    摘要: A hydraulic-powered motor for stepwise operation has a plurality of radial pistons in a rotatable cylinder block, the pistons engaging a cam track having a number of indentations which is different from the number of the pistons. Electrically operated valves are provided and are energizable in sequence to apply pressure pulses to the pistons to cause stepwise rotation of the cylinder block. Detent means may be provided to prevent rotation of the cylinder block in the absence of a pressure pulse to any one of the pistons.
