Automobile coolant liquid degasser unit

The invention relates to a passive motor vehicle coolant liquid degasser unit (30) for degassing a circulating coolant liquid of a coolant circuit of a motor vehicle, having a degasser housing (32) which defines a deceleration chamber (40, 40 ') having a chamber liquid inlet (38, 38') and a chamber liquid outlet (39, 39 '), and the degasser housing is provided with a degassing opening (50) at the vertical top of the deceleration chamber (40, 40 '). The fluid cross-section of the deceleration chamber (40, 40 ') is continuously increasing between the chamber liquid inlet (38, 38') and the chamber liquid outlet (39, 39 '). 本发明涉及一种用于对汽车的冷却剂回路的循环冷却剂液体进行除气的被动式汽车冷却剂液体除气器单元(30)，该被动式汽车冷却剂液体除气器单元具有除气器壳体(32)，该除气器壳体限定出具有室液体入口(38、38')和室液体出口(39、39')的减速室(40、40')，并且该除气器壳体在减速室(40、40')的竖向顶部处设置有除气开口(50)。减速室(40、40')的流体横截面在室液体入口(38、38')与室液体出口(39、39')之间是连续增大的。
