Abstract

PURPOSE: To improve the lubrication to vanes by providing the first communicating hole for feeding the lubricating oil to a vane chamber and the second communicating hole for communicating the upper vane chamber with the lower vane chamber.
CONSTITUTION: When the operation is started, a communicating hole 27 opens, attending on the movement of a lower vane 15 to the left, and the volume of a vane chamber 17 is increased so as to be the negative pressure, and the lubricating oil 24 flows into the vane chamber 17 through the lower communicating hole 27. Next, when the lower vane 15 moves to the right, the lower communicating hole 27 is closed so that the oil pressure in the vane chamber 17 rises, and an upper vane 14 moves to the left so that the vane chamber 16 is made to be the negative pressure, and the lubricating oil 24 flows into the vane chamber 16 through a communicating hole 28. Next, when the upper vane 14 moves to the right, the oil pressure in the upper vane chamber 16 rises, and the lubricating oil 24 in the upper vane chamber 16 is exhausted to the outside of an upper plate 12 through an upper communicating hole 29.
