ABSTRACT:
A scroll compressor including a hermetic housing with a motor-compressor unit disposed therein, including fixed and orbiting scrolls. The fixed scroll defines perpendicular axial and radial directions, and includes an outer wall having a suction inlet facing substantially in the radial direction. A baffle member is associated with the suction inlet of the fixed scroll, and in one embodiment, is attached to the fixed scroll with fasteners. The baffle member includes a first open end facing in the axial direction toward a suction port of the compressor housing, and a second open end facing in the radial direction in fluid flow alignment with the suction inlet of the fixed scroll. The baffle member directs a portion of the working fluid which enters the compressor housing substantially directly into the suction inlet of the fixed scroll to reduce turbulent flow of the working fluid within the compressor housing, improving the operating efficiency of the compressor.
