PURPOSE:To maintain a proper pressing force to the inside wall of a vane's cylinder and improve the durability and efficiency of a vane rotary type compressor by performing a proper lubrication to the back of a vane responding to rotary speeds of a vane rotary type compressor. CONSTITUTION:The higher the rotary speed of engine is, the greater the frequency of an outlet pulse of a single stability multi circuit is. An FV converter 20 lowers a terminal voltage for a magnetic coil 39. As illustrated in the figure, therefore, the balancing position between a rod 65 and a spring 61 moves upward and an opening ares between a ball valve 63 and a valve seat for a lubricating nozzle 62 is reduced and the amount of lubricant to be supplied for pressing a vane 46 to an inside wall of a cylinder 41. When the rotary speed of engine is lowered on the contrary, the terminal voltage of the magnetic coil 39 is increased, and then operates in reverse to the above. This construction provides a proper lubrication to the back of a vane constantly and properly maintains a pressing force to the inside wall of a cylinder 41 for a vane 46 responding to the inside wall 41 of the vane 46, thereby improving the durability and efficiency of the equipment. |
