The invention relates to an air compressor having a catalyst that is disposed in a reception block. The reception block is interposed between a valve block and a cylinder cover, comprises an inlet port in the region of a valve block outlet port, and an outlet port in the region of a cylinder head inlet port, so the compressed air exiting the valve block outlet port flows through said catalyst and through the outlet port into the cylinder cover.

A compressed-air compressor for producing compressed air for a compressed-air system of a vehicle includes a cylinder and a piston. The piston is arranged in the cylinder and divides the interior space of the cylinder into a compression chamber, which can be connected to the compressed-air system of the vehicle for the purpose of conveying compressed air, and a neutral chamber. The neutral chamber is charged with an auxiliary pressure such that the pressure in the neutral chamber is temporally on average higher than atmospheric pressure. The compressed air production by means of the piston/cylinder-type compressed-air compressor is improved such that the maximum value of the torque to be imparted for driving the compressor is reduced.

A compressor system for a compressed-air supply arrangement includes an adjustable throttle device arranged in the suction line of the compressor. The throttle device is adjustable between a fully open load position and an idle position with a predefined narrowed throttle cross section. The idle power of the compressor is reduced as a result of the reduction of the pressure level downstream of the throttle device without additional lines, filters or the like.
