Part includes cylinder 11 (local display), described cylinder 11 is provided with a suction hole 12, and, described cylinder 11 has one
Suction muffler 13, described suction hole 12 is connected with suction muffler 13.
Wherein, described suction hole 12 includes the first paragraph 121 being connected and second segment 122, described second segment 122 and air-breathing
Chamber 13 is connected, and described first paragraph 121 is connected with the suction side (supply part) outside cylinder 11, and, described second segment 122
The minimum area of cross section be more than or equal to the area of first paragraph 121 and the cross section of second segment 122 intersection, and, institute
The minimum area stating the cross section of second segment 122 is the area of second segment 122 and the cross section of first paragraph 121 intersection.
Embodiment according to disclosed in Fig. 2, described second segment 122 is a variable section structure, specifically, oneself and first paragraph
The cross section of 121 intersections is risen, the area incremented by successively of the cross section of described second segment 122, that is, described second segment 122
Being shaped as of longitudinal section is trapezoidal, and trapezoidal top (minimum cross-sectional area) is connected with first paragraph 121, trapezoidal bottom
(maximum cross-sectional area) is connected with suction muffler 13.Embodiment according to disclosed in Fig. 2, when described second segment 122 is to become
During cross section structure, described first paragraph 121 is uiform section structure, that is, have equal cross-sectional area, now, described second segment
The minimum area of 122 cross section is equal to the cross-sectional area of first paragraph 121.
<embodiment two>
It is with the difference of embodiment one: the first paragraph 121 of the present embodiment is not a uiform section structure, but one
Individual variable section structure, referring particularly to Fig. 3.
Embodiment according to disclosed in Fig. 3, when described second segment 122 is variable section structure, described first paragraph 121 is corresponding
For a variable section structure, specifically, described first paragraph 121 is less than it with the area of the cross section of outer wall intersection of cylinder 11
With the area of the cross section of second segment 122 intersection, it preferably is selected from rising with the cross section of the outer wall intersection of cylinder 11, described first
