This paper relates to the increase in speed and pressure ratings of piston type hydraulic pumps and motors. Such units are typically used as components in hydrostatic transmissions. Without a substantial change in basic design, the introduction of fixed losses to fulfill these ratings adversely affects the partial load efficiency of those units.
