FIELD: engines and pumps.
SUBSTANCE: invention relates to an ignition plug for diesel engines, comprising a body (1), having outer thread (2), providing for the possibility of screwing the plug into the threaded hole of the diesel engine, a heating rod (3), installed sa capable of displacement in the body (1) in axial direction of the plug and protruding from it, a device (7) of pressure measurement, designed to measure pressure in a combustion chamber, acting at the heating rod (3), and a sealing membrane (5), arranged between the body (1) of the ignition plug and the heating rod (3). According to the proposed invention, between the body (1) of the ignition plug and the heating rod (3) there is a circular or a tubular damper (6) provided from perfluoro-elastomer used for suppression of radial oscillations of the heating rod (3). At the same time the damper (6) stretches around narrowing available on the heating rod (3).
EFFECT: reduced internal oscillations of an ignition plug with radial amplitude, convenience in shifting of a damper to a required position.
