Abstract
A weight biased check valve is located in a reflective muffler at the entrance thereof. As a result, both the check valve and muffler are located proximate to a compressor which minimizes both the package size and the volume trapped upon shutdown. The axis of the weight biased check valve is skewed whereby the weight biasing effect is reduced.
