  • Built-in amplifier-type combustion pressure sensor and manufacturing method thereof
    Patent number: 5402683
    Abstract: A built-in amplifier type combustion pressure sensor which can be assembled by simplified operation. A pressure detecting device is fixed to one end of a housing with leads extending inside the housing. The leads are bent in a predetermined form by inserting a spacer and a cover from an opening of the housing located on the opposite side of the pressure detecting device. An amplifier circuit board is inserted into the housing from the opening so that the leads are inserted into holes provided on the amplifier circuit board and protrude from the surface of the amplifier circuit board facing the opening side. The protruding end of each lead is connected to the amplifier circuit board.

  • Pressure sensor for use in internal combustion engine
    Patent number: 5168192
    Abstract: 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.
