Glow plug with integrated pressure sensor and body thereof

A glow plug body (2), comprising:

• a glow plug head (10) at a first end;
• a fixing area having fixing means (12, 14) for fixing into a bore, said fixing means comprised of a threaded area (12), a sealing area (14), and a rigid area extending between the threaded area (12) and the sealing area (14);
• an elastically deformable part (18) between i) a connecting area (16) that is connected to the finger (4) and ii) the rigid area of the fixing area such that said connecting area (16) is mobile and movable longitudinally relative to the bore;
• and
• a pressure sensor (8) contained within the fixing area.

A glow plug, comprising:

• a tubular body (2) having at one end a glow plug head (10) and a fixing area having means (12, 14) for fixing into a bore;
• a finger (4) mounted on the body (2) of the glow plug at the end opposite the glow plug head (10);
• and
• a pressure sensor (8),
• wherein the finger (4) is fixed to the tubular body (2) so as to be fastened thereto in a connecting area (16),
• wherein the tubular body (2) has an elastically deformable part (18) between i) the connecting area (16) that is connected to the finger (4) and ii) the fixing area such that said connecting area (16) is mobile and movable longitudinally relative to the bore,
• wherein the pressure sensor (8) is disposed between an element (30) fastened to the connecting area (16) and a fixed element (20) of the glow plug, and
• wherein the pressure sensor (8) is contained within the fixing area of the tubular body (2).
