摘要

A device includes a pressure sensor (11-13) for measuring pressures inside the combustion chamber of a cylinder in an internal combustion engine. The device includes: an outer body (1); a lug (5) extending partially into the combustion chamber; an inner housing (14) inserted into the body and surrounding an upper portion of the lug, the housing being secured to the lug and to the body and having an elastically deformable portion (17) between the two securing areas, characterised in that the housing (14) is secured to the body (1) at a securing area (18) extending in the upper portion of the body.
