    Abstract: A constant pressure variable displacement axial piston pump employing two stroking cams and two banks of opposed pistons mounted in circular array in rotary cylinder barrels positioned on opposite sides of a flat port plate. The stroking cams and piston slippers have arcuate concave cam and convex bearing surfaces, respectively, formed about an axis which intersects and is perpendicular to the axis of rotation of the cylinder barrels. With this construction, each piston will be forced through two strokes per revolution of the cylinder barrels, all radial forces will be in inherent balance, and there will be an area contact between the piston slippers and the stroking cams at all times.

    Abstract: THE DISCLOSED BARREL-TYPE ENGINE INCLUDES A PLURALITY OF PREFERABLY GENERALLY KEYSTONE-SHAPED PISTONS ARRANGED ANNULARLY WITHIN AN ELONGATE HOUSING OF GENERALLY CIRCULAR CROSS SECTION. THE PISTONS ARE ARRANGED FOR PARALLEL LONGITUDINAL RECIPROCATION SIMULTANEOUS WITH THEIR ROTATION WITHIN AND ABOUT THE HOUSING. THIS COMBINATION OF RECIPROCATORY AND ROTARY MOTION IS TRANSLATED TO A LONGITUDINALLY EXTENDING SHAFT THROUGH A CAM COUPLING CIRCUMSCRIBING THE HOUSING AND HAVING LONGITUDINALLY EXTENDING UNDULATIONS. PREFERABLY BOTH ENDS OF THE PISTONS ARE WORKING ENDS.
