Zusammenfassung:	The cooling device for a working machine (10) for the cooling of a heated fluid such as cooling and lubricating medium has at least one cooling unit (48) which by a pump unit with at least one hydraulic pump (P2) receives fluid filtered by a filter unit (40). A supply tank (38) is divided into a clean tank (22) and a dirty tank (36). The hydraulic pump feeds exclusively filtered fluid from the dirty tank into the clean tank, and an additional independent hydraulic pump (P5) transmits the fluid brought into the clean tank to the cooling unit for circulation.
