Injector cooling arrangement for motor vehicle, has springs overlapped with each other and interposed between nozzle and wall of section for permitting transmission, by conduction, of heat accumulated in nozzle to heat engine element

摘要

#CMT# #/CMT# The arrangement (10) has an axial housing (12) with a tubular section (18) receiving a cylindrical body (20) of an axial injector (16) such that a part of the body is in contact with the section. The housing has another section (22) for receiving a cylindrical nozzle (24) e.g. nose, of the injector. A cooling unit allows the cooling of the injector. Internal and external coil springs (26, 28) overlap with each other and are interposed between the nozzle and a wall (30) of the section (22) to permit transmission, by conduction, of heat accumulated in the nozzle to a heat engine element (14). #CMT#USE : #/CMT# Arrangement for cooling an injector in a housing of a heat engine element e.g. cylinder head or exhaust line, of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The springs are overlapped with each other and are interposed between the nozzle and the wall of the section for permitting the transmission, by conduction, of the heat accumulated in the nozzle to the heat engine element, thus improving the cooling of the nozzle of the injector. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of an injector cooling arrangement. 10 : Injector cooling arrangement 12 : Axial housing 14 : Heat engine element 16 : Axial injector 18 : Tubular section 20 : Cylindrical body 22 : Section 24 : Cylindrical nozzle 26, 28 : Internal and external coil springs 30 : Wall.
