Glow plug, particularly for operation in a combustion engine, comprising at least one heating rod () and at least one body () and at least one annular gap () between the heating rod () and the body () and at least one chamber () primarily arranged between the heating rod () and the body ().

Glow plug having coking-optimized design

The invention relates to a pencil-type glow plug, in particular for a self-igniting internal combustion engine. The plug includes at least one plug base with at least one essentially bar-shaped heating element, which projects on one end from the plug base, and at least one measurement element, the heating element and the measurement element being integrally bonded and/or force-locked and/or form-locked.

Pressure measuring glow plug

The invention relates to a device and a method for determining combustion chamber pressure, having at least one glow filament, at least one measuring element, at least two spring membranes, and at least one tubular base.

Device and method for determining combustion chamber pressure

A pressure glow plug for a diesel engine has a glow plug bodyfor being inserted into a cylinder of the diesel engine, a heating rodthat is arranged in the glow plug bodyand a pressure sensorthat is arranged between the heating rodand the glow plug bodyin such a way that the pressure in the combustion chamber of the cylinder that is transmitted by the heating rodinfluences the pressure sensor. The heating rodis arranged in the glow plug bodysuch that it can be displaced in an axially sliding fashion, namely by a corresponding sliding element, for example, a membraneor seals

Pressure glow plug for a diesel engine

A pressure-measuring glow plug for a diesel engine with a plug body () for insertion into a cylinder of the diesel engine, a heating rod () which is arranged in the plug body (), and a pressure sensor, which is arranged under an initial tension between the heating rod () and the plug body (), in such a way that the pressure sensor () is acted upon by the pressure prevailing in the combustion chamber of the cylinder. The heating rod () transmits the pressure in the combustion chamber of the cylinder to the pressure sensor () and is arranged so as to be displaceable in a sliding manner in the axial direction relative to the plug body (). A seal in the form of a bellows-shaped component () is provided between the heating rod () and the plug body ().

Pressure-measuring glow plug

A glow plug connector for a glow plug with built-in sensor, especially built-in pressure sensor, comprising a casing made of an electrically insulating material, which can be placed onto the glow plug. Provided centrally in the casing is a high-current connection which is connected to the high-current contact of the heating devices of the glow plug when the connector is placed thereon. Sensor contacts are provided on the casing insulated with respect to the high-current connection for contacting the sensor connections of the built-in sensor when the connector is placed thereon. For sealing an O-ring is provided on the outside of the casing whereas a locking mechanism serves to deliver the withdrawal force which must be overcome so that a coupling placed thereon can be removed from the glow plug connector. The connector is part of a system with a glow plug connector and glow plug.

Glow plug connector and system with a coupling, glow plug connector and glow plug

A pressure gauge glow plug for a diesel engine having a plug body, a heating element, and a pressure sensor, which is positioned under pretension between the heating element and the plug body in such a way that the pressure sensor experiences the pressure existing in the combustion chamber of the cylinder in which it is inserted. The heating element is positioned so that it may be slid in an axial direction in the plug body and transmits the pressure in the combustion chamber of the cylinder to the pressure sensor. The pressure sensor is positioned on a heating element support that is permanently bonded to the heating element in a cap that permanently bonded to the plug body. The heating element support and pressure sensor form a unit that has axial play in the interior of the cap.

Pressure gauge glow plug

A differential pressure switch having a piston which is guided in a piston housing in a cylinder bore against the force of a return element, the piston head having a pressure P applied to it, while a bore space around its tapered piston shaft has a pressure P applied to it. A switching process is triggered by movement of the piston, the piston tip acting on a switching element and being sealed in relation to the cylinder bore by a rolling diaphragm which is movable within the range of axial movement of the piston.
