1. A valve unit, comprising:
an actuator;
a first valve;
a second valve; and
a rigid coupling,
wherein the first valve comprises a first valve housing and a first valve body that is rotatable about a first axis of rotation in the first valve housing,
wherein the second valve comprises a second valve housing and a second valve body that is rotatable about a second axis of rotation in the second valve housing,
wherein the first valve and the second valve are arranged coaxially to one another such that the first axis of rotation and the second axis of rotation coincide to form a common adjusting axis,
wherein the actuator is non-releasably coupled to the first valve body and releasably coupled to the second valve body through the first valve body,
wherein the first valve body in the first valve housing is rotatable with the actuator in a first direction of rotation rotating about the adjusting axis and into a second direction of rotation opposite to the first direction of rotation,
wherein the second valve body in the state coupled to the actuator is co-rotatable with the first valve body in the first direction of rotation and/or in the second direction of rotation and in the state decoupled from the actuator is not co-rotatable with the first valve body at least in the second direction of rotation, and
wherein the first valve body and the second valve body are connected to one another via the rigid coupling with a switchable freewheel such that the rigid coupling is only provided when the first valve body is rotated in a first direction and no rigid coupling is provided when the first valve body is rotated in an opposite direction of rotation.
