FIELD: engines.
SUBSTANCE: disclosed is thermostatic recirculation valve (TRV) 20, which provides effective heating of fuel module 22 during operation under low temperatures to prevent fuel waxing or its conversion into gel. TRV 20 provides control over heated fuel flow returned into module 22 via channel 40. Control depends on fuel temperature in channel 13 at module output, wherein returned fuel does not contact directly with paraffin element 54. Paraffin element 54 is isolated from direct contact with returned fuel with higher temperature due to elastomer seal 56 application, which prevents direct contact of returned fuel and paraffin element. Moreover, paraffin element is located in module outlet channel 13.
EFFECT: invention can be used in fuel injection systems of internal combustion engines (ICE).
