There is partition intercommunicating pore 19, adjacent slide plate back side chamber is connected to by partition intercommunicating pore 19 on 15.It is vented as a result, more smoothly,
Exhaust resistance is smaller, and the structure of compression member 5 is simpler, easy to process.
Such as in Fig. 5-specific example shown in Fig. 7, cylinder is two and respectively cylinder 10 and the second cylinder 20, gas
There is slide plate back side chamber 12 on cylinder 10, there is on the second cylinder 20 second slide plate back side chamber 22, cylinder 10 and the second cylinder 20 it
Between be equipped with middle partition 15, there is on middle partition 15 partition intercommunicating pore 19, partition intercommunicating pore 19 respectively with slide plate back side chamber 12 and the
The connection of two slide plate back side chambers 22.After high pressure refrigerant enters in the first muffler 44 as a result, the slide plate back side can be passed sequentially through
Chamber 12, partition intercommunicating pore 19, the second slide plate back side chamber 22 are entered in the second muffler 54 or are entered inside shell 2, as a result,
It is vented more smooth.Certainly, the invention is not limited thereto, and in other embodiments of the invention, slide plate back side chamber 12 and second is slided
Piece back side chamber 22 can also by component other than partition intercommunicating pore 19, be for example set to connecting leg conducting connection outside middle partition 15
(example out not shown), preferably to meet actual requirement.
Further, the pressure at least one cylinder referring to Fig. 7, in partition intercommunicating pore 19 and two cylinders adjacent thereto
Contracting chamber pass through exhaust apparatus be connected to, that is to say, that partition intercommunicating pore 19 can in two compression chambers adjacent thereto wherein
One compression chamber is connected to (example out not shown) by exhaust apparatus, and partition intercommunicating pore 19 can also be with two adjacent thereto
Compression chamber is connected to (example as shown in Figure 7) by exhaust apparatus respectively.Thus, it is possible to preferably reduce exhaust resistance, improve
The whole efficiency of compressor.
Preferably, when partition intercommunicating pore 19, which passes through exhaust apparatus respectively with two compression chambers adjacent thereto, to be connected to,
Connect that is the compression chamber on each cylinder in partition intercommunicating pore 19 and two cylinders adjacent thereto passes through exhaust apparatus respectively
It is logical, such as in specific example shown in Fig. 7, middle partition 15 is equipped between cylinder 10 and the second cylinder 20, is had on middle partition 15
