Title:
ENCLOSED COMPRESSOR
Document Type and Number:
Japanese Patent JP2007100670
Kind Code:
A
Abstract:
To provide an enclosed compressor of high volumetric efficiency and efficiency by surely projecting oil to an upper part of a piston and improving sealing performance between the piston and a cylinder.
An inner opening part 114a in a communication hole 113 of an oil discharge path 114 opens to an eccentric shaft direction of an eccentric shaft part 110, and an outer opening part 114b in an outside space of the eccentric shaft part 110 of the oil discharge path 114 is offset to the eccentric shaft direction in an anti-rotation direction of a crankshaft. Consequently, the hermetic compressor which can surely project oil to the upper part of the piston, and which has high reliability, high volumetric efficiency and efficiency can be provided.
