Abstract: An automotive solid-state headlamp includes a lamp body extending in a longitudinal direction, the lamp body having a rear base portion and a front portion and including a support member and a light-transmissive housing, a plurality of solid-state light sources arranged on the support member at the rear base portion of the lamp body, a drive circuitry electrically coupled to the light sources and arranged at the rear base portion of the lamp body and configured to operate the plurality of light sources when energized and reflector optics arranged at the front portion, wherein the solid-state light sources are configured to emit light towards the reflector optics, the reflector optics including a first reflector optic portion and a second reflector optic portion and wherein each of a plurality of first reflective surfaces disposed on the first reflector optic portion extend in an annular region around the longitudinal direction from the plurality of solid-state light sources towards the first reflector optic p

Abstract: In an embodiment an automotive solid-state headlamp includes a lamp body extending in a longitudinal direction, the lamp body having a rear base portion and a front portion and including a support member disposed in a light-transmissive housing, a plurality of solid-state light sources arranged on the support member at the rear base portion of the lamp body, and a drive circuitry electrically coupled to the light sources and arranged at the rear base portion of the lamp body and configured to operate the plurality of light sources when energized, wherein the plurality of light sources, when energized, are configured to cause the solid-state lamp to emit, through the light-transmissive housing (a) a luminous flux of at least 1500 lumens +/?10% when energized with a 13.2 Volt test voltage, or of at least 1750 lumens +/?10% when energized with a 28 Volt test voltage, or (b) a luminous flux of at least 1350 lumens +/?10% when energized with a 13.

Abstract: A multistage compressor may have at least one high-pressure stage and at least one low-pressure stage. The compressor may also include at least two pistons, which are driven via a common crankshaft supported in a crankcase, and which may be guided in associated cylinders, and which may form the at least one high-pressure stage and the at least one low-pressure stage. The compressor may further include a line arrangement which may communicate with the each of the cylinders for supplying and discharging air to and from the cylinders. There may be arranged in the line arrangement a switchable valve, which may be constructed in such a manner that the at least one high-pressure stage depending on a switching position of the valve may be associated with a different one of the cylinders.

Abstract: A method for producing a cylinder for a two-stroke engine, has the following steps: producing a casting core, wherein a central core slide for the cylinder chamber and at least one salt core for a transfer port are produced and the at least one salt core is connected to the central core slide, inserting the casting core into a casting mold, casting the cylinder in a die-casting process, removing the central core slide from the cylinder, wherein the at least one salt core is separated from the central core slide, and flushing the at least one salt core out of the cylinder. The invention further relates to a casting core for such a method.

Abstract: The invention relates to a method for producing a cylinder (10, 110) for a two-stroke engine, comprising the following steps: producing a casting core (30, 130), wherein a central core slide (31, 131) for the cylinder chamber (11, 111) and at least one salt core (33, 133) for an overflow channel (18, 19; 118, 119) are produced and the at least one salt core (33, 133) is connected to the central core slide (31, 131), inserting the casting core (30, 130) into a casting mold, casting the cylinder (10, 110) in a die-casting process, removing the central core slide (31, 131) from the cylinder (10, 110), wherein the at least one salt core (33, 133) is separated from the central core slide (31, 131), and flushing the at least one salt core (33, 133) out of the cylinder (10, 110). The invention further relates to a casting core (30, 130) for such a method.

Abstract: In order to provide a trailer coupling for motor vehicles comprising a bearing element, a towing element which can be pivoted in relation to the bearing element between an operative position and a rest position and displaced in the direction of the pivot axis between a pivoting position and a fixing position and a fixing device, with which the towing element can be fixed in position on the bearing element, with a simplified fixing of the towing element on the bearing element it is suggested that the towing element have a bearing member, that the bearing element have a receiving member, in which the bearing member engages at least in the fixing position and in relation to which the bearing member can be moved between the pivoting position and the fixing position in a direction of displacement and vice versa, and that the fixing device have a blocking device which blocks the bearing member with respect to any movement in the direction of displacement relative to the receiving member and has at least one blockin
