Swash Plate Pump

This is a still representation and possibly also a low-resolution image of a fully animated pump.        Swash plate pumps have a rotating cylinder containing pistons. A spring pushes the pistons against a stationary swash plate, which sits at an angle to the cylinder.      The pistons suck in fluid during half a revolution and push fluid out during the other half.      Shown on edge on the far right in the animation is a dark stationary disk. It contains two semi-circular ports. It is shown again in a head-on view below, left.    This is a still representation and possibly also a low-resolution image of a fully animated pump.        These ports allow the pistons to draw in fluid as they move toward the swash plate (on the backside and not shown here) and discharge it as they move away.      For a given speed swash plate pumps can be of fixed displacement like this one, or variable by having a variable swash plate angle. The greater the slant the further the pistons move and the more fluid they transfer.      Note similarities to, and differences from, the wobble pump, radial piston pump, and bent axis pump.
