A pressure measuring glow plug includes: a housing in which a heating pin for igniting a combustion mixture of an internal combustion engine and a pressure measuring unit for recording a combustion chamber pressure of the internal combustion engine are situated. The heating pin has a glow current contact for an electric heating element. At the end of the heating pin facing away from the combustion chamber, a pressure transmitting element is fastened, which transmits the combustion chamber pressure acting on the heating pin to the pressure measuring unit. The pressure transmitting element is sleeve-shaped and forms an accommodation space for the glow current contact of the heating element.

A pressure-measuring device for recording a pressure in a combustion chamber of an internal combustion engine, having a force transmission body, situated in a housing, which is exposed to the combustion chamber and which transmits the combustion chamber pressure to a pressure-measuring unit at least indirectly by an axial motion, and having a flexible diaphragm, which is situated between the force transmission body and the housing. The flexible diaphragm is configured to be resilient to implement the axial motion of the force transmission body within the housing. A flexible additional diaphragm is connected ahead of the flexible diaphragm on the combustion chamber side, which seals the flexible diaphragm from the combustion chamber.

The invention relates to an electrical machine, preferably an alternator ( ) for motor vehicles, comprising a rectifier assembly ( ) that is fixed to an end shield ( ) of the machine. Said rectifier assembly is cooled by a fan ( ) that operates in the end shield ( ), the diodes being positioned on a negative connecting plate ( ) and a positive connecting plate ( ) of the rectifier assembly ( ). The aim of the invention is to evacuate the dissipated heat from the rectifier assembly ( ) in an advantageous manner. To achieve this, the rectifier assembly is located in an opening in the front face ( ) of the end shield ( ) and is connected in an electrically and thermally conductive manner by one of its two connecting plates ( and ) to a cooling body ( ), which is connected to the exterior of the end shield ( ) and covers the opening ( ). The cooling air that is thus taken in by the fan ( ) first flows from the exterior across the cooling body ( ) in a radial manner towards the interior, entering the machine in the vicinity of the shaft through orifices ( ) in the end shield ( ) and from here, having reached the fan ( ), subsequently flows past the other connecting plate ( and ) in a radial manner towards the exterior.
