Coolant device for cooling drive train of commercial vehicle, has operating medium pump supplying operating medium from supplementary container into operating medium storage, where operating medium pump is passively formed

摘要

The device has an operating medium storage (10) for provision of a compensating volume in a cooling circuit (14). A supplementary container (11) fills the cooling circuit and an operating medium pump (12) with the operating medium. The operating medium pump in an operating mode supplies the operating medium from the supplementary container into the operating medium storage, where the operating medium pump is passively formed. The operating medium pump is designed as a jet pump. A valve unit (13) increases operating medium pressure in the operating medium storage.
