Abstract: A motor vehicle lighting device has a housing and a ventilating device with an air supply line, which has an air intake opening, and which tapers away from the air intake opening in the form of a funnel, and which has an air outlet opening. The ventilating device includes a water collecting chamber, into which the air supply line opens with a transition cross section, and which has a water discharge opening and an air outlet opening, wherein the water discharge opening is disposed lower than the air outlet opening in an intended use of the ventilating device in a motor vehicle. A clearance of the water collecting chamber lying between the transition cross section and the air outlet opening is greater than the transition cross section.

Abstract: A headlight for a motor vehicle having a headlight housing with a light module arranged therein for producing a desired light distribution, wherein the headlight housing comprises an air-inlet opening and an air-outlet opening for air to flow through the headlight housing.

Abstract: A machine tool having a machine frame and a workpiece table. It is provided that the workpiece table (5), on one of its sides (14), is held on the machine frame (2) by a holding device (4), the holding device (4) having at least two holding elements (6, 7), which are spaced apart from one another on the said side (14) of the workpiece table (5) and which are disposed at differing height positions (9, 10), such that an upper and a lower holding element (6, 7) is realized, and at least one of the holding elements (6, 7) being equipped with at least one piezo actuator (24) for altering its length and, associated therewith, influencing the position of the workpiece table.
