Abstract
Providing a fluid pressure pulse generator having a fluid inlet chamber communicating with an accumulator via a movable ball positioned within the inlet chamber, a narrow fluid passageway bypassing the ball, an outlet chamber coupled to a valve seat for preventing communication between the outlet chamber and the accumulator when the movable ball assumes a first position against the valve seat and for permitting the outlet chamber to communicate with the accumulator when the ball is separated from the valve seat in a second position, introducing fluid within the fluid inlet chamber causing the ball to assume the first position and for causing the fluid to flow through the passageway into the accumulator until fluid pressure is very high; and thereafter rapidly reducing fluid pressure within the inlet chamber to cause the ball to assume the second position for in turn causing high impulse ejection of fluid from the accumulator into the outlet chamber.
