This invention relates to an improved torque amplification device using alternating flow hydraulics and orbital rotary piston motor principle comprising a pump (401) having the characteristics of an inline linear piston type pump, having a rotary swash plate (110, 123) and a barrel (104) fixed to a stationery housing (109), and a plurality of chambers (102) a motor (402) having the characteristics of an epitrochoid generated ORBIT type motor having a cardan shaft (213), an output shaft (216), and a plurality of chambers (227); said motor having a cover plate (229, 416) with corresponding number of through connecting holes (222) accessing said plurality of chambers; a feed pump (407); and a feed valve (410) integrated with one of the end covers of the pump or the motor. In that each pump chamber of said plurality of pump chambers being flowably connected with respective chambers of said motor by a plurality of individual pipings (403 - 406) thereby amplifying the torque input through said swash plate by the gearing ratio of said motor.
