ABSTRACT:
In a fluid-flow pulsator, a housing has a chamber with an inlet and an outlet. Within the housing is a piston assembly having first and second pistons with the first having a working area less than that of the second. A valve associated with the assembly closes the outlet on movement of the assembly. The assembly is resiliently urged in a direction effecting closure of the outlet with the first and second pistons effectively being disposed in the chamber on opposite sides of the inlet. The introduced fluid pressure, the urging strength and the piston areas are correlated so as to produce pulses of fluid from the outlet in response to a supply of fluid to the inlet.
