Abstract
An adjustable two-way valve device is described that is embodied as a rotary valve. According to the invention the use of the rotary valve as a two-way valve is achieved by the skillful arrangement of passage openings of a valve plate with respect to control openings of a valve element. Thus it is possible to control mass or mixed flows independently of or dependent on one another with only one valve element. In particular a use in the field of exhaust gas recirculation with a bypass line and an exhaust gas cooler is advantageous, since mixed flows and thus temperatures can be run.

An adjustable two-way valve device for a combustion engine, comprising:
- a first outlet or inlet channel;
- a second outlet or inlet channel;
- a valve plate having a first passage opening of the first outlet or inlet channel and a second passage opening of the second outlet or inlet channel;
- a third outlet or inlet channel;
- and
- a rotary valve element having at least one control opening corresponding to one or both of the passage openings of the first and second outlet or inlet channels;
- wherein the valve element is disposed to controllably open or close fluid connections between the third outlet or inlet channel and one or both of the first and/or the second outlet or inlet channels, so that the openings corresponding to the first outlet or inlet channel and the second outlet or inlet channel are made independently of one another or dependent on one another.
