ABSTRACT:
An injection valve to control the fuel injection into the intake duct of an internal combustion engine. The injection valve, which is preferably mechanically actuated, is placed in a supporting opening in the wall of an intake duct, and is provided with a gasket between the outer wall of the injection valve housing and the outer wall of the support. The injection valve housing is arranged contact-free in the support opening and the thus-produced annular slit is closed by a bellows member. The injection valve housing is associated at its free end with a fuel distributor element. In this manner a greater freedom of movement of the valve housing in the support opening is thereby provided in addition to a substantial increase in thermal insulation, whereby manufacturing tolerances and thermal fluctuations are not significant.
