Abstract
A unique positioning of a discharge tube relative to a pivot axis of a check valve in a compressor reduces the wear and fatigue stresses on the pivoting check valve components. The tube is centered on an axis that is non-perpendicular to an axis that is parallel to the pivot axis of the check valve, and in one embodiment was at 45°. With the inventive positioning of the discharge tube relative to the pivot axis, the flow streamlines heading from the discharge port to the discharge tube are no loner normal to the flapper valve surface, and the amount of wear between moving valve components and fatigue stresses are reduced.
