Cylinder head for motor vehicle, has tube maintained in stop against surface of cylinder head using sleeve with lower end that is support on upper end of tube, where sleeve is fretted in cylindrical face of bore

摘要

#CMT# #/CMT# The cylinder head (1) has a coaxial injector tube (4), which is received in a bore (2), where the tube crosses a liquid circulation cavity (24) of the cylinder head. The tube is maintained in stop against surface of the cylinder head using a sleeve (5) fixed to the cylinder head. The sleeve is fretted in a cylindrical face (22) of the bore, and a lower end of the sleeve is in support on an upper end (42) of the tube. #CMT#USE : #/CMT# Cylinder head for a direct injection type heat engine and an internal combustion engine of a motor vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The lower end of the sleeve is in support on the upper end of the tube, thus permitting the sleeve to be mounted in an easy manner at reduced cost. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of a cylinder head for an engine. 1 : Cylinder head 2 : Bore 4 : Coaxial injector tube 5 : Sleeve 22 : Cylindrical face 24 : Liquid circulation cavity 42 : Upper end.
