Outflow quantity regulator, esp. for rain retention chamber - contains control chamber with float, independently operated choke apertures in compact construction

摘要

The outflow regulator contains a control chamber with an inlet and an outlet on the entry and exit side respectively and with associated choke apertures movably connected to a float in the chamber. The float (32) is connected to a control element (30) which moves vertically in the chamber (7,8) and has two control surfaces (33,34). Each control surface is movably coupled to one of the choke apertures (14,15). USE/ADVANTAGE - Esp. for use in controlling outflow from rain retention chambers. Regulator is of compact construction and yet enables mutually independent operation of choke apertures.
