Thermoresistive module, heating device comprising it, and its application to the heating of flow control devices for power supply installations of internal combustion engines.

摘要

The thermoresistive module (1 ') comprises a PTC thermistor (20') resiliently in abutment against a conductive body (16 ') by a conductive spring (23') connecting it to a supply terminal (25 '). The thermistor (20 ') is connected to the other supply terminal (26') by the body (16 '), a conductive backing plate (21') and a conductive spring (24 ') holding the plate ( 21 ') resiliently in abutment against the body (16') snapped with play on an insulating support (4 ') with a screen (10') insulating the two springs from one another. An electrical connector (3 ') is integrated into the support (4') provided with means (11 ', 12') for sealing on a member to be heated or whose temperature is to be measured. Application to the heating of the carburetor or throttle bodies of devices for controlling the feed rate of internal combustion engines.
