Document Type and Number:
Japanese Patent JP5169951
Kind Code:

Abstract:
A stem is installed to an injector body and is resiliently deformable upon receiving a pressure of high pressure fuel conducted through a high pressure passage of the injector body. A strain gauge is installed to the stem to sense a strain generated in the stem. A molded IC device executes an amplifying operation, which amplifies a signal received from the strain gauge. A housing is installed to the stem and holds the molded IC device. The stem, the strain gauge the molded IC device and the housing are integrally assembled together to form a fuel pressure sensing unit, which is installed to the injector body by threadably fastening a threaded portion, which is formed at the housing, to the injector body.
