Described is a liquid heater having a housing, in which a flow channel runs from an inlet to an outlet, a heating resistor arranged within the housing for heating liquid flowing through the flow channel, control electronics which are arranged in an interior space of the housing, the interior space being sealed off from the flow channel, and a plug connector attached to the housing. Provided according to this disclosure, the plug connector has a vent duct which is closed by a membrane and which leads to the interior space sealed against the ingress of liquid, in which interior space the control electronics are arranged.

A corona ignition device is described, with a central electrode, an insulator, in which the central electrode sits, a coil, which is connected to the central electrode, a metal housing, which holds the insulator and surrounds the coil, and a cover, which closes the metal housing at its end facing away from the insulator. According to this disclosure, provision is made for a spring arranged between the cover and the coil. In another aspect, a shield is provided that surrounds the housing and comprises several shell elements which each surround a section of the circumference of the coil.

Corona ignition device

This disclosure relates to a corona ignition device having a coil, which has an elongate coil body and a coil winding wound onto the coil body, an ignition electrode connected to the coil, and an insulator, inside which the ignition electrode is situated. According to the present disclosure, the coil body has a hollow section.

Described is a glow plug with a glow pencil that comprises a forward end with a glow tip and a rearward end, a housing in which the rearward end of the glow pencil is arranged and in relation to which the glow pencil is movable in its longitudinal direction, and a bellows that is connected to the housing and the glow pencil. According to this disclosure, it is provided that a forward end of the bellows is attached to the housing and a rearward end of the bellows is attached to the glow pencil.

Glow plug

This disclosure relates to a glow plug connector for a sensor glow plug, comprising a housing made of plastic, a plurality of contact elements made of metal, which form contact surfaces bearing against a circumferential wall of the housing, wherein the contact elements protrude on the glow-plug side from a base of the housing. The contact surfaces are embodied as segments of a circle that protrude from a strip-shaped section of the contact elements. This disclosure also relates to a connector for a cylinder pressure sensor for measuring the pressure in a combustion chamber of an internal combustion engine.

The invention relates to a pressure gauge for measuring the pressure in a combustion chamber of an engine, comprising a housing, a tappet, which is movable in the housing in an axial direction under the action of combustion chamber pressure, a sensor for detecting an axial displacement of the tappet, and a force transmitter, in order to transmit a force loading the tappet to the sensor. In accordance with the invention, the force transmitter has at least one damping section for damping flexural vibrations, at which its flexural rigidity is reduced.

Pressure gauge

A combustion chamber pressure gauge for an internal combustion engine, comprising a housing tube, a plunger, which is movable in an axial direction in the housing tube under the effect of combustion chamber pressure against a restoring force, and comprising a seal, which is disposed between the plunger and the housing tube, and comprising a sensor for detecting an axial displacement of the plunger. The sensor is decoupled from thermally induced expansions or contractions of the housing tube, in that the sensor is attached to a carrier, which is suspended in the housing tube, and the plunger is movable relative to the carrier under the effect of combustion chamber pressure.

Combustion chamber pressure gauge

A pressure measuring device includes a housing and a rod which is movable in the axial direction in the housing under the effect of combustion chamber pressure where the rod protrudes from the housing. A sensor measure combustion chamber pressure acting on the rod, and a first diaphragm is attached to the housing through which the rod extends. A second diaphragm is attached to the housing through with the rod extends between the sensor and the first diaphragm. The second diaphragm generates a return force when the rod undergoes axial displacement caused by pressure on the rod.

Dual diaphragm combustion pressure measuring device

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 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

The invention relates to a glow plug for Diesel engines, comprising a housing, a heater rod, which is movable in the housing in axial direction and projects from the housing at a forward end, and a pressure measuring device for measuring a combustion chamber pressure exerted on the heater rod. It is provided according to the invention that a housing chamber is filled with a substance having or achieving liquid to paste-like consistency at temperatures occurring during operation and conducting heat generated by the heater rod to the housing.
