Abstract
A device for lubricating a machine comprises at least one pump or arranged in the oil circuit as well as a first oil tank for keeping a reserve of a first oil and a second oil tank for keeping a reserve of a second oil and temporarily storing an oil mixture. Oil lines are also provided between the oil tanks and the lubricating points. Furthermore, there is an oil sump for collecting the oil or oil mixture downstream of the lubricating points. Oil lines are provided between the oil sump and the two oil tanks. At least one first switching device is arranged in the oil lines, for opening or blocking the oil lines. Between the second oil tank and the first oil tank there is an oil line, which can be controlled by a second switching device. This device has the effect of improving the lubrication and extending the oil intervals.
