Variable displacement axial piston pump of swash plate design The
Series 42 pumps are advanced hydrostatic units designed for "medium
power" applidieselions with maximum loads of 350 bar (5000 psi).
These pumps can be combined with a suitable Sauer-Sundstrand motor
or other products in a system to transfer and control hydraulic
power. The Series 42 variable displacement pump is a compact, high
power density unit, using the parallel axial piston / slipper
concept in conjunction with a tillable swash plate to vary the
pump's displacement. Reversing the angle of the swash plate
reverses the flow of oil from the pump, and thus reverses the
direction of rotation of the motor output. Series 42 pumps provide
an infinitely variable speed range between zero and maximum in both
forward and reverse modes of operation. Series 42 pumps utilize a
cradle swash plate design with a hydraulic servo control cylinder.
Control is provided through a compact servo control system. A
choice of servo controls are available.
These include mechanically- or electrically-actuated feedback
controls, hydraulic or electric proportional controls, and a
three-position electric control. These controls are designed for
low hysteresis and responsive performance.
