Abstract
A generator for cyclically moving jets comprises a housing including a chamber having a circular track therein, a body disposed in the chamber and rollable along the circular track, a hollow revolvable axle coupled to the body and extending to outside of the chamber and rotatably born in and sealed to the housing, a nozzle attached to the axle outside of the chamber for issuing at least one jet misalignedly in relation to the axis of rotation of the axle, and a fluid flow supply leading to an upstream region of the chamber. In operation, fluid flows past the body, through the hollow revolvable axle and issues from the nozzle as a jet. The body rolls along the circular track as a consequence of fluid-dynamic forces acting on the body. A fountain employs the generator for dynamic display of the cyclically moving jets issuing therefrom.
