ABSTRACT:
In a compressor where an oil pump is driven by a crankshaft through a drive tang with oil passing through the drive tang. The bolts holding the drive tang in place tend to agitate the oil and create foam. To prevent foam from being drawn into the oil pump, the agitation is isolated by a sub-chamber defined in part by a spring retainer while oil is supplied via a tube extending through the sub-chamber.
