Suction muffler for compressor |
摘要 |
To prevent oil from being drawn into a suction muffler of a compressor, a suction muffler 7 is disposed in a compressor casing at an inlet of a compression chamber at an upstream side of a refrigerant passage and positioned so that the suction muffler 7 receives oil, in which an upper lid member 71, and a lower lid member 72 having a bottom wall to which refrigerant introducing and leading-out pipes 8, 72d are connected, are fitted and secured by bringing an inner face of a side wall of the member 71 into tight contact with an outer face of a side wall of the member 72, and a protruding portion 72f is provided by forming a lower end of side wall of the member 71 to protrude below a lower face of bottom wall of the member 72, to surround connecting portions of the pipes 8, 72d. |

1. A suction muffler for a compressor, the suction muffler being disposed in a compressor casing at an inlet of a compression chamber on an upstream side of a refrigerant passage and disposed at a location at which the suction muffler receives oil sprayed from above in the casing,
wherein an introducing pipe and a leading-out pipe of a refrigerant are connected upward to the suction muffler from beneath the suction muffler, and wherein at an outside of connecting portions of the introducing pipe and the leading-out pipe of the refrigerant, each of which is connected to the suction muffler, a protruding portion which protrudes below the connecting portions and surrounds the connecting portions is provided, the suction muffler comprising: an upper lid member which has an open lower face; and a lower lid member which has an open upper face and a bottom wall to which the introducing pipe and the leading-out pipe of the refrigerant are connected, wherein an inner face of a side wall of the upper lid member is joined to an outer face of a side wall of the lower lid member, to be fitted and secured thereto, and wherein the protruding portion is provided by forming a lower end of the side wall of the upper lid member to protrude below a downward facing surface of the bottom wall of the lower lid member connected with the introducing pipe and the leading-out pipe of the refrigerant. |
