  • Patent number: 9927026
    Abstract: A neutral biasing mechanism in a hydrostatic continuously variable transmission includes a plurality of springs attached so as to be spanned from a pivot arm to a base. The plurality of springs bias the pivot arm such that a roller is fitted into a cam portion. A variable spring configured such that a biasing force thereof can be changed and another spring that is different from the variable spring are provided as the plurality of springs. The variable spring and the other spring are arranged at separate positions in a state where attachment positions thereof in the pivot arm and the base are separate from each other.
    Type: Grant

  • Patent number: 7712684
    Abstract: A fuel injection valve which injects fuel from a nozzle hole includes a cavitation generation flow path in which a cavitation bubble is generated in fuel flowing inside the injection valve, and a bubble storage flow path which is connected to the cavitation generation flow path and the nozzle hole and which stores the cavitation bubble generated in the cavitation generation flow path. A fuel containing the cavitation bubble stored in the bubble storage flow path is injected from the nozzle hole so that atomization of an injected fuel spray is enhanced.
