Patent ID: 7086840

Claim:
An oil pump in a reciprocating hermetic compressor presenting a shell, which defines in the interior thereof an oil sump, and which lodges a cylinder, inside which reciprocates a piston, comprising a tubular pump body, having a free end immersed in the oil, and an opposite end connected to a lubricant oil directing tube, which conducts said oil to the compressor parts with relative movement, said pump body being coupled to the compressor, so as to be actuated in a reciprocating axial movement, said pump body defining at the free end thereof a valve seat, and further lodging a sealing means, which is displaced between a closing position, seated on said valve seat, and an opening position, spaced from said valve seat, the opening and closing positions being obtained when the reciprocating movement causes, respectively, a displacement of approximation and spacing of the pump body in relation to the sealing means therewithin.
