Claim:
1. A dual flow fluid pressure pulse generator comprising: (a) a stator comprising a stator body with a circular opening therethrough: and (b) a rotor comprising a circular rotor body rotatably received in the circular opening of the stator body, wherein each one of the high flow fluid openings is fluidly coupled to a corresponding high flow curved depression on an external surface of the rotor body via a corresponding high flow channel in the external surface of the rotor body whereby the corresponding high flow curved depression is configured to direct fluid through the one high flow fluid opening, and each one of the low flow fluid openings is fluidly coupled to a corresponding low flow curved depression on an external surface of the rotor body via a corresponding low flow channel in the external surface of the rotor body whereby the corresponding low flow curved depression is configured to direct fluid through the one low flow fluid opening.
