摘要:
Valve devices for internal combustion engines are known which comprise a housing (2) with at least one inlet (4, 6) and one outlet (8) formed therein, at least one passage opening (10, 12) via which the at least one inlet (4, 6) can be fluidically connected to the at least one outlet (8), at least one valve-closing member (18, 20) by means of which the passage opening (10, 12) can be controlled, a valve rod (22) which can be translationally moved by means of an actuator (56) and on which the at least one valve-closing member (18, 20) is arranged, a spring (32) that surrounds the valve rod (22) and is supported with its first end against the one valve-closing member (18) and with its opposite end against a stop element (20), and an element that substantially surrounds said spring (32). The functionality of these devices is often limited owing to high thermal loads and high sensitivity to particles of dirt. It is therefore suggested that said element should be substantially formed from two radially closed peripheral surfaces (46, 48) that are in mutual engagement, the first peripheral surface (46) lying against the at least one valve-closing member (18) and being able to be moved therewith, and the second lying against the stop element (20), said valve-closing member (18) being moveable relative to said stop element (20).
