ABSTRACT:
Fluid pulsation apparatus is disclosed which includes an elastomeric sleeve designed to expand circumferentially and longitudinally in response to internal fluid pressure. A fluid barrier in the form of a disk valve is located within the sleeve, and is biased closed by an expansion spring extending between the upstream end of the sleeve and the disk valve. A rigid housing surrounds the sleeve and restricts its circumferential expansion to a predetermined level. The apparatus can be made to produce either pulsing or continuous fluid flow by adjusting the flow rate of fluid downstream of the disk valve.
