Abstract

A flow regulator for controlling the flow of fluid, particularly water, to compensate for changes in pressure. The regulator comprises a fitting having an elastically-deformable membrane providing flow passages through the fitting. Pressure variations deform the membrane to modify the flow area of said passages to automatically compensate for the changes in pressure and thereby reduce or eliminate pressure waves arising in the pipe. The membrane comprises a disc-like base, the downstream surface of which is provided with spacer means leaving a star-like pattern of radial passages for medium flow having their outer ends open upstream for admission of fluid to said passages, the size of which is to be reduced by elastic deformation of said base and said spacer means in response to changes in the pressure in the flow.
