<p>An improved oil supply apparatus for a friction portion of a linear compressor which is capable of enhancing the lubricating performance of the piston by substantially supplying oil to the fricton portion between a cylinder (122') and a piston (129), thus enabling a desired reciprocating movement of the piston (129), which includes a cylinder (122') having a plurality of oil introducing holes (122a) for communicating the inside and the outside of the cylinder (122'); an oil mass (131) disposed between the cylinder and a core liner spaced apart from the cylinder (122') and slidable whithin an oil pocket (132) communicating with the cylinder (122') by an oil suction hole (143c); an elastic member (133, 134) for elastically supporting the oil mass (131); and a valve assembly (139') for a refrigerant gas flowing path for guiding the flowing of the refrigerant gas, a suction gasket (141) integral with an oil flowing path for guiding the flowing of the oil supplied to and discharged from the friction portion between the cylinder (122') and the piston (129), a suction valve (142), a valve sheet (143), a discharging valve (144), a discharging gasket (145), and a head cover (146).</p> |
