A pressure-measuring plug for a combustion engine

摘要

Disclosed is a pressure-measuring plug (100) for a combustion engine. The pressure-measuring plug comprises a plug body (102) and a ring-shaped sensing structure (104). The plug body comprises an external thread (102A) for mounting the plug body into a cylinder head of the combustion engine. The ring-shaped sensing structure comprises an outer section (104A) and an inner core (104B). A proximal end of the plug body is attached to the outer section. The inner core comprises a through hole (104C) for receiving a rod-shaped element (106). The ring-shaped sensing structure allows the inner core (104B) to move relatively to the outer section (104A) along a cylinder axis (105) of the ring-shaped sensing structure. The inner core (104B) further comprises an internal thread (104B1) for mounting in the through hole (104C) a rod-shaped element (106) with an external thread.
