Title: Pressure responsive flow directing device - has inner chamber with frusto=conical inlet plug which operates in response to pressure
Inventor: ALLESCH R
IPC: G01F7/00
Filed: 1977-01-19
Abstract: The valve for redirecting the flow of fluids according to pressure enables different meters to be used for high and low flow rates. At low pressure, fluid enters the inner chamber (17) of the valve from a tube (32) and passes to an outer chamber (18) through an opening (23) in a circular closing plate (20). It leaves the outer chamber by a narrow exit (14). At higher pressures, the entrance to the inner chamber (17) is widened by the upward movement of a frustoconical plug (31). At the same time the connection (23) between the inner and outer chambers is closed by the movement of a float (25). As a result the closing plate (20) rises, sealing the narrow exit (14) and opening a wider one (13). Hystersis is reduced by a damping device (28) connected to the central float (25).
