A pressure sensor for an internal combustion engine, which includes: a body containing a pressure-measuring membrane and a device for attaching to the cylinder head of the engine; and an end piece which extends substantially in an axial extension of the body, and includes a long part, and a substantially hemispherical convexity positioned on the end part of the long part.

Cavitation anti-resonance and anti-soot end piece for pressure sensor of an internal combustion engine

Disclosed is a sensor for measuring the pressure prevailing in a motor vehicle cylinder head, the sensor including a tubular body and an element sensitive to variations in the pressure, mounted in the tubular body. The sensitive element includes a tether including a fixing portion for fixing the tether to the tubular body, a tubular portion and a membrane fixed to the tubular portion at a connecting zone. The sensor is notable in that the connecting zone and the fixing zone are separated by a non-zero distance along the longitudinal axis and in that the tether includes, between the connecting zone and the fixing portion, a portion for absorbing a mechanical deformation.

Sensor for measuring the pressure prevailing in a motor vehicle cylinder head

A support () for an electronic module () for generating a signal, this module being intended to be inserted into a sensor () for measuring the pressure of the gases contained in a vehicle cylinder, the support () including a portion () for receiving the electronic module () and elements () for retaining the electronic module () on the receiving portion (), the electronic module () including a body (), the receiving portion () including elements () for attaching the retaining elements (), and the retaining elements () being configured to pivot between an open position (PO) in which the electronic module () can be placed on the receiving portion () and a closed position in which the retaining elements () are attached to the attachment elements () in order to retain the body () of the electronic module () on the support ().

Support for an electronic module of a pressure measurement sensor

A glow plug includes: a tubular body () having at one of its ends a plug head () as well as a zone for being fixed into a bore, an arm () mounted on the body () of the plug at the end opposite to the plug head (), and secured to the body () in a linking zone (), an elastically deformable portion (), located between the linking zone () with the arm () and the zone fixing the plug body (), such that the linking zone () is mobile and can move longitudinally relative to the so-called stationary fixing zone, and a pressure sensor () arranged between an element () secured to the linking zone () and a fixed element () of the plug.

Glow plug with integrated pressure sensor and body thereof

A glow plug including a tubular body with elements for fixing it into a bore, an intermediate tubular part arranged inside the tubular body, a finger disposed inside the intermediate tubular part with a heating electrode, and a pressure sensor connected to the intermediate tubular part, wherein a face of the sensor facing the finger is pressed thereto.

Glow plug provided with a pressure sensor

A glow plug includes a glow plug body (), a pressure sensor arranged inside the glow plug body (), a threaded portion () on the outside of the glow plug body () and gripping elements (), generally of cylindrical form with a hexagonal section, enabling the body () to be gripped and screwed into a corresponding tapping, the gripping elements () being made from synthetic material.

Head of a glow plug provided with a pressure sensor

This body () has on its outer surface both a screw thread () adapted for fixing the body () into a corresponding tapping in an engine (), as well as a gripping zone (), generally of cylindrical form with a hexagonal section, enabling gripping of the body () for screwing the glow plug () into the corresponding tapping. The outer diameter of the portion of the body between the thread () and the gripping zone () is throughout its entire height of a diameter at least equal to the outer diameter of the threaded portion (). Application to internal combustion engines, in particular Diesel type engines.

Body of a glow plug provided with a pressure sensor

A glow plug (), includes a pressure sensor (), suitable for measuring the internal pressure of a motor cylinder in which the plug () is housed, a body () to be secured to the motor and a finger () in which a heater electrode is housed. The sensor () is firmly secured to the body () by the upper face thereof and rests on the finger (), so that the pressure exerted on the finger () presses the sensor against the body ().

Glow plug comprising a pressure sensor and motor equipped therewith

The invention relates to a device which is used as a force-transmitting device (') for a pressure sensor () 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 () 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.
