摘要： A filter housing has a pot-like base, a lid that closes the base in a pressure-tight manner, one or several additional elements such as pipes, flanges or the like, which are connected to the wall of the base in the area of the seal between base and lid, and at least one rib which extends radially around the base in this area. The rib has varying dimensions around the circumference of the base and a reduced cross-section in the area in which the additional elements are connected to a wall of the base. The lid and base are directly screwed together by means of matching threads and the variable cross-section of the rib ensures a practically identical rigidity of the base against inner pressure stresses all around its circumference.
