Pressurized water toy having a pressure actuated pulsator

A fluid pulsator, for introducing a pulsating pattern into a steady fluid flow stream, comprising:

• a) fluid inlet means;
• b) a reservoir, in fluid flow communication with said inlet means;
• c) expansible tubing in fluid flow communication with said reservoir;
• d) a sphere-shaped obturator, retained within said expansible chamber, for temporarily restricting fluid flow through said expansible chamber;
• e) a nozzle, in fluid flow communication with said expansible chamber, for imparting direction fluid flow into fluid flow outlet;
• f) biasing means for moving said sphere-shaped obturator from a blocking position, restricting fluid flow between said expansible tubing and said nozzle, to an unblocking position, permitting fluid flow between said expansible tubing and said nozzle;
• and
• g) means for actuating said pulsator for introducing a pulsating pattern into a steady fluid flow stream.

A method of providing a pulsating fluid stream, comprising the steps of:

• a) providing a continuous pressurized fluid stream;
• b) providing a length of expansible elastomeric tubing having and inlet and outlet;
• c) temporarily blocking fluid flow through said expansible tubing by providing an obturator, mountable within the length of expansible tubing;
• d) temporarily unblocking fluid flow through said expansible tubing by providing actuation means for temporarily actuating said obturator to unblock fluid flow through said expansible tubing;
• and
• e) biasing said obturator from a blocking to an unblocking position resulting in pulsating flow of fluid through outlet of said expansible tubing.
