Means for ascertaining the internal pressure in a pressure pipe system

摘要

A device for ascertaining the internal pressure in a pressure system, particularly in a fuel injection pipe system, wherein the pressure to be measured is contained within an element which includes at one point a wall portion of reduced thickness so as to act like a membrane, and wherein a sensor device is included which is positionable in engagement with the membrane-like wall portion to detect any elastic deformation and variation of the membrane caused by the influence of the internal pressure.
