Reciprocating integral linear engine compressor

A reciprocating compressor for moving a process fluid from a suction line to a discharge line, comprising:

• a hollow cylinder tube having a central bore;
• a piston assembly operable to reciprocate within the central bore, the piston assembly having two pistons and a piston rod, each piston having an outer end and an inner end, with the inner ends being connected with the piston rod;
• a pair of end plates, one end plate at each end of the cylinder tube, each end plate configured to provide a sealed outer chamber between the end plate and an outer end of the piston proximate to respective end plate;
• wherein each sealed outer chamber and the outer end of the proximate piston form a power cylinder;
• each power cylinder further comprising an igniter, an air intake valve, and an exhaust valve;
• a center divider in the central bore between the inner ends of the pistons, the center divider having an aperture operable to allow the piston rod to reciprocate through the center divider;
• wherein the inner end of each piston defines an inner chamber between each inner end and the center divider;
• wherein each inner chamber and the inner end of the proximate piston form a compression cylinder;
• wherein each compression cylinder further comprises a discharge valve and a suction valve;
• a common suction manifold shared by the suction valves of the compression cylinders;
• wherein each suction valve is in direct fluid communication from the respective compression cylinder to the common suction manifold;
• a common discharge manifold shared by the discharge valves of the compression cylinders;
• and wherein each discharge valve is in direct fluid communication from the respective compression cylinder to the common discharge manifold;
• wherein reciprocating movement of the piston assembly alternatingly opens and closes the suction valves such that the compression chambers alternatingly receive process fluid via the common suction manifold, and alternatingly opens and closes the discharge valves such that the compression chambers alternatingly discharge the process gas via the common discharge manifold.
