Several arc-shaped grooves 13 are provided along the circumference of the first valve plate 9, the second valve plate 10, and the third valve plate 11. The arc-shaped grooves 13 on the first valve plate 9 and the third valve plate 11 are in the same position, while the arc-shaped grooves 13 on the second valve plate 10 are staggered from those on the first valve plate 9 and the third valve plate 11.
