    • Disclosed is the structure of a glow plug with a combustion pressure sensor which includes a heater unit which is reduced in diameter stepwise. In the structure, the area of a member connecting the heater unit to a housing is made sufficiently large, so that the detection accuracy of the pressure sensor is improved. The structure can further improve the detection accuracy of the pressure sensor. The glow plug 100 includes a substantially cylindrical housing extending in an axial direction; a rod-shaped heater unit that has a front end protruding from the front end of the housing and is movable in the axial direction; a connecting member that connects the heater unit to the housing within the housing and allows the heater unit to move in the axial direction; and a pressure sensor that detects pressure received by the heater unit. The heater unit has a large-diameter portion formed at the rear end thereof and a small-diameter portion formed frontward of the large-diameter portion and having a diameter smaller than the diameter of the large-diameter portion. The connecting member connects the small-diameter portion of the heater unit to the housing within the housing.
    • 公开了具有燃烧压力传感器的电热塞的结构,其包括阶梯式缩小的加热器单元。 在该结构中,将加热器单元连接到壳体的构件的面积足够大,从而提高了压力传感器的检测精度。 该结构可以进一步提高压力传感器的检测精度。 电热塞100包括沿轴向方向延伸的大致圆柱形的壳体; 棒状的加热器单元,其具有从壳体的前端突出的前端并且可沿轴向移动; 连接构件,其将所述加热器单元连接到所述壳体内的所述壳体并且允许所述加热器单元在所述轴向方向上移动; 以及检测由加热器单元接收的压力的压力传感器。 加热器单元具有在其后端形成的大直径部分和在大直径部分的前面形成并具有比大直径部分的直径小的直径的小直径部分。 连接构件将加热器单元的小直径部分连接到壳体内的壳体。
