[work of blade-tape compressor 10]
Then, the work of the blade-tape compressor of embodiment 10 is illustrated.
In the blade-tape compressor 10 of embodiment, rotary shaft 16 receives the rotation from the driving sources such as motor or engine
Turn driving force and rotates.With the rotation of rotary shaft 16, rotor 18 is shown with arrows into Fig. 2 in cylinder body room 14d
Direction of rotation R rotation.With the rotation of rotor 18, the volume in discharge chambe 21 (Fig. 2) expands and reduces repeatedly.About rotor
18 direction of rotation R, the stroke that discharge chambe 21 expands volume become suction stroke, and the stroke that discharge chambe 21 reduces volume becomes pressure
Indention journey.
In suction stroke, the refrigerant that suction chamber 20 is directed to via suction inlet 23 utilizes the (figure of suction passage 22
1) with the connection of discharge chambe 21 out of suction passage 22 inflow discharge chambe 21.Volume in compression travel, in discharge chambe 21
It reduces, refrigerant is compressed.The refrigerant for the high pressure being compressed by discharge stroke in from discharge chambe 21 flow into passing away 52,
Pressing is discharged valve portion 62 and makes that the rearward bending deformation of valve portion 62 is discharged.Refrigerant is arranged by opening 77 to discharge room 35a
Out.Passing away 52 is formd a part of discharge chambe 21 and the discharge room 35a discharge path being connected to.
In such a series of stroke, it is subject to because of the centrifugal force being subject to when rotor 18 rotates and from back pressure chamber 41
Back pressure, blade 19 is from stress on the direction outstanding blade groove 18a, and the top of blade 19 is on one side and the inner peripheral surface of cylinder body room 14d
14c contacts one side moving in rotation.Have the top end face effect of blade 19 by blade from the elliptoid inner peripheral surface 14c of cylinder body 14
19 power pressed to the direction for submerging blade groove 18a.Because by the power acted on above-mentioned opposite direction, blade 19 with
The rotation of rotor 18 and stretch out and submerge repeatedly from blade groove 18a.It is contacted by blade 19 with the inner peripheral surface 14c of cylinder body room 14d, from
And zoning goes out discharge chambe 21 between adjacent blade 19 (referring to Fig. 2).
The refrigerant for being discharged to discharge room 35a flows to oil separation chamber 36s by the access 36k that communicates from discharge room 35a.System
Lubricating oil contained by cryogen is separated from refrigerant in oil separation chamber 36s.Refrigerant after isolating lubricating oil is via row
Outlet 37 is discharged to the external of blade-tape compressor 10.
The lubricating oil come is separated from refrigerant in oil separation chamber 36s, flows into reservoir compartment 35b from oil separation chamber 36s and is store
It is stored in the bottom of reservoir compartment 35b.Lubricating oil is due to the pressure of the refrigerant in reservoir compartment 35b successively via oil-through-hole 75, logical oil
Hole 65, back pressure feed trough 55 and connectivity slot 54 are supplied to back pressure chamber 41, act on back pressure to blade 19.
[effect and effect]
Then, the effect and effect of the blade-tape compressor 10 of above-mentioned embodiment are illustrated.
Under the steady running state of blade-tape compressor 10, the pressure for the lubricating oil stored in reservoir compartment 35b is enough
Height, therefore it is able to carry out the supply of stable back pressure.On the other hand, sometimes in the starting of blade-tape compressor 10, to store oil
The pressure that lubricating oil in the 35b of room applies does not rise sufficiently, and keeps blade 19 insufficient from blade groove 18a back pressure outstanding.?
In this case, it is unable to maintain that the state that the top of blade 19 is contacted with the inner peripheral surface 14c of cylinder body room 14d, blade 19 and cylinder body room
The inner peripheral surface 14c of 14d is intermittently collided, and it is therefore possible to generate noise (chattering, flutter).
For the phenomenon, in the blade-tape compressor 10 of embodiment, pilot channel 53 is opened and closed when stopping
Open and close valve 80 become opening state, in the starting of blade-tape compressor 10, discharge room 35a it is low with the pressure difference of back pressure chamber 41
In threshold value, open and close valve 80 is in an open state.Specifically, during the pressure difference of discharge room 35a and back pressure chamber 41 is small, such as Fig. 6
Shown, restriction plate portion 63 is indeformable, and sphere 64 is located at from the position that the conical surface 53 has left because of self weight.After sphere 64 is not connected to
Side plate 50 is formed with gap between sphere 64 and back side panel 50.It is compressed in discharge chambe 21 and is discharged to discharge room 35a's
The refrigerant gas of high pressure is flowed by the gap guide pressure passageway 53, and is supplied to back pressure chamber 41.53 shape of pilot channel
At a part on the pilot road for being connected to discharge room 35a with back pressure chamber 41.Pressure in back pressure chamber 41 promptly rises, to leaf
Piece 19 supplies enough back pressures, thus prevents the generation of flutter.
Pilot channel 53 is formed in the position of (more against the top than axis hole 51) against the top than the axis of rotation position of rotary shaft 16,
Pilot channel 53 is connected to the gas phase portion in discharge room 35a, and thus, it is possible to reliably supply to back pressure chamber 41 via pilot channel 53
To refrigerant gas, can promptly increase back pressure.
Pressure in discharge room 35a acts on restriction plate portion 63 via pressure supply hole 73.If the system in the 35a of room is discharged
The pressure of refrigerant gas rises, discharge room 35a and the pressure difference of back pressure chamber 41 become threshold value or more, then receives discharge room 35a
The restriction plate portion 63 of the pressure of interior refrigerant gas is bent, the bending deformation forwards of restriction plate portion 63.The restriction plate deformed
Portion 63 moves sphere 64 to close to the direction of back side panel 50.Sphere 64 is pressed to back side panel 50 by restriction plate portion 63, from
And as shown in fig. 7, sphere 64 is connected to back side panel 50, open and close valve 80 becomes closed state.In addition, Fig. 7 is to show by open and close valve
The cross-sectional view in the 80 pilot channels 53 closed.
If open and close valve 80 is closed, room 35a is discharged and pilot channel 53 becomes non-interconnected, become difficult to from discharge room
35a supplies refrigerant gas to back pressure chamber 41, and the back pressure supplied to back pressure chamber 41 becomes the lubricating oil supplied from reservoir compartment 35b.
