摘要： THE PRESENT INVENTION RELATES TO AN HYDRAULIC MOTOR HAVING A NUMBER OF PISTONS ARRANGED FOR RADIAL MOTION IN A CYLINDER BLOCK WHICH PREFERABLY FORMS THE STATIONARY PART OF THE MOTOR. THE PISTONS ARE, OVER PISTON RODS EXTENDING OUTWARDLY OF THE PISTONS, CONNECTED TO CAM ROLLERS ARRANGED FOR COOPERATION WITH AT LEAST ONE CIRCUMFERENTIALLY CLOSED CAM CURVE RADIALLY SURROUNDING SAID CAM ROLLERS. THE CAM CURVE IS RADIALLY CONNECTED TO THE MOTOR CASING AND ROTABLE RELATIVELY THE CYLINDER BLOCK. THE NUMBER OF CAMS ON THE CAM CURVE IS DIFFERENT FROM THE NUMBER OF PISTONS. THE PISTONS ARE ARRANGED UPON SUPPLY OF A PRESSURE FLUID TO WORKING CHAMBERS LOCATED RADIALLY INSIDE THE PISTONS TO CAUSE THE CAM CURVE AND THEREBY ALSO THE MOTOR CASING TO ROTATE RELATIVELY THE CYLINDER BLOCK.
