Pressure sensor for use in internal combustion engine |
摘要 |
A pressure sensor for use in an internal combustion engine includes a diaphragm member having a cylindrical part and a pressure receiving part which is subjected to an axial motion in an axial direction of the diaphragm member when a pressure in an external environment is applied to the pressure receiving part, a pressure detection member having pressure distributing parts and a piezoelectric part for generating a signal indicative of the applied pressure when it is stressed in response to the axial motion of the pressure receiving part, and a pressure transfer member for transferring the motion from the pressure receiving part to the pressure detection member, the pressure transfer member including a spherical member capable of rolling relative to the diaphragm member in a direction perpendicular to the axial direction of the diaphragm member at a position between the pressure receiving part and the pressure detection member.
