An oscillating spring valve fluid pumping system (10) for use in a flowing stream of fluid comprises a spring valve (20), check valve (180), and a housing with one inlet (96) and two outlets (66, 112), one outlet for each valve. As fluid enters the system, it is directed to the spring valve which is biased in the open position by a first spring. Fluid passing by the spring valve exits the housing through outlet (66) and returns to the stream. When a predetermined amount of pressure is reached, the spring valve closes thus creating a back pressure and redirecting the fluid through the check valve mechanism to relieve the pressure, for distribution to the user (124). Concurrently, the pressure at the spring valve is reduced, thereby causing the spring valve to open against a second spring. As fluid continues to enter the system, the spring valve repeatedly oscillates, thus producing intermittent increased pressure head at the system outlet. |
