Abstract

A shaft-bearing bush assembly for a valve arrangement for an air-conditioning system is disclosed. The shaft-bearing bush assembly includes a shaft drive-connectable to a valve of the valve arrangement and a bearing bush, in which the shaft is rotatably received relative to the bearing bush between a first rotary position and a second rotary position about an axis of rotation extending along the axial direction. A bush projection is non-rotatably arranged on the bearing bush relative to the bearing bush and a shaft projection is non-rotatably arranged on the shaft relative to the shaft. The bush projection and the shaft projection are matched to one another such that the bush projection provides a rotary stop for the shaft projection for limiting the rotary movement of the shaft between the first rotary position and the second rotary position.
