description Method and apparatus for generating fluid pulses in a fluid column, such as within a downhole well, are disclosed. A described example fluid pulse generator utilizes a moveable flow conduit through which at least a portion of a downwardly flowing fluid column will pass. The moveable flow conduit can be moved, such as by pivoting, in and out of registry with other components defining the fluid flow path to provide resistance to flow of a selected duration and pattern, and thereby to generate pressure pulses within the fluid column detectable at the surface. In some examples, magnetic actuators will be used to perform the described pivoting of the moveable flow conduit.
