Abstract (en)

[origin: WO2015078545A1] The invention relates to a cylinder head (10, 50, 90, 130) for an air compressor, having at least one intake duct (12, 52, 92, 132) for the intake of non-compressed air from the surroundings, and having at least one pressure duct for discharging the compressed air, and also having a cooling water duct (14, 16, 54, 56, 94, 96, 136), wherein the at least one intake duct (12, 52, 92, 132) can be closed off in pressure-tight fashion with respect to a compression chamber (22, 62, 102, 142) by means of at least one intake lamella (20, 60, 100, 140) arranged on an underside (18, 58, 98, 138) of the cylinder head. It is provided according to the invention that the at least one intake duct (12, 52, 92, 132) is surrounded in sections by a substantially concentric annular groove (26, 66, 106, 146) which is close to the intake lamella. In this way, heating of the air flowing out of the surroundings into the cylinder head (10, 50, 90, 130) via the at least one intake duct (12, 52, 92, 132) is advantageously reduced.
