Enclosed compressor

In a sealed type compressor, an oil supply groove (14b) is not a communicating groove open at the upper and lower ends, and extends only to a region partway of a bearing portion (14a) at a lower end side of a crankshaft (26). As a result, the lubricant supplied to a lower bearing (14A) is entirely a...

More Information
Summary:In a sealed type compressor, an oil supply groove (14b) is not a communicating groove open at the upper and lower ends, and extends only to a region partway of a bearing portion (14a) at a lower end side of a crankshaft (26). As a result, the lubricant supplied to a lower bearing (14A) is entirely applied to the lower bearing (14A) without a portion being discharged to an oil reservoir. By employing such a configuration to reduce futile drawing of the lubricant at an oil pump, there can be provided a sealed type compressor that allows the oil supply capability of the oil pump to be improved to suppress occurrence of pump loss.
