Separator device for separating a fluid, in particular a lubricant, from a coolant

A separator device for deposition of a lubricant from a coolant fluid comprising:

• a separator cylinder having an inlet region with at least one inlet for the coolant fluid and an outlet region for the deposited lubricant, the inlet region spaced apart from the outlet region in an axial direction of the separator cylinder;
• a separation tube configured and arranged coaxially in the separator cylinder, the separation tube extending at least over the inlet region such that the separation tube is spaced apart from the separator cylinder in a radial direction in the inlet region;
• and
• a spring-loaded closure configured and arranged in the inlet region to automatically regulate a flow velocity of a volume flow of the coolant fluid flowing through the at least one inlet, the spring-loaded closure configured as a bent leaf spring having a radius of curvature smaller than half an inner diameter of the separator cylinder.
