  • Suction controlled pump for HEUI systems
    Patent number: 6672285
    Abstract: A HEUI system uses a fixed displacement, radial piston pump to provide a generally constant pump flow of high pressure hydraulic fluid over the operating speed range of the radial piston pump to minimize parasitic power drains on the engine. The radial piston pump includes an orificing suction slot to vary the pump displacement over the operating speed of the pump. A throttling valve at the pump inlet may be provided to starve inlet fluid feed if reduced flow to the injectors is additionally required.
    Type: Grant
    Filed: April 16, 2002
    Date of Patent: January 6, 2004
    Assignee: Bosch Rexroth Corporation
    Inventors: Brian William Smith, Eric D. Ramseyer, Mark Douglas Correll
