Abstract: A valve assembly for controlling cooling fluid in a vehicle including: a valve housing having a housing body and a cover connected to the housing body, a valve body receiving space in the valve housing, which is enclosed by the housing body and the cover, a fluid line system having fluid lines, which run in different spatial regions starting from the valve body receiving space, a valve body accommodated in the valve body receiving space rotatable about an axis, the valve body tapering along the axis such that by rotating the valve body about the axis, a fluid connection situation of at least two fluid lines of the fluid line system is changeable, and a prestressing means, which applies a pressure onto the valve body along the axis in the tapering direction, the valve body and the housing body formed as injection molded parts from thermoplastic.

Abstract: A valve assembly for controlling cooling fluid flows in a motor vehicle, the valve assembly including: a valve housing having a main housing body and a housing cover connected to the main housing body, a valve body receiving space being developed in the valve housing, which is enclosed by the main housing body and the housing cover, a fluid line system having at least two fluid lines, which run in different spatial regions starting from the valve body receiving space, a valve body, which is accommodated in the valve body receiving space rotatable about an actuation axis, the valve body being designed to taper along the actuation axis in such a way that by rotating the valve body about the actuation axis, a fluid connection situation of at least two fluid lines of the fluid line system is changeable, and a prestressing means, which applies a pressure onto the valve body along the actuation axis in the tapering direction, both the valve body as well at least the main housing body to be formed as injection m
