Suction module for IC engine

摘要

The module has a suction section with two suction channels (12), each with a closure element to alter its flow profile. At least two closure elements are operated by a common actuator via couplings. The couplings have an elastic section for tolerance compensation between closure elements and actuators. An elastic joint may be located between actuator, coupling, and/or closure element. The closure elements are flaps, especially mainly round flaps (13), turning about a shaft (14). The flaps are connected preferably via articulated levers (16) and ball bearings (28) to the couplings respective connectors. All flaps occupy mainly the same position, e.g. open or closed, which are defined by stops.
