Reciprocation-typed compressor

A reciprocation-typed compressor includes a shell, a base, a rotational shaft, a driving mechanism, a piston, and a linkage. The base has a cylinder, which has an oiling passage, an inlet, a plurality of outlets each communicating with the inlet and inside of the shell, and a through hole communicating with one of the outlet and inside of the cylinder. The rotational shaft is rotatably mounted to the base, having a main oiling passage and an auxiliary oiling passage extending at a predetermined angle and communicating with the inlet. The driving mechanism is provided for driving the rotation of the rotational shaft. The piston is freely slidably mounted in the piston. The linkage has an end mounted to the rotational shaft and the other end mounted to the piston. While the rotational shaft is driven to rotate, the linkage drives the piston to reciprocate inside the cylinder, such that the cylinder and piston can be effectively cooled and lubricated to reduce the power assumption and to elongate the life for the compressor.
