1. A suspension system for a compressor assembly comprising at least one cylinder, at least one piston reciprocating within the at least one cylinder along a reciprocating axis, at least one inlet fluidly connected with the at least one cylinder, an outlet fluidly connected with the at least one cylinder, and a motor housing, the suspension system comprising:
a suspension member comprising:
a coupling portion coupled with the motor housing of the compressor assembly; and
a first fluid conduit connected with the coupling portion and comprising a first fluid terminal disposed at one end of the first fluid conduit, wherein the first fluid terminal is configured to be fluidly connected with one or more components, and wherein the first fluid conduit is disposed in fluid communication with one of the outlet and the at least one inlet of the compressor assembly;
a second fluid conduit spaced apart from the first fluid conduit and connected with the coupling portion, wherein the second fluid conduit is disposed in fluid communication with the other one of the outlet and the at least one inlet of the compressor assembly, wherein the second fluid conduit comprises a second fluid terminal disposed at one end of the second fluid conduit and configured to be fluidly connected with one or more components; and
a frame member comprising:
a base portion;
a first support portion extending from the base portion and coupled with the first fluid terminal of the first fluid conduit, such that a first mounting region is formed between the first support portion and the first fluid terminal, wherein the first mounting region defines a first volume that at least partially encloses the first fluid terminal and is disposed on a first side of the suspension member; and,
a second support portion extending from the base portion and spaced apart from the first support portion, wherein the second support portion is coupled with the second fluid terminal, such that a second mounting region is formed between the second support portion and the second fluid terminal, wherein the second mounting region is spaced apart from the first mounting region and defines a second volume that at least partially encloses the second fluid terminal and is disposed on a second, opposing side of the suspension member;
wherein the suspension member defines a support axis passing through the coupling portion, the first volume, and the second volume, such that the support axis is approximately co-planar with a center of gravity of the compressor assembly within a plane orthogonal to the reciprocating axis; and
wherein the weight of the compressor is supported essentially entirely at the first and second fluid terminals via the first and second fluid conduits and the coupling portion.
