ABSTRACT:
The invention is an apparatus for distributing a lubricant to the air guns in a single airline seismic air gun subarray which utilizes an air-lubricant mixture to operate and lubricate the air guns in the subarray. The air-lubricant mixture from the single airline is supplied to each air gun through a separate adapter and a cut-off valve. The lubricant tends to accumulate near the first several air guns, which wind up using most of the lubricant contained in the mixture while leaving no or very little lubricant for the remaining air guns. To prevent this uneven distribution of the lubricant, a lubricant metering device is placed in certain adapters to control the amount of the lubricant supplied to their associated air guns. Using the lubricant metering device to control the lubricant supply to the air guns in a subarray ensures that all the air guns receive adequate lubricant supply.
