The gaseous coolant that exhaust outlet 32 flows out lets out.Certainly, auxilairy air intake 22 can pass through pipeline and the phase of the first air inlet 21
Connection.
As shown in figure 1, the rotary compressor of embodiment one also includes upper flange 23, upper flange 23 is arranged on the first receiving
Intracavitary is simultaneously fixed on cylinder body 20, and upper flange 23 plays a part of and the formation compression chamber of cylinder body 20.Upper flange 23, which has to wear, to be let out
The installation through-hole of pressure valve 30, installation through-hole is corresponding with auxilairy air intake 22.Upper flange 23 plays fixation to relief valve 30,
Can make that second exhaust port 32 is connected with the first air inlet 21 is more stable.
As shown in figure 3, in embodiment one, relief valve 30 also includes valve body 33, valve element 34 and dynamic clamping head and quiet clamping head 35.Valve body
33 include the second accommodating chamber, and the second air inlet 31 and second exhaust port 32 are arranged on valve body 33, and valve element 34 is movably disposed
In the second accommodating chamber, valve element 34 has the second air inlet 31 and second of block-up position and conducting of the second air inlet 31 of closure
The conduction position of exhaust outlet 32.When valve element 34 is in block-up position, the second air inlet 31 and second exhaust port 32 are in breaking shape
State, when valve element 34 is on position, the second air inlet 31 and second exhaust port 32 are in channel status.Dynamic clamping head and quiet clamping head 35 is set
Put between valve element 34 and second exhaust port 32.In the presence of dynamic clamping head and quiet clamping head 35, the second air inlet 31 and second exhaust port
32 are in off state.Above-mentioned relief valve 30 it is simple in construction, and can be changed by changing the elastic force of dynamic clamping head and quiet clamping head 35
Become the second air inlet 31 and second exhaust port 32 in the gaseous coolant pressure needed for channel status.
The rotary compressor of embodiment two and the difference of embodiment one are, add pressure regulator valve.Specifically, implementing
In example two, pressure control device also includes pressure regulator valve, including the 4th air inlet and the 4th exhaust outlet, the 4th air inlet and the 4th row
