PURPOSE:To prevent the liquid compression by forming a communication hole inside a vane and installing a valve body for opening and closing the communication hole and forming an inclined wall in the vicinity of a valve seat in the communication hole. CONSTITUTION:A communication hole 203 is penetration-formed from one surface side 1113 of a vane towards the other surface side 1114 inside the vane 111 in a housing 100, and a valve body 205 and a spring 206 are arranged onto a valve seat 204 in the intermediate part. An inclined wall 207 is formed, communicating to the valve seat 204 midway in the communication hole 203. When liquid is compressed, the valve body 205 is opened, and the liquid coolant in a compression chamber 130 is discharged to the other surface side. In the high speed revolution, the valve body 205 is shifted to the edge part 1111 along the inclined wall 207. Therefore, the liquid compression of the compressor is prevented, and the increase of discharge faculty over necessity in the high speed revolution can be prevented.
