摘要:
A glow plug (1), includes a pressure sensor (90), suitable for measuring the internal pressure of a motor cylinder in which the plug (1) is housed, a body (10) to be secured to the motor and a finger (20) in which a heater electrode is housed. The sensor (90) is firmly secured to the body (10) by the upper face thereof and rests on the finger (20), so that the pressure exerted on the finger (20) presses the sensor against the body (10).
摘要:
The invention concerns a glow plug comprising a glow plug body (2), a pressure sensor arranged inside the glow plug body (2), a threaded portion (6) on the outside of the glow plug body (2) and gripping means (12), generally of cylindrical form with a hexagonal section, enabling the body (2) to be gripped and screwed into a corresponding tapping, the gripping means (12) being made from synthetic material.

摘要:
The invention relates to a device which is used as a force-transmitting device (38′) for a pressure sensor (14) associated with a glow plug in an internal combustion engine and is embodied in the form of a tubular piece whose cross-section is substantially annular. The inventive device comprises an area (40) on which the external diameter thereof increases towards one end thereof. The front surface of the device corresponding to said flared end is embodied in the form of a bearing face receiving the piezo-electric pressure sensor. A glow plug integrating said force-transmitting device is also disclosed.
摘要:
This body (8) has on its outer surface both a screw thread (16) adapted for fixing the body (8) into a corresponding tapping in an engine (4), as well as a gripping zone (28), generally of cylindrical form with a hexagonal section, enabling gripping of the body (8) for screwing the glow plug (2) into the corresponding tapping. The outer diameter of the portion of the body between the thread (16) and the gripping zone (28) is throughout its entire height of a diameter at least equal to the outer diameter of the threaded portion (16). Application to internal combustion engines, in particular Diesel type engines.

摘要:
A glow plug includes a pressure sensor mounted within a tubular member (8) and held in the tubular member (8) by a bearing member. The bearing member is held in the tubular member (8) by plastic deformation (52) of the wall of the tubular member.
摘要:
The preheater plug (1) includes a tubular body inside which a pressure sensor (90) is mounted, the pressure sensor measuring the internal pressure of an engine cylinder wherein the plug (1) is arranged. The pressure sensor is provided with connection lugs extending in a substantially longitudinal manner in relation to the axis of the tubular body. The body (10) has a lateral groove in the inner lateral wall. At least one connection lug is engaged in the groove.
