[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A rotary valve of a diesel engine includes an engine. A side plate is installed at one end of the engine. A through hole is opened at the axial center of the end face of the side plate. On the upper part of the outer wall of the engine, cylinder cavities are installed on both the left and right sides. A box cover is installed on the cylinder cavity. A output rod is rotatably connected in the through hole. A crank one and a crank two are respectively installed at the end of the output rod. Hinge rods are fixedly connected to the tops of the crank one and the crank two. A pressure cylinder is hinged to the top of the hinge rod.

[0007] As a further scheme of the utility model: An oil cylinder is opened at the upper top of the cylinder cavity, and an inner sleeve is fixedly connected to the inner cavity of the oil cylinder.

[0008] As a further scheme of the utility model: A pressure cylinder is arranged in the inner cavity of the inner sleeve, and the pressure cylinder is in sliding connection with contact with the inner sleeve.

[0009] As a further scheme of the utility model: A is installed at the output end of the output rod.

[0010] As a further scheme of the utility model: A conduit is installed at the inner side of the upper surface of the cylinder cavity, and an oil inlet pipe is connected and installed on the outer wall of the conduit.

[0011] Compared with the prior art, the beneficial effect of the utility model is:

[0012] In this utility model, the inner sleeve moves downward in the pressure cylinder and pushes the hinged pressure cylinder and the hinge rod fixed to the pressure cylinder downward. Among them, the pressure cylinder and the inner sleeve are hinged, and the pressure cylinder pushes the hinge rod downward, causing the crank one and the crank two to rotate at the end of the output rod, and braking the output rod to rotate. Its structure is more optimized and the design is more reasonable. Description of the Drawings

[0013] Figure 1 It is a schematic structural diagram of a rotary valve for a diesel engine.

[0014] Figure 2 It is a cross-sectional view of a rotary valve for a diesel engine.

[0015] In the figure: engine 1, oil cylinder 2, cylinder chamber 3, fuel inlet pipe 4, conduit 5, side disc 6, through hole 7, output rod 8, crank one 9, pressure cylinder 10, inner sleeve 11, articulated rod 12, crank two 13. Specific implementation mode

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1 to 2 , in the embodiment of the present invention, a rotary valve for a diesel engine includes an engine 1. A side disc 6 is installed at one end of the engine 1. A through hole 7 is provided at the axial center of the end face of the side disc 6. On the upper part of the outer wall of the engine 1, cylinder chambers 3 are installed on both the left and right sides. A box cover is installed on the cylinder chamber 3. The output rod 8 is rotatably connected in the hole of the through hole 7. A crank one 9 and a crank two 13 are respectively installed at the end of the output rod 8. Articulated rods 12 are fixedly connected to the tops of the crank one 9 and the crank two 13. The tops of the articulated rods 12 are hinged to a pressure cylinder 10. An oil cylinder 2 is provided at the upper top of the cylinder chamber 3. An inner sleeve 11 is fixedly connected to the inner cavity of the oil cylinder 2. The pressure cylinder 10 is arranged in the inner cavity of the inner sleeve 11. The pressure cylinder 10 is in contact and sliding connection with the inner sleeve 11. An 14 is installed at the output end of the output rod 8. A conduit 5 is installed at the inner side of the upper surface of the cylinder chamber 3. A fuel inlet pipe 4 is connected and installed on the outer wall of the conduit 5.

[0018] The working principle of the present invention is:

[0019] When in use, the inner sleeve 11 moves downward in the pressure cylinder 10 and pushes the articulated pressure cylinder 10 and the articulated rod 12 fixed to the pressure cylinder 10 downward. Among them, the pressure cylinder 10 and the inner sleeve 11 are articulated. The pressure cylinder 10 pushes the articulated rod 12 downward, causing the crank one 9 and the crank two 13 to rotate at the end of the output rod 8, and braking the output rod 8 to rotate;

[0020] Among them, a positive included angle is formed at the connection part between the crank one 9 and the output rod 8, and a reverse included angle is formed at the connection part between the crank two 13 and the crank one 9. The two included angles have the same caliber to achieve the stable rotation of the driving rod.
