Abstract
The present invention relates to an oil level sight glass for a compressor. The oil level sight glass is at an angle relative to a longitudinal housing axis, such that it can be rotated to achieve an improved position for seeing the sight glass. The sight glass housing further includes an oil return valve which permits return of oil into the oil sump through the sight glass housing.
