The utility model relates to the technical field of hydraulic oil cylinders. The pure hydraulic control differential pressure induction automatic reversing device comprises an oil tank, a base is fixedly connected to the bottom of a reversing valve, transition pipes are fixedly connected to the left side and the right side of the reversing valve, an inlet filter block is rotatably connected to thefront face of the reversing valve, and filter blocks communicate with the separated sides of the two transition pipes. The invention discloses a pure hydraulic control differential pressure inductionautomatic reversing device for an oil cylinder. A differential pressure signal obtaining valve arranged at the top of the connecting pipe is communicated with the connecting pipe and the inserting plate; therefore, the operation state of the device is detected through the hole communicated with the differential pressure signal obtaining valve. The reversing valve and the one-way valve are connected through the transition
