摘要： Horizontal Crankshaft Hermetic Compressor for use in refrigeration appliances. According to the present invention the compressor is fitted out with an oil pump having features of positive displacement, which ensures even at start up moments of the compressor an efficient lubrication of the bearings. The oil pump proposed has low energy consumption and supplies a continuous and adequate oil flow for lubricating the compressor without affecting in any perceivable manner its efficiency. According to the invention, the oil pump comprises a cylindric and eccentric portion (23) of the crankshaft (7) which is disposed with a flexible blade (25) within a cylindrical housing (26). This cylindrical housing (26) is provided in one of the bearings (5,6) supporting the crankshaft (7) or in a front cover (37) of the sub bearing (6). The blade (25) defines with the housing (26) an admission (29) and a pressure chamber (30) of the oil pump which are in fluid communication respectively with the oil sump (34) and the parts of the compressor unit requiring lubrication.
