Abstract
An elastic pipe piece, which is arranged between the air filter and a throttle housing in the air intake section, in proximity of both ends, has one bellows respectively pointing to the outside. The bellows compensate tolerances and have a vibration-disconnecting effect. Two pipe sockets are contructed integrally with the pipe piece, a crankcase ventilating system or an idling adjuster being connected to these pipe sockets. In addition, in proximity of an accommodating means, a clamping fork is constructed integrally with the pipe piece, which accommodates the idling adjuster and fixes it in position.
Claims8
An air intake section of an internal combustion engine comprising:
- an elastic pipe piece means arranged between an air filter and a throttle housing;
- ring-shaped elastic bellows means, which are curved towards an outside of the pipe piece means, positioned adjacent ends of the pipe piece means, the bellow means having a wall thickness less than a wall thickness of the pipe piece means;
- pipe socket means for connecting air-carrying pipes to the pipe piece means and
- clamping fork means for connecting a component to the pipe piece means.
