  • Reverse fin cooling fan
    Patent number: 9926832
    Abstract: An engine assembly includes a crankcase, a shaft, a housing, and a cooling fan. The shaft is coupled to the crankcase and defines a rotational axis. The housing has a sidewall that defines an internal space. The cooling fan is disposed at least partially within the internal space and is coupled to the shaft. The cooling fan includes a plate defining an upper surface and a lower surface. The plate is positioned to rotate with the shaft about the rotational axis. The cooling fan also includes a band that has an inner band radius and an outer band radius. The cooling fan also includes a plurality of reversed fins coupled to the band and extending from the upper surface of the plate, further radially outward from the rotational axis than the band.
