An exhaust gate, in particular for a heavy-goods vehicle, has a housing, which has an inlet and first and second outlets, on which first and second valve seats are formed, and a valve flap, which can be pivoted between the two valve seats to close the first or second outlet. The housing is formed as a cast part, which connects the inlet and at least the first outlet integrally to each other. The valve flap has a larger cross section than the inlet and the first and second valve seats.

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.

Method and device for lubricating a machine especially an internal combustion engine

In a piston/liner arrangement for a reciprocating-piston internal combustion engine, wherein a piston with a skirt is axially movable in the liner, at least one of the piston skirt and the liner includes sections with an open-pore surface structure in which a lubricant with a high affinity to the material having the open-pore surfaces structure is disposed so as to form a lifetime lubrication arrangement.
