摘要

The tank (10) has a housing providing a volume and a minimum bounding rectangle (80). A membrane divides the volume into two regions. A connecting ring (36) connects an outer diameter of the membrane with housing via the connecting ring. The housing and the connecting ring are designed and arranged such that the connecting ring lies within the minimum bounding rectangle in front, side and top views of the tank. The housing includes a rebound region (75), which is pulled back relative to a non-rebound region (76) of the housing in the front, side and top views.
