| A liquid ring vacuum pump or compressor includes an off-centered housing and a rotor shaft assembly within the housing. The liquid ring vacuum pump or compressor also includes a port-containing one member having a frustoconical shape positioned in the rotor. The rotor rotates liquid around the cone member forming an off-centered cylindrical liquid ring that is shaped by and centered in the off-centered housing. The invented cone member has an inlet port having a parabolic shaped opening edge and a discharge port having a parabolic shaped closing edge. The invented cone member fully supports the liquid ring, at the intersection of the inner surface of the cylindrical liquid ring and the outer surface of the wall of the frustoconical cone member and inhibits the flow of water into the ports, maximizes the amount of gas being displaced through the cone member, increases the capacity of the liquid ring vacuum pump, and reduces the cost of operating the pump. A method of reducing water usage in a liquid ring vacuum pump is also disclosed. | ||||||

| 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.

| A liquid ring pump with a conical or cylindrical port member has a vent-recirculation port in the port member in addition to the conventional intake and discharge ports. The vent-recirculation port communicates with the compression zone of the pump and is connected to a reservoir of pumping liquid maintained in the discharge portion of the pump head. When the pump is operating at relatively low compression ratios, the vent-recirculation port acts as a vent to prevent overcompression of the gas in the pump. At relatively high compression ratios, the vent-recirculation port recirculates pumping liquid from the reservoir, thereby increasing the maximum attainable compression ratio. | ||||||

| An improved water ring rotary air compressor in which the rotor assembly has a cylindrical bore while the port head includes a cylindrical port sleeve, made from a high lubricity thermoplastic material, which fits within the bore. The use of a high lubricity thermoplastic port sleeve eliminates the need for shimming the port head following an overhaul of the compressor. The port sleeve includes a plurality of longitudinal slots which eliminate cavitation during start up under pressure. A needle valve built into the manifold allows bypass of a portion of the discharge air into the air inlet. Adjustment of the needle valve permits the maintenance of constant air flow as the compressor becomes worn. | ||||||
