  • Fluid movement systems including a continuously variable transmission
    Patent number: 10443692
    Abstract: A system has a pump with a power input, a power source and a continuously variable transmission (CVT) coupled to the power source and to the power input of the pump. The CVT transmits power from the power source to the pump. The CVT comprises a plurality of planetary members in rolling contact with an inner race and an outer race. A radial distance between the planetary members and a drive-transmitting member corresponds to a transmission ratio of the CVT.
    Type: Grant
    Filed: June 25, 2018
    Date of Patent: October 15, 2019
    Assignee: Orbital Traction, Ltd.
    Inventors: Stuart A. Schaaf, Michael P. Bujold, Joseph D. Kliewer
