The utility model discloses a positive mud pulse generator which comprises a plunger pump arranged in an outer barrel of a pulser, a plunger, a swash plate of the plunger pump, a magnetic axis, a main valve, a end plug and a socket. The utility model is characterized in that the utility model also comprises an electric generator, and rotors with magnets of the electric generator are connected with one end of the magnetic axis approaching the main valve. Coils of the electric generator are fixed on the end plug. The coils and the rotors of the electric generator are arranged in an interval way, and the coils are electrically connected with the socket. The positive mud pulse generator with a turbine generator of the utility model can supply power for an electromagnetic valve thereof and underside instruments without batteries. As a consequence, the utility model supplies convenience for operation and use, besides, the power supply voltage is stabler. Further, the positive mud pulse generator can generate larger push force through the design of a sucking-in oil circuit of the plunger of a pump body and the inclined angle of the swash plate. The utility model is suitable for the operation in deep wells. Besides, the utility model avoids the end head of the swash plate scratching.
