Abstract:
1. A multi-stage compressor capable of compressing and pumping multiple liquid and gaseous phases with entrained phases comprising: a source of input fluid, a first stage compressing means comprising a low-pressure compression cylinder and a low-pressure ram compressing means, a second stage compressing means comprising a high-pressure compression cylinder of equal inside diameter to said low pressure compression cylinder and a high-pressure ram compressing means, a common valve assembly head joining said low-pressure compression cylinder and said high-pressure compression cylinder, a common housing containing said first stage compressing means and said second stage compressing means, a means for activating and deactivating each of said ram compressing means, a multi-directional control means for controlling said activation and deactivation, an inlet means for transferring said input fluid into said compressor and charging said first stage compressing means with gas in said fluid, a fluid transfer means in said common valve assembly head for transferring fluid between said low-pressure compression cylinder and said high-pressure compression cylinder, a compression control means for limiting compression in each of said compressing means, a destination for fluid compressed by said compressor, an outlet means for releasing said compressed fluid from said compressor and transferring it to said destination, heat-exchange means for cooling each of said compressing means, a pumping means for circulating hydraulic fluid to drive said ram compressing means, and a power supply to power said pumping means.
