  • Engine oil pump including plunge pool to mitigate surge noise
    Patent number: 9074500
    Abstract: An engine oil pump, may include a plunge pool formed in a pump case and preventing a rapid change in pressure of oil when the oil may be discharged through an oil discharge portion that may be a cross-section expansion section by generating vortex flux when oil, which may be pumped into an oil pocket by rotation of an inner rotor and an outer rotor, temporarily collects before being discharged after passing a cross-sectional reduction section, and reducing the pressure by consuming the energy of the oil increasing in pressure by the vortex flux.
    Type: Grant
    Filed: October 31, 2011
    Date of Patent: July 7, 2015
    Assignee: HYUNDAI MOTOR COMPANY
    Inventors: Byunghwan Jung, Wonjo Jeong
