Abstract
This invention relates to an apparatus for feeding pressurized fluid by a constant c. c. pump and a variable c. c. pump, both driven by a single motor. A valve actuated by a centrifugal governor ensures the feed of a jack adjusting the position of the member for adjusting the cubic capacity of the variable c. c. pump. One application is the drive of pumps of which the sum of the maximum powers is greater than the maximum power of the motor.
