ABSTRACT:
The present invention provides a single band disposed within the interior chamber of an elongated housing. The band is engageable with the interior wall of the housing, such that the band straddles an elongated slot passing through the housing of the fluid actuated motor. Seal members are disposed on both sides of the slot facing inwardly to engage with the single interior band to provide sealing of the slot in the pressurized areas of the rodless fluid actuated motor. In the preferred embodiment, overall load moving capability of the rodless fluid actuated motor is increased by providing an elliptical or oval-shaped piston reciprocally mounted within a correspondingly-shaped longitudinal aperture formed within the housing. Preferably, the slot passing through the housing is disposed along a generally flat planar portion of the longitudinal aperture, such as along the generally planar portion of the elliptical surface.
