Abstract: A coolant equalizing reservoir for arrangement in a coolant circuit, having: a reservoir housing, a vortex chamber in the reservoir housing, a feed line for introducing coolant into the reservoir housing, and an outflow aperture for discharging coolant from the reservoir housing, where the feed line discharges into the vortex chamber, and wherein the vortex chamber is defined by a wall protruding from a base-wall section of the reservoir housing along a vortex chamber's axis, encircling the vortex chamber's axis in a closed manner, which in every direction orthogonal to the vortex chamber's axis is arranged at a distance from the reservoir housing.

Abstract: A coolant equalizing reservoir for arrangement in a coolant circuit, having: a reservoir housing, a degassing chamber in the reservoir housing, inside the former of which coolant flow along a curved degassing flow path, a feed line for introducing coolant into the reservoir housing, and an outflow opening for discharging coolant from the reservoir housing, where both the feed line and the outflow opening open into the degassing chamber, and where it is provided that the degassing chamber is configured as a flow duct proceeding along a curved duct path, where the duct path defines the degassing flow path.
