mounted within the area defined by the
mounting frame, the pleated filter media having pleats defined by
peaks and valleys which join panels extending in a selected direction
parallel to the selection [sic] direction of the frame, the valleys of
the filter media all lying in the same plane being positioned below
the mounting frame and the peaks rising to at least the bottom of the
frame an all lying in the same plane with the panels having a dirty
lubricating oil side facing toward the mounting frame and a clean
lubricating oil side facing away from the mounting frame; wherein when
the frame is mounted in the peripheral area of the sump, the peaks,
valleys and panels of the filter media extend in a direction parallel
to the direction in which the vehicle mounting the lubricating oil pan
moves.
