PUMP , AXIAL PISTONS
Definition:
A POSITIVE DISPLACEMENT DEVICE WHICH UTILIZES THE RECIPROCATING MOTION OF A MULTIPLE NUMBER OF PARALLEL PISTONS ARRANGED AXIALLY IN A CYLINDER BARREL AS A MEANS OF TRANSFERRING A LIQUID FROM ONE PLACE TO ANOTHER. THE PISTONS ARE ACTUATED BY REVOLVING THE CYLINDER BARREL AT AN ANGLE TO THE DRIVE SHAFT AXIS OR BY A TILTING BOX WHEN THE CYLINDER BARREL REVOLVES ON THE DRIVE SHAFT. THE PISTON DISPLACEMENT MAY BE FIXED OR VARIABLE. IT IS DESIGNED TO BE DRIVEN BY A PRIME MOVER WHICH IS NOT AN INTEGRAL PART OF THE PUMP.
