  • Electric motor pump system and method
    Patent number: 11692541
    Abstract: An electric motor pump system includes a variable displacement pump, an electric motor connected to drive the variable displacement pump, a first control piston configured to limit an output pressure characteristic of the pump, and a second control piston controlled via a servo valve according to an output speed of the electric motor. In embodiments, the second piston is configured to maintain a substantially constant output flow of the pump as the output speed of the electric motor changes. With embodiments, the first and second control pistons may be configured to act on a yoke of the variable displacement pump.
