    Patent number: 3968650
    Abstract: A fluid feed device comprising a constant cylinder capacity pump and at least one variable cylinder capacity pump driven from a single prime mover, the variable cylinder capacity pump being provided with a regulator for reducing its cylinder capacity as the feed pressure increases. The regulator is such as to reduce the power absorbed by the variable cylinder capacity pumps as the pressure increases by an amount equal to the increase in the power absorbed by the constant cylinder capacity pump such that the total power absorbed by the pumps remains constant and equal to the power of the prime mover.
