Abstract
The invention relates to a method and device for obtaining a determined flow resistance of a flow channel, especially an opening in a component. The method involves the following steps: a liquid flows through the flow channel; a characteristic depending on the flow resistance of the flow channel in the component is determined; and the flow channel is machined by means of a working method until said characteristic reaches a pre-determined nominal value.
Claims4
A device to machine a flow channel of a component and to achieve a determined flow resistance of a flow channel in said component, comprising a closed loop fluid system, a device for the generation of a fluid current within the fluid system, a fluid reservoir means for providing fluid to machine said flow channel, and a measuring bridge, wherein said component is a part of the measuring bridge for the determination of a parameter which is a function of the flow resistance of the flow channel in the component.
