Abstract:
1. A reciprocating compressor comprising: a frame including: a crosshead disposed within each of the first and second crosshead guides a crankshaft disposed within the interior volume and coupled to each crosshead via a connecting rod, wherein the crankshaft and each crosshead are configured such that rotation of the crankshaft during operation induces linear motion of each crosshead within the respective crosshead guide wherein the first crosshead guide and its associated oblique support structure are opposed to and at least partially axially overlap the second crosshead guide and its associated oblique support structure along the hollow central body such that during operation the oblique support structures of the first and second crosshead guides reduce a coupled moment of the frame resulting from the induced linear motion of the crossheads within the respective first and second crosshead guides.
