<p>PROBLEM TO BE SOLVED: To reduce noises by arranging an interposing member between a valve plate and a cylinder head, and providing a resonance chamber with a pressure introducing part communicating with a suction hole. SOLUTION: A resonance space 60 is constituted between a valve plate 6 surface and a cylinder head. A resonance chamber 60 is formed out of a first plate 50 and a second plate 51. The first plate 50 and the second plate 51 have a hole part being a hole D having the same diameter as a suction hole 31. The first plate 50 has a through hole part 500 having the diameter D. The second plate 51 has a hole part 510 of the diameter D, and plays a role of a top plate for blocking up the hole part 500 of the first plate from above. The first plate 50 is placed on it by adjusting the suction hole 31 of a valve plate 6 and the hole part 500 of the first plate 50. One hole part 500 is adjusted to and placed on a hole part 10 of the second plate 51, and is assembled by a fixing bolt by placing the cylinder head 5 to form a closed space to be formed as the resonance chamber 60.</p> |
