Conducting unit, and conducting methods

Abstract

The invention relates to a delivering unit for gas, comprising a compressor ( 101 ) in a noise-insulation housing ( 20, 40 ), which comprises an inlet opening ( 27, 66 ) and a blow-out opening ( 24, 69, 70 ). An inlet tube ( 96 ) can pneumatically connect the inlet opening to the inlet of the compressor. An outlet tube ( 96 ) can connect the blow-out opening to the outlet of the compressor. A noise absorber ( 60, 80 ) having an inlet chamber ( 73, 97 ) and an outlet chamber ( 74, 98 ) may be accommodated in the noise-insulation housing. Neoprene may be used as lining for the inner walls of the noise-insulation housing. Sheets ( 131. 133 ) may be provided between the noise-insulation housing and the compressor. An inner heat sink ( 42 ) and an inner blower ( 48, 49 ) can cool the compressor. A heat sink ( 41 ) may form one side ( 40 ) of the noise-insulation housing. An outer blower ( 7 ) can cool the heat sink. Blind tubes can be used both at the inlet and the outlet, so as to suppress tonal sound. Moreover, the invention relates to corresponding delivering methods.
