Abstract
A pressure regulating device for high pressure fuel systems includes a pressure sensing element attached directly to a pressure chamber. The pressure sensing element includes a semiconductor element that deflects in response to a deflection of a portion of the pressure caused by fuel pressure within the pressure chamber. A coil is electrically connected with the pressure sensing element and is configured to generate a magnetic field that moves a magnetic armature to control fuel pressure.
