Liquid separator and tank system comprising a liquid separator

A liquid separator for separating a liquid entrained by a gush-like gas flow, comprising:

• a housing formed by an upper housing portion and a lower housing portion, which, with regard to an alignment in an operating state, has an inlet opening at the lower housing portion and an outlet opening at the upper housing portion;
• a deflecting plate provided in the housing between the inlet opening and the outlet opening, the deflecting plate preventing the liquid entrained by the gas flow from exiting through the outlet opening in that the entrained liquid deflects onto the deflecting plate and is returned into the inlet opening due to gravity;
• wherein the housing and the deflecting plate are rotationally symmetric and the axis of symmetry is aligned substantially vertically during operation of the liquid separator;
• wherein the deflecting plate is fixed to the housing such that it is spaced apart from an inner wall of the housing to form an annular gap between the inner wall of the housing and the circumference of the deflecting plate through which the gas flow passes during operation of the liquid separator;
• wherein the upper housing portion and the lower housing portion each define conical elements having a large diameter portion and a small diameter portion, the housing being formed by connecting the large diameter portions of the upper housing portion and the lower housing portion and the inlet opening and the outlet opening being formed at the small diameter portion of the lower housing portion and the upper housing portion, respectively;
• and
• wherein the deflecting plate has the shape of a cone that is downwards inclined towards the large diameter portion of the upper and lower housing portions in an operating position of the liquid separator.
