ABSTRACT:
A double-lobe liquid ring gas compressor includes a port member having two circumferentially spaced intake ports and two circumferentially spaced discharge ports. The intake ports are axially offset from the discharge ports. The intake ports are connected to a common intake passage in the port member, and the discharge ports are similarly connected to a common discharge passage in the port member. These passages respectively communicate with intake and discharge manifolds in a head member which can be identical to the head member of a single-lobe liquid ring vacuum pump.
