Abstract:
1. A lubrication system for a natural gas compressor, in which a lubricant is periodically injected into the compressor cylinder through a check valve that prevents natural gas from entering the lubrication system, comprising: a device positioned between the compressor cylinder and the check valve to maintain an oil seal to prevent natural gas from fouling the check valve, the device having a fill capacity that requires less than 10 cycles of a lubricant pressurization device to fill the fill capacity, the device further comprising two bores cut into a solid plug having a threaded end for attaching to the compressor cylinder, one bore leading to the compressor cylinder and the other bore leading to a threaded opening for attaching the check valve, the two bores being in open fluid communication with one another within the plug; the device including a path for lubricant, the direction of the path changing within the device to trap oil between the check valve and the compressor within the path for lubricant; and wherein the lubricant pressurization device is in fluid communication with the device and supplies no more than 0.098 cm
