Embodiment Construction
[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0033] Such as Figure 1 to Figure 9 As shown, a ship propeller includes a propulsion mechanism and a drive mechanism. It is characterized in that the propulsion mechanism includes a cylinder liner 2, a piston 4, a piston connecting rod 8 and an automatic opening device for a pressure limiting valve, and the piston 4 is set on the In the cylinder liner 2 , one end of the piston connecting rod 8 is hingedly connected to the piston 4 , and the other end is connected to the driving mechanism. The piston 4 is provided with a valve stem hole 22 and a vent hole 11 . A sliding sleeve is also arranged in the valve stem hole 22 .
[0034] The automatic opening device for the pressure-limiting valve includes a valve 3, a val...
