ABSTRACT:
Suction gas feed assemblies to provide gas to a hermetic compressor are provided. The feed assemblies have capacity for reducing suction noise resulting from suction conduit vibration, valving operation, suction gas pulsing, or the like. The suction gas feed assemblies include a suction plenum in the form of a substantially cylindrical end cap or motor cap having substantially straight side wall, a contoured top wall, and a gas inlet aperture and suction conduit aperture which are configured to provide strong suction and motor cooling, with reduced superheat, suction pulsation, and noise attenuation. The motor cap has excellent structural stiffness and low sound radiation.
