  • Pressure-measuring plug for a combustion engine
    Patent number: 9063031
    Abstract: Disclosed is a pressure-measuring plug for a combustion engine. The pressure-measuring plug comprises a plug body and a ring-shaped sensing structure. The plug body comprises an external thread for mounting the plug body into a cylinder head of the combustion engine. The ring-shaped sensing structure comprises an outer section and an inner core. A proximal end of the plug body is attached to the outer section. The inner core comprises a through hole for receiving a rod-shaped element. The ring-shaped sensing structure allows the inner core to move relatively to the outer section along a cylinder axis of the ring-shaped sensing structure. The inner core further comprises an internal thread for mounting in the through hole a rod-shaped element with an external thread.
