ABSTRACT:
A gas compressor of the pitot type is equipped with means for separating liquid, entrained in supply gas to be compressed, from the supply gas prior to introduction of the supply gas into a pumping chamber within the compressor. A rotary casing is mounted for rotation in a selected direction about an axis of the compressor. A gas supply passage, for delivering a gas to be compressed, has an outlet to the interior of the casing. A compressed gas discharge duct leads from the compressor coaxially with the casing. A pitot tube extends radially from the compressor axis in the casing and has, adjacent its outer end, an inlet which faces in a direction opposite to the direction of rotation of the rotary casing. The pitot tube has a diffuser passage connected to the inlet and extending toward the casing axis to an outlet port connected to the compressed gas discharge duct. Liquid separating means are cooperatively associated with the gas supply passage upstream of its outlet for centrifugally separating liquid from gas in the supply passage. The liquid separating means are mounted for rotation with the casing.
