Abstract

PURPOSE:To prevent the useless power consumption of the scroll type compressor upon a low load by a method wherein a groove for a seal member is formed at the end face of the scroll body of a scroll member and a path introducing a pressurized fluid thereto through a control valve is provided. CONSTITUTION:A communicating hole 36 is communicated with the communicating hole 37 by operating the valve 38 by a control unit 39. The high pressure fluid, being introduced into the groove 32 of the seal member, is flowed to a low pressure side L through the communicating holes 36, 37. The seal member 34 is floating upper than the seal member groove 32 between A and B and is pushed against the disc 242 of the scroll member 24 opposing thereto, while the seal member 34 is adhered to the bottom of the seal member grooove 32 between A and C. Fluid in a small chamber 3b leaks out of the small chamber through a clearance c between the end face of the scroll body 252 and the disc 241 as shown by an arrow sign, therefore, the useless power consumption of the scroll type compressor upon the low load may be prevented.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a scroll compressor whose capacity can be controlled.

One type of compressor is a scroll compressor. This is done by interlocking a pair of thin rolls at different angles,
By giving them a relative circular motion (revolutionary motion only), the closed chamber formed in both the vortex chambers is moved toward the center, while the volume of the small il is decreased for 1-s, and the fluid inside Kotomi is reduced. This is the pressure position of the cylinder which compresses the fluid and discharges the compressed fluid from the center.

This kind of scroll shop's fluid machine O-hoori has been known for a long time. Figure 1 (→, (ke, (C),

In the figure, the center I8i surface of the conventional scroll pressure # machine constructed in this way is shown in Figure 2. 1so01-1 arrow section #i is shown in irises 3#A.

Hauling 10 of the compressor includes front end plate 1
1. It consists of a rear end plate 12 and a cylindrical side wall 13 (integrated with the rear end plate in the example shown) that connects the two, and communicates with the outside through a fluid outlet 14 and a fluid outlet 15 formed in the rear end plate 12. It is sealed at a shadow formation. The front end plate 1
A main shaft 17 is fixed to the main shaft 1, passing through the main shaft 1 and supported thereon for one rotation via a radial needle bearing 16f. A shaft seal mechanism 19 is installed around the main shaft 170 in a cylinder 18 that protrudes from the front end plate 11 at a distance of 70 mm from the main shaft 17. J-20 is supported by a bearing 9, and this pulley 20 is connected to the main shaft 17 to transmit rotational force from an external drive m (for example, a motor, etc.) to the main shaft 17 via a belt. There is.

A rotor 21 is fixed to the inner end of the main shaft 17.
It is supported by a thrust needle bearing 22 provided concentrically with the main shaft 17.

A shaft (crankbin) 23 that projects from the rotor 21 and is eccentric with respect to the main shaft 17 is provided on the opposite side of the rotor 21 from the 70-nt end plate 11 .

Reference numerals 24 and 25 designate a pair of scroll members, and the scroll member 24 has a spiral body 242 fixed to one side of a single six-plate 241, and a protrusion 2 having an axial round hole on the opposite side.
43 is formed, and this protrusion 243 is fitted with the radial needle bearing 26ti in its axial round plate. The @scroll member 25 supported by a bearing on the top has a thin winding body 252 fixed to one surface of a disc 251, and a kite 111I is placed on the disc 251 at a position approximately at the center of the spiral winding body 252. An X through hole 253 corresponding to the discharge port 4 inside is provided, and on the back side of the 1 yen f 252 is the through hole 253t-4! An annular protrusion 254 is provided so as to wrap around it.

On the other hand, an annular projection 121 is formed inside the rear end play (120) 111 from a position surrounding the fluid discharge port 15. The outer diameter of the protrusion 121 is slightly smaller than the inner diameter of the protrusion 254. The outer edge of the tip of the protrusion 121 is cut off to form an annular recess 9, which is connected to the inside of the annular protrusion 254 of the scroll member 25. An annular elastic body (for example, a rubber ring) 3G is arranged between the recess 122 and the recess 122. This annular elastic body 30 has annular protrusions 254 and 12
The inside of the annular protrusion 121 is sealed by the fluid outlet 1.
5 and a discharge chamber 311 communicating with the through hole 253 of the scroll member 25. The annular elastic body 30 elastically supports the scroll member 25 in the axial and radial directions. Regarding the scroll member 25, a notch is partially provided at the peripheral edge of the disc 2510, and the protrusion 131 protruding from the inner surface of the cylindrical side wall 13 is engaged with the notch to prevent (b) rolling of the scroll member 25. It is said that

With the above structure, if the main shaft 17 is rotated via the pulley 20 by the external drive #LK, the crankbin 2
Eccentricity II of 3! JK causes the scroll member 24 to move on a circular orbit. At this time, the rotation prevention mechanism 29 provided around the protrusion 2430 of the scroll member 24 prevents the scroll member 24 from rotating.
Function I of the scroll member 24 on the scroll member 25
It is the same as the Fill 1 figure, and as a result, the spiral body 242
, 252 is gradually compressed while moving to the center, and flows from the through hole 253 into the discharge chamber 311.
The fluid is discharged from the fluid outlet 15, circulates through the cooling system, and returns to the housing lO through the inlet 14.

The rotation prevention mechanism 29 of the scroll member 24 has the following structure. Protrusion of scroll member 24 @ 2
43 is connected to the crank body 27 so as not to rotate relative to each other. ◎The crank body 27 and the protrusion 5243 are connected to each other through the square tube @ 271 t-protrusion 243V in the center of the crank body 27. Here, the axial length of the crank body 27 including the rectangular tube is greater than or equal to the axial length of the scroll member 24. The thrust load applied to the rotor 21 is supported by the rotor 21 via a thrust needle bearing 28 provided between the crank body 27 and the rotor 21. A sliding body 291 having a rectangular outer shape and having a square diameter of 294 t is installed on the square tube portion 271 . As shown in FIG. 3, the square insert 294 of the lI moving body 291 has a pair of opposing sides that are the same size as a pair of sides of the rectangular tube part 271, and a pair of remaining sides that are larger than the other pair of sides. Also, the eccentricity P of the crank bin 23 with respect to the main shaft 17 is more than twice as large as the eccentricity P of the crank bin 23 with respect to the main shaft 17. This allows the rectangular tube portion 271 and the sliding body 291 to mutually slide in one direction.

A ring member 292 fitted with the sliding body 291 is installed around the sliding body 291, and the ring member 292
The cylindrical lit wall 1 of the housing 10 is opened by the key 293.
It is installed on the inner surface of 3 to prevent rotation. 8 295 at the center of the ring member 292 is included, and the pair of sides having the same dimensions as the pair of opposing sides of the outer shape of the sliding body 291 and the remaining pair of sides P also correspond to the eccentricity of the crank pin 23. pO2O
It has a rectangular shape consisting of a pair of long sides,
The sliding body 291 is guided so as to slide in a direction perpendicular to the sliding direction with the square tube part 271.Thus, the square tube part 271 can move in two directions orthogonal to each other, but is prohibited from rotating. Therefore, as a result of movement in two orthogonal directions, a trajectory on a circular orbit is created. Therefore, main axis 1
Due to one eccentric rotation of the crank bin 23 due to 70 rotations, the rectangular tube 5271 and therefore the scroll portion @24 revolve on a circular orbit without rotating.

In the scroll proof compressor mentioned above, JI
Figure 1 (!l) #3bO to the small W13 in the shape 11 shown in K
The $ side is the compressor on @ training amount, but this theoretical suction amount, that is, the theoretical discharge amount, is constant once the thin winding is determined.
I couldn't control this.

For this reason, for example, a vehicle g that drives the above-mentioned scroll lid pressure machine with a traveling engine! When used as a compressor for cooling and miscellaneous use, it is necessary to generate more than necessary refrigerating capacity during high-speed rotation, and at the same time, it requires more power consumption than necessary. A large load will cause problems such as a decrease in vehicle performance, poor driving feeling, and poor fuel efficiency.Also, when a Niscroll compressor is used, such as a so-called packaged air conditioner or a room air conditioner, KFi, It is easy to reach 1'm when the temperature inside the room is small, such as in the morning and evening, or in spring and autumn! 2! In order to solve the problem of generating the cooling capacity and consuming more power than necessary, the present invention has a method of extremely effectively reducing the general discharge volume. An object of the present invention is to provide a scroll compressor that can be controlled.

The present @O configuration of rounding that achieves the above purpose revolves around two scroll members each having +4& on the end face on the true side in the axial direction of the spiral body, with the phase shifted and in contact with each other. They are combined so that they can be moved in a circular manner, and a space is provided between the RAthll of at least one scroll member O spiral wound body and the end plate of the other star roll s@O, and a sealing material is formed on the end surface of the thin wound body of the scroll member. A sealing material is interposed therein so as to be movable relative to the sealing plate, and the sealing material is partially or completely covered over the entire length of the sealing material.
It is assumed that the pressure fluid that presses in the indicated direction is guided through the seal @flaK.

Hereinafter, a scroll compressor according to the present invention will be explained in detail with reference to an embodiment shown on the front page.

84m1 shows a cross section of the main part of one embodiment, which corresponds to 11$Ka of Fig. j12 showing the conventional one.

In addition, jIs- indicates the outside perspective of the scroll member.

Similar to the conventional O type, a disc (
A thin guard member 24 whose end ff1) 241 is attached, and one side of a thin wound body 252 having the same shape as the spiral body 242 (the opposite side of the spiral body 242 to which the disk 241 is attached) The compressor o*m#i is constructed by having the K disk (end plate) 251 and the attached spiral s25 shifted in phase by 1800 degrees and brought into contact with each other.

Scroll member 24, 250 spiral body 242°2520
Seal material $31.32 is provided on m1i. These sealing materials #1131.12 are applied to one scroll member 25.
As shown in Fig. 116, which represents fR outside the field of view, W1 is provided on the end face of the spiral wound body 252 from the medium heat sB of the spiral wound body 252 to the outside jliIsCK. , the ring is the sealing material @a1. az
A sealing material that is slightly smaller and more elastic (such as thiamin material)! 3,34 Kasuke is installed. Here, it is desirable to provide a gap 35 of KM 1,000 between the sealing material #32 and the sealing material 34 at the center of the spiral wound body 252, as shown in Fig. 5. The same applies to

Below), only the scroll member 25 on one side is addressed to the main address.
I will describe the configuration when it is accepted.

The scroll member 25 includes a communication hole 36 that is provided in the spiral body 252 and opens to the sealing material #132 and passes through the thin body 252, and a communication hole 36 that is connected to the wrinkle communication hole 36 and the circular plate 25.
A communication hole 37 passing through the inside of the compressor is provided.The communication hole 37 is left open to the low pressure power of the compressor. Also, the communication hole 36
There is a communication hole 36 at the point where it joins the communication hole 37 at the end of the
Piston (*
l! element) 38 is provided. This piston 3s is actuated by a control device 39. The degree to which the communicating hole 36 is provided in the hole III#i is determined according to the capacity to be controlled,
In this example, elementary school 113a in JII"1eEl
Specifically, the OA point corresponds to the A point in FIG. 5 when K is provided in the middle 1i of the part forming 3b (the part indicated by IExll middle figure).

As described above, sealing material #I31, 32 and sealing material 33
, 34, the distance t between them is equal to the height h of the spiral body 242 or 252.
The total value of 1,000 clearance C and
It will be 5 K s Clearance C will be provided and combined.The configuration of other parts in this v4 example is the same as the conventional one.

When the compressor is operated with the piston s8 closed to the communication hole 36t by the control device s9, the small chamber 3 formed near the center of the scroll member 24, 25 as described above with respect to the conventional one. The internal O pressure is low.@In this compressor, there is a slight gap between the seal material 34 and the seal punch 32 near the center of the spiral wound body 252.
bXTo#), from here the pressure fluid enters the sealing material 34 and the material @32 and O, so the sealing material $4 interposed in the seal [132 is 1 as shown in li4@IK.
The floating portion of the sealing material #32 is pressed against the opposing scroll member 240 and the disc 241. Therefore, due to the effect of this sealing material 34, the clearance C is virtually eliminated.1! F Closed Kotomi is formed in a stormy manner. Therefore, the compressor becomes a state where extremely smooth compression without leakage is performed continuously. KFi, Atsushi 6, changes the capacity of the compressor. As shown in the figure, the control device 39 operates the piston 38 to delay the passage of the communication holes 36 and 37. Sealing material #$3
High pressure fluid communication hole 36, 3 added in v'h
The low pressure side LK flows through the 7 pipes. Therefore, the seal @ 34 will be attracted to the seal cotton s20 bottom sK. However, since the communication hole 36 is provided with AAK in the stripe 5 figure, the spiral from point A Only the portion between the sealing material 54OAC on the outside of the sealing material *3240 is attracted to the bottom of the sealing material *3240. Rima D, mourning seal material with low pressure near point c-32
This is because only the AC lever becomes low pressure. On the other hand, the sealing material 34/ri of the AB jump located on the side of the Uzu SO Nakafu section from point A,
It floats up due to the high pressure fluid that enters the seal material #I 32 from the first seal 35 at point 8, or is attracted to the bottom of the seal punch 320 near point A.

Seal material 34u Seal material #32 at Konchi, Abbreviation B section
The disk 24 of the opposing scroll member 24 is lifted up further.
1, and in lIAcfM], the sealing material 34 is attached to the bottom of the sealing material #320. Therefore, between approximately AC, a clearance C is generated between jllFkJ of the spiral wound body 252 and the disk 241, as shown in Figure #I6, and the fluid confined within the small N3b flows to the outside of the small chamber as shown by the arrow. Further, between approximately A and B, the clearance C is substantially eliminated as in the case where the piston 38 closes the communication hole 36, and the small chamber 3
There is no leakage from b and 9 good compression occurs.

Next, the compression action by this compressor will be explained with reference to FIG. 1. When the communication hole 3Is is blocked and the sealing material 34 and the sealing material groove 32 are also lifted up, the small m3a.

3b is formed, and as mentioned earlier, the volume of the small chambers 3a, 3b in this state IIK is the theoretical suction amount 9, and good compression is continuously performed. On the other hand, when the piston 38 closes the communication hole 36, the sealing material 34 rises approximately between AB and sinks into the sealing material groove 32 between AC.
1(b), which is a 9G'-transformed version of this figure. At the small 1i[3b in the shape 11 shown by K, the fluid flows out from the clearance C to the outside. In this state, the two scroll members 24, 25C) each spiral body 242, 2521iil

]The first R(c) which comes to the center side is in the state shown by K.〈0 On the other hand, during this time, the small 3i[3b does not substantially suck in fluid. Since the sealing material 34 rises above the sealing material binding 32 at approximately point A, the small 113b is sealed at this position, and compression begins gradually.

a t) volume and the volume of the small chamber 3b in No. 111 (c) The theoretical suction amount is Il1 diagram ←) K$i-kuru 1
i13 (sum of volumes of a * 3 b)) is smaller than O. Thus, according to the scroll imaginary compressor of the present invention, it is possible to effectively change the theoretical suction amount.
l So-called effective capacity control of the compressor becomes possible. Therefore, the compressor can be operated in accordance with related equipment and surrounding conditions, and improvements in fuel efficiency can be achieved.

In the above embodiment, only one of the pair of scroll members 24, 250 has a variable capacity structure, but both may have a variable capacity structure. In this case, the small chamber 3 in Fig. 1-)
The volumes of both a and 3b can be changed.

In the above embodiment, one scroll member 25 is provided with one communication hole 36, but the number of communication holes 36 may not be one, but may be in multiple stages◇ In the above embodiment, A communication hole 36t was provided through the spiral body 252t'', but the communication hole 36Fi and the spiral body 252t

52 side mK communication hole 4o is provided, and a communication hole 36 opening in sealing material #1I32 is connected to this communication hole 40.

Furthermore, in the above embodiment, the sealing material binding 32 and the sealing material 34
The center s of the spiral body 252 has a structure for guiding high-pressure fluid between
In B, a gap 35 is provided between the sealing material 34 and the sealing material #I32, and the high-pressure fluid is introduced through the gap 35, but the structure is not limited to this, and various other structures are possible. As an example, in Figure JI & 8, the communication hole 36 is connected to the high pressure side H.
This shows one that can communicate with both the and low pressure @LO. In other words, the communication hole 41 that communicates with the communication hole 36 on the high pressure side HK.
A piston (valve element) 4 that connects the communication hole 42 communicating with the low pressure side LK and selectively removes them from the confluence point.

A high pressure of /d is applied to 32 from both the gap at point B of the center husband part of the spiral wound body 252 and from the communication hole 36 at point A, so that the sealing material 34 is better pressed against the mating disk 241. A good sealing effect can be obtained. Also, Iris 8PQ6))
As shown in the figure, when the piston 43 is connected to the right side K11tll: and the communication hole 36 is connected to the communication hole 42 leading to the low pressure @L, the same effect as in the example shown above is achieved, and the sealing material 84t!
It will be partially separated from the mating disk 241 ◎ Note that the low pressure or high pressure fluid applied to the communication hole 36 is the compressor production fluid (for example, nitrogen for a 9-air compressor, refrigerant for a refrigerant pressure koji machine). Used for 1 compressor for relaxation
It may also be a lubricating oil. In the first embodiment, as shown in FIG. 5, each of the sealing material #32 and the sealing material 34 is shown for one combination. Both do not need to be singular, they may be plural, and their shape can be arbitrarily determined. Figure 9 shows an example in which two seals 44 and 45 are provided.

The control device [39 is to cut off the communication with the low pressure or switch between the low pressure and the high pressure, through a communication hole in the seal punch, Alternatively, any structure may be used as long as it can apply and cut off arbitrary pressure (high pressure, low pressure, intermediate pressure if necessary) @ dS Patent Application No. 129196/1983,
As detailed in Japanese Patent Application No. 56-045600, the control device may be constructed by an unloader piston that operates when the low pressure falls below a certain value KfL, or as disclosed in U.S. Patent Application No. 56-100124. It may be a structure that operates by sensing 111 degrees of the suction refrigerant gas, as detailed in No. 1, or a fluid O device as detailed in Patent Application No. ISS&-253115. It will work. You can use the 5Qlj control device.
The valve may have a surface structure, such as a solenoid valve operated by an external signal, as shown in No. 9246. Furthermore, the control device may be one that applies the centrifugal force of the compressor. An example of the control device 39 is shown in Fig. 1θ. 50 is provided and pressed against the end of the communication hole 50 by the spring force of a ball bit spring 52. In addition, 53 is a retainer of the spring 52, and L is a low pressure space. When the rotation speed of the compressor is relatively low, the spring force of the spring 52 causes the ball 51 to move through the communication hole 50!
f! However, as the number of rotations increases, the centrifugal force acting on the ball 51 increases, and the ball 51
moves from the center of the communicating hole 50 to the outside, and the communicating hole 50 becomes the low pressure space LK! I:10. In this way, the control device 39 may be one that applies centrifugal force.
