Abstract

PURPOSE: To facilitate assembling and composition and stabilize the operation by providing a closely wound spring on the passage between a vortex pump and a pressure tank such that the passage is opened with the elongation of the spring caused by the pump discharge pressure.
CONSTITUTION: When the jet pumping is started, the inner pressure in the casing 3 is increased. As a result, a closely wound spring 8 provided on the passage between the pump and a pressure tank is urged and elongated to form gaps between adjacent turns, thus permitting water supply to an outlet 7. If the spring 8 is closely wound such that it will not be elongated until a constant pressure is applied, no gaps between adjacent turns are formed until the inner pressure of the casing 3 exceeds a predetermined pressure, and in the initial stage of operation the pressure in the casing 3 is reduced via the outlet 7. In this way, it is possible to solve such problems as sequiring long time for the jet driving. In addition, since the spring 8 is made of a single wire closely wound in a conical form and is provided at the top with a flange 12 as one body, it can be very conveniently mounted in the water passage such as the outlet 7 and can also be inexpensively manufactured.
