  • Patent number: 4982566
    Abstract: The present invention is an expander band for use in hydraulic pumps, motors, and hydrostatic transmissions. The band has a plurality of elongated slots located circumferentially which receive slippers attached to pistons. One reduced dimension slot fixes the position of a slipper relative to the expander band while the other slippers move within the elongated slots. The fixed slipper limits the range of movement of the other slippers relative to the band, and thus the slippers avoid abutting the side ends of the elongated slots.
