１１、シリンダヘツド……６、吐出管……１２。 FIG. 1 is a sectional view corresponding to FIG. 4a showing one embodiment of the present invention. Figures 2 to 4 show an example of a conventional compressor, with Figure 2 being a front view, Figure 3 being a partial sectional view of the cylinder head, and Figure 4a being taken along the - line in Figure 3. The cross-sectional view, FIG. 4b, is a diagram showing the pulsating pressure of the primary resonance mode resonated within the discharge cavity. Figure 5a shows the frequency analysis results in the discharge cavity, Figure 5b shows the frequency analysis results in the discharge pipe of the compressor according to the present invention, and Figure 6c shows the frequency analysis results in the discharge pipe of the conventional compressor. It is a line diagram. FIG. 6 is a sectional view corresponding to FIG. 4a showing a second embodiment of the present invention. Cylinder...4a, 4b, discharge cavity...

補正昭６３．７．１８図面の簡単な説明を次のように補正する。明細書第６頁第４行目の「第６図ｃ」を「第５
図ｃ」に補正します。Amendment July 18, 1983 The brief description of the drawing is amended as follows. "Figure 6 c" on page 6, line 4 of the specification has been replaced with "Figure 5.
Correct it to "Figure c".

Claims

[Scope of utility model registration request]

In a compressor having a cylinder head in which a discharge cavity common to a plurality of cylinders is formed,
A compressor characterized in that the discharge pipe is opened near a position where the pulsating pressure of the primary resonance mode resonated within the discharge cavity becomes zero.
