Abstract

A device for lubricating and cooling gear mechanisms has a supply line for supplying lubricating and coolant oil from an oil sump into a first channel in a spray pipe. The first spray channel connects to at least one first nozzle for the targeted spraying of the lubricating and coolant oil into areas of the gear that require extensive lubrication and that are allocated to the first channel. The supply line is connected to a second channel and one or more second nozzles connected to the latter for spraying the oil in areas that require extensive lubrication and are allocated to the second channel. The channels are prioritized with regard to more or less critical regions of the gear mechanism. A control valve that is responsive to a back-pressure in the spray pipe actuates the channels to supply the gear mechanism in accordance with the prioritization of the regions.
