ABSTRACT:
An impulse pump is disclosed. In one embodiment, the impulse pump utilizes an elongate tubular outer housing which surrounds an axial passage. The axial passage is lined with a tubular resilient member. The resilient lining fits snugly against the wall of the housing except at an encircling annulus in the housing. The annulus is isolated. It is filled with a fluid material which dissociates when exposed to high temperatures as will occur in the formation of an electrical spark. An electrical spark is formed in the annulus to increase the pressure in the annulus. When this occurs, it increases so much that a bulge is formed in the flexible lining, and the bulge ripples along the flexible lining as a source of compression pumping. The pressure in the lining exceeds the back pressure of the fluid to initiate the pumping action.
