| Abstract: | The mounting of a component subjected to pressure from a fluid requires special precautions if the component is made of wear resistant, hard and hence generally brittle material and may be destroyed by locally raised stresses. A fluidic component of this kind, made, for example, of silicon/glass is arranged in an elastomeric shaped component, made, for example, of silicon rubber. The inner contours of the elastomeric shaped component correspond to the outer contours of the fluidic component. The outer contours of the shaped component corresponds to the inner contours of a holder. Due to this “floating mounting” there are no unacceptable local pressure peaks and no deformation of the fluidic component. The device is particularly suitable for mounting a fluidic component made of glass or silicon, or miniature dimensions, subject to high pressure. |
