Abstract
The present invention includes a case, a driving motor, a rotating shaft, a cylinder having a compression space formed in a central portion thereof, a roller, a main bearing and a sub bearing, and a vane for partitioning the compression space into a suction chamber and a compression chamber, wherein the vane includes a vane housing provided with a space portion and a communication hole formed through one side of a front end portion thereof to form a flow path of a compressed refrigerant, and a valve member slidably installed in the space portion of the vane housing and selectively communicating the space portion with the compression chamber, wherein the flow path of the compressed refrigerant is formed by the movement of the valve member.
