Patent ID: 7070397

Claim:
A suction gas feed assembly for a hermetic compressor unit having an electric motor driven compressor mechanism mounted in the feed assembly comprising: a motor cap comprising: a circumferential sidewall, the sidewall comprising a suction conduit aperture and a gas inlet aperture, the suction conduit aperture being disposed opposite and in substantial alignment with the gas inlet aperture; a top wall disposed adjacent the sidewall and being configured to form a closed end, the top wall comprising protruding portions and recessed portions, the protruding portions and recessed portions being configured and disposed to control and direct the flow of suction gas within the motor cap to provide a substantially uninterrupted flow of suction gas between the gas inlet aperture and suction conduit aperture; an opening, the opening being disposed in substantial sealing contact with an unencumbered end of the motor to form a suction plenum for a compressor mechanism; a suction conduit having a first end and a second end opposite the first end, the first end of the suction conduit being mounted in the suction conduit aperture in the sidewall, the second end of the suction conduit being configured for subsequent connection to compressor mechanism; wherein the motor cap has a substantially cylindrical shape with a substantially straight sidewall, the sidewall having a substantially circular horizontal cross-sectional geometry defined by a major axis and a minor axis, the major axis dividing the motor cap into two hemispheres; wherein the top wall and the sidewall intersect to form an outwardly curved annular circumferential portion extending around the perimeter of the end cap; wherein the recessed portions of the top wall comprise a recessed cylindrical portion centered at the intersection of the major and minor axis; wherein the protruding portions of the top wall comprise a raised bridge portion having a peak extending from the recessed cylindrical portion to the outwardly curved circumferential portion, the longitudinal axis of the peak in substantial alignment with the major axis; and wherein the suction conduit aperture, gas inlet aperture, and the peak are all located on one half hemisphere of the motor cap.
