  • Method for producing fluid flow regulators
    Patent number: 4632791
    Abstract: The invention relates to a method of making a fluid flow regulator, in which an elastic ring acts in response to pressure against a profiled 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.
