摘要：
An oil pumping system for a reciprocating hermetic compressor having a shell, which defines in the interior thereof an oil sump; a motor compressor assembly; and an oil pump means. The oil pump means is coupled to the compressor by at least one dampening resilient means. The dampening resilient means is dimension to reduce the amplitude of displacement of the oil pump means to a value that is calculated so that the ratio between the natural frequency of resonance (Wn) of the oil pump means and an operation frequency (W) of the compressor results in a ratio between the displacements of the oil pump means and of the compressor with a value inferior to one.
