ABSTRACT:
Improvements in a compressor unit of the type which includes a radial piston compressor and a drive motor disposed in a housing about a stationary shaft are disclosed. The shaft is suspended from the housing by an elastic coupling to substantially suppress the transmission of vibrations and sound from the compressor unit to the housing. In a disclosed embodiment, the shaft is suspended by a rod-shaped elastic support member fastened to the housing and protruding into a cavity defined by a hollow portion of the shaft where the elastic member is connected to the shaft. According to one aspect of the invention, transmission of vibration and sound can be attenuated without the need to provide additional space by providing the unit's pressure outlet duct as the elastic support member.
