摘要： An underwater pulse jet motor comprises a stator and, within the stator, a rotor which has axially extending ducts at its periphery. The stator includes a closing segment which closes off the forward ends of the ducts successively as they pass it during rotation of the rotor. Gas under pressure is injected into the ducts through an injection passage formed in the stator in alignment with the closing segment, injection openings in the ducts coming successively into register with the injection passage for this purpose. In order to form a buffer of water in each duct between the closing segment and the injection opening, the opening is disposed downstream of the upstream end of the duct, and an efficient seal against the escape of the gas between the upstream ends of the ducts and the closing segment is thus achieved. The buffer water can be arranged to flow at a restricted rate downstream into the central passage to provide an ejector effect to increase the water flow through the central passage at low forward speeds of the motor.
