Valve arrangement

A valve arrangement for a liquid ring system comprising:

• a plurality of plates arranged to face each other, comprising a first plate and a second plate spaced apart by a first distance, and each plate of the plurality of plates comprising at least one valve, wherein each of the plurality of plates is configured to be rotatable about a first axis at a first speed;
• a vane set disposed between the first plate and the second plate, each vane of the vane set having a first face and a second face;
• a chamber set comprising at least one chamber, wherein a first chamber of the chamber set is bounded by the first plate, the second plate, the first face of a first vane of the vane set, and the second face of a second vane of the vane set, wherein each vane of the vane set is impermeable to a working fluid and each vane extends between the first plate and the second plate to prevent the working fluid from bypassing the vane, in use, when the working fluid is disposed between the first plate and the second plate;
• and
• wherein the first chamber of the chamber set comprises:
• a first valve of the at least one valve, disposed on the first plate, wherein at least a portion of the first valve of the at least one valve is configured to be closer to the first face of the first vane of the vane set than the second face of the second vane of the vane set;
• and
• a second valve of the at least one valve, disposed on a second plate, wherein at least a portion of the second valve of the at least one valve is configured to be closer to the second face of the second vane than the first face of the first vane.
