METHOD OF MAKING FLUID FLOW REGULATORS

摘要

A Method Of Making Fluid Flow Regulators The invention relates to a method of making a fluid flow regulator, in which an elastic ring acts in response to pressure against a profile core or an inner surface of a casing. It is possible with this method to perform matching of the regulators to a desired value quickly and without excessive waste. To this end the casting moulds for the profiled core or the inner surface are finish-machined in a certain way in dependence on the flow characteristic of the regulator. (Figs. 5A and B)
