Therefore, the cylinder body of the rotary vane type hydraulic steering engine is divided into a high-pressure area and a low-pressure area through the movable vane, the fixed vane and the sealing ring. However, three seal rings of the movable vane are formed by splicing only, and vulcanization treatment cannot be carried out on site, so that a leakage point is formed at the spliced position, and thus, leakage occurs inside the rotary vane type hydraulic steering engine, namely, leakage is formed between a high pressure area and a low pressure area, and the steering sensitivity and stability are affected.

According to the technical scheme of the invention, the movable vane group sealing device comprises a sealing ring pressing plate, two sealing rings and a movable vane, wherein the movable vane is connected to a rotor through a connecting bolt; one side of the sealing ring is provided with a lip opening which turns outwards, and the sealing ring is provided with a notch.
As a further improvement of the invention, an annular groove structure is arranged on one side of the sealing ring connected with the sealing ring pressure plate, the lip of the annular groove is arranged to turn outwards, and the inner wall of the annular groove is arranged to turn inwards.
As a further improvement of the invention, the notch is positioned at the bottom of the annular groove and is arranged to penetrate along the bottom of the annular groove.
As a further improvement of the invention, the movable blade groups have at least two groups.
The hydraulic steering engine has the advantages that the internal sealing performance of the rotary vane type hydraulic steering engine is improved, the internal leakage of hydraulic oil of the rotary vane type hydraulic steering engine is solved, the steering stability of the hydraulic steering engine is greatly improved, the steering flexibility of the rotary vane type hydraulic steering engine is improved, and all the advantages of the original rotary vane type hydraulic steering engine are reserved.
