Abstract
A closed-type transmission compressor comprises an upper shell having a compressing unit and a lower shell having a transmission unit. The transmission unit includes a stator which generates magnetic power, a rotor rotated by the magnetic power of the stator, and a crankshaft rotated by rotation of the rotor. The compressing unit includes a slider changing rotatory movement of the crankshaft into linear movement, a piston attached to the slider and reciprocating in a cylinder, a head cover covering the cylinder, an inlet valve between a head and a head cover which permits intake of a refrigerant gas, an outlet valve between the head and the head cover which permits exhaust of the refrigerant gas, a propeller conveying oil in the lower shell into the crankshaft, and a screw-shaped oil path groove formed in the inside of crankshaft along which the oil is flowed.
