ABSTRACT:
An apparatus for exchanging pressure energy between a fluid having a high energy content as a result of pressurization, and a fluid having a relatively lower pressure. The apparatus includes a rotor which has a plurality of spaced tubes extended in substantially parallel array over a major portion of the rotor length, and each having a separatory member movably mounted therein for reciprocatory displacement in the respective tube. Each of the fluid conveying tubes has its opposite ends movably but sealingly received in recesses in; floating rotor seal plates. Each seal plate further includes an arcuate port which completes the opening formed by both the recess and port through the seal plate. The opposite side of each seal plate from that which contains the recesses into which the respective tubes extend bears sealingly against a fixed stator block. In the side thereof which faces and sealingly contacts the seal plate, each of the stator blocks has a pair of spaced arcuate fluid distribution ports each positioned to sequentially and periodically register with the arcuate ports of the adjacent seal plate during rotation of the rotor and seal plates. Each of the arcuate fluid distribution ports communicates with a generally cylindrical fluid passageway which opens from the opposite side of the respective stator block, and in conjunction with the communicating arcuate fluid distribution port, facilitates fluid passage through the stator block. A rotor drive mechanism is provided for rotating the rotor about a central longitudinal axis which extends centrally through the seal plates and the stator blocks.
