Natural gas compressor
First Claim
1. A natural gas compressor, comprising:
- a housing;
a plurality of cylinder piston assemblies disposed within the housing, each assembly comprising a non-lubricated piston for compressing natural gas within a cylinder of the assembly, wherein the plurality of cylinder piston assemblies are fluidly connected in sequence such that each assembly forms a compression stage of the compressor; and
a drive system for moving the pistons of the cylinder piston assemblies to compress natural gas within the cylinders of the assemblies, wherein the drive system comprises a drive shaft and, for each assembly;
an eccentric connected to the drive shaft and a connecting rod, wherein the rotation of the drive shaft rotates the eccentric and oscillates the connecting rod;
a driving member connected to the connecting rod, wherein oscillation of the connecting rod oscillates the driving member;
a pivoting member connecting the driving member to the housing, wherein the driving member pivots about the pivoting member; and
a piston push rod connected to the driving member and engaging the piston of the assembly, wherein oscillation of the driving member moves the piston to compress natural gas within the cylinder of the assembly; and
wherein each driving member is connected to the corresponding piston push rod by a connection; and
each piston push rod is supported by upper and lower bushings, the upper bushing located above the connection of the driving member and the lower bushing located below the connection of the driving member.
