Embodiment
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment 1
The present invention is a kind of reciprocating slant plate type compressor structure, as shown in Figure 1 and Figure 2, is a kind of structural representation of reciprocating slant plate type compressor structure.Center in cylinder body 13 is provided with main shaft 6, sealed by sealing axle sleeve 9 between cylinder body 13 and main shaft 6, main shaft 6 is connected with bearing 11, main shaft 6 is provided with the swash plate 8 be connected with bearing 11, swash plate 8 is connected with piston 14 by hemisphere 7, main shaft 6 has main shaft vent 12, cylinder body 13 has cylinder vent 10, sealing axle sleeve 9 has attachment hole 15.The two ends of main shaft vent 12 are connected with adjacent two attachment holes 15 respectively.Attachment hole 15 communicates with cylinder vent 10, and cylinder vent 10 is corresponding with attachment hole 15.Clearance L is positioned at the endface position of cylinder body 13 inner casing, and clearance L communicates with cylinder vent 10.
The cross section of the cross section of cylinder vent 10, the cross section of attachment hole 15 and main shaft vent 12 is circle, square or oval.The section area of cylinder vent 10, the section area of attachment hole 15 are identical with the section area of main shaft vent 12, and are all not more than 7 square millimeters.
Now in conjunction with 5 cylinders in 10 cylinder machines, the present invention will be described, and other 5 cylinder structures are identical.All there is clearance L in the top of the first cylinder 1, second cylinder 2, the 3rd cylinder 3, the 4th cylinder 4, the 5th cylinder 5.In the present embodiment, the cross section of main shaft vent 12 is " V " font, and the angle on " V " font main shaft vent 12 both sides is 144 °.
As shown in Figure 1 and Figure 2, the first cylinder 1 is exhaust done state; Second cylinder 2, the 3rd cylinder 3 are suction condition; 4th cylinder 4, the 5th cylinder 5 are compressive state.
