In the control valve 1 ' that adopts such structure, if to the excitation of switching on by coil 32, stator 33 and the solenoid part that attracts part 34 to form, then plunger 37 is furthered to attraction part 34, follow this action, valve rod 15 (closes the valve direction) upward by the bias force that closes valve spring 48 and moves.On the other hand, import to suck from compressor and to be pressed into mouthfuls 27 suction pressure Ps from importing the cannelure 37a of the periphery of chamber 23 by being formed at plunger 37,37a, ..., be formed at intercommunicating pore 39 grades that attract in the part 34 and import above-mentioned pressure-sensitive chamber 45, bellows main body 40 (inside is that vacuum is pressed) is corresponding to the pressure (suction pressure Ps) of pressure-sensitive chamber 45, carry out telescopic displacement (if suction pressure Ps is higher, then shrink, if suction pressure Ps is lower, then stretch), this displacement passes to valve rod 15 by actuating strut 14 and plunger 37, thus, adjust valve opening (lifting capacity of the relative valve port 22 of valve body 15a), in other words, the refrigerant flow that flows out from valve port 22.That is, refrigerant flow by by coil 32, stator 33 and attract suction, the bellows main body 40 of the plunger 37 of the solenoid part that part 34 forms bias force, open valve spring 47 and close the bias force of valve spring 48 definite.
Here, this time, if there are not the inaccessible parts 70 that have throttle orifice in supposition at refrigerant outlet 26 places, or the opening area of throttle orifice 71 is big fully, in other words, if control valve 1 ' is assumed to the control valve that the compressor that do not have clutch is used, then supply with the current value of coil 32 relatively, valve opening (lifting capacity of the valve port 22 of valve body 15a) follows current value to change from big to little variation and continuously (linearity), but, if current value be 0 or its near value, then the suction by the plunger 37 that attracts part 34 to take place diminishes, by opening the valve opening force of valve spring 47, valve rod 15 is depressed into lowering position (maximum lift position), valve port 22 standard-sized sheets (valve opening is maximum) quickly.Thus, the refrigerant flow that feeds to the crank chamber of compressor from the refrigerant outlet 26 in the downstream of valve port 22 increases (becoming peak rate of flow) quickly, and the pressure P c in the crank chamber of compressor rises sharp.
That is, current value is the territory, noncontrolled area near 0 zone.Even under situation with territory, above-mentioned noncontrolled area, problem does not take place in the compressor that does not have clutch, in having the compressor of clutch, if enter territory, above-mentioned noncontrolled area, then the pressure P c in the crank chamber surpasses permitted value, aspect control and configuration aspects produce and hinder.
Relative this situation, in the control valve 1 ' of present embodiment, because the inaccessible parts 70 that the throttle orifice 71 with regulation opening area is set are installed at refrigerant outlet 26 places, even so at valve port 22 standard-sized sheets, or be opened under the situation near standard-sized sheet, the peak rate of flow of refrigeration agent of crank chamber of supplying with compressor is no more than the allowance in the compressor that has clutch by throttle orifice 71 and throttling is restricted.In this occasion, if supply with the current value of coil 32 and be 0 or near 0 value, then as aforementioned, by the valve opening force of opening valve spring 47 valve rod 15 is pressed down, but this moment, because the refrigerant flow of the crank chamber of supply compressor is by above-mentioned throttle orifice 71 throttlings, be restricted, so the pressure in the above-mentioned refrigerant outlet (chamber) 26 rises, the rate of descent of valve rod 15 (valve body 15a) is slow, by the also increase sharp of refrigerant flow of valve port 22.
Like this, in the control valve 1 ' of present embodiment, even at valve port 22 standard-sized sheets or be opened under the situation near standard-sized sheet, peak rate of flow throttling of the refrigeration agent of the crank chamber of supply compressor by the throttle orifice 71 of inaccessible parts 70, be restricted, be no more than the allowance of the compressor that has clutch, thus, can be used for having the compressor of clutch, in addition, because can add the throttle mechanism of inaccessible parts 70 grades that have throttle orifice in the control valve that the compressor that does not have clutch is used gets final product, so produce the compressor do not have clutch with and both occasion of control valve that has that the compressor of clutch uses, but common component is more than half, manufacture cost can be suppressed at than low degree.
(the 3rd embodiment)
The 3rd embodiment to control valve for variable capacity compressor of the present invention is described below.
The control valve 1 of present embodiment " basic structure (Fig. 6) identical with above-mentioned the 2nd embodiment's control valve 1 '; difference is limiting valve aperture " the lifting capacity L (with reference to Fig. 7) of the valve port 22 of valve body 15a ", so that suppress the variation as the pilot pressure gradient (with reference to Fig. 8) of the inaccessible parts 70 that have throttle orifice of throttle mechanism.
Below it is specifically described.
By being provided as the inaccessible parts 70 that have throttle orifice of throttle mechanism, shown in the dotted line in the image pattern 8 like that, if the current value of supplying with coil 32 less than near 0 Ia (such as, 0.1A) (entering the territory, noncontrolled area), valve opening (lifting capacity L) maximum then, or near maximum, but, because peak rate of flow throttling of the refrigeration agent of the crank chamber of supply compressor by the throttle orifice 71 of above-mentioned inaccessible parts 70, be restricted, so the force value Qa when supplying with the above-mentioned relatively current value of pressure P c of the crank chamber of compressor and being Ia does not almost change.
Relative this situation, (such as, 0.1A) Yi Shang control area, pressure P c's current value at leisure that follow supply coil 32 diminishes to big variation from little, and the pilot pressure gradient is θ ' at above-mentioned Ia at the current value of supplying with coil 32.
But the pilot pressure gradient that requires as the control valve for compressor that has clutch is such θ shown in the solid line among Fig. 3 (θ＞θ ').This pilot pressure gradient θ is not for being provided with the occasion of throttle mechanism (the inaccessible parts 70 that have throttle orifice), promptly, the pilot pressure gradient of above-mentioned control area of state that does not have the control valve for compressor of clutch, the pilot pressure gradient θ ' of occasion that throttle mechanism is set is less than the pilot pressure gradient θ of the occasion that throttle mechanism is not set.Therefore, the pressure P c control range of occasion (D ') of throttle mechanism is set less than the occasion that throttle mechanism is not set (D).
It is believed that the reason of like this, diminish by throttle mechanism pilot pressure gradient is set (θ → θ ') is because of having throttle mechanism (the inaccessible parts 70 that have throttle orifice), in the inner product pressure accumulation power (pressure rising) of refrigerant outlet (chamber) 26.In this occasion, valve opening (lifting capacity) and to have the big more influence of difference of aperture φ (opening area=throttle opening) of throttle orifice 71 of inaccessible parts 70 of throttle orifice big more.In addition, if in the inner product pressure accumulation power (pressure rising) of refrigerant outlet (chamber) 26, then the power of the direction of cut-off valve body 15a (valve closed force) also increases.
Therefore, in the present embodiment, the aperture φ (opening area=throttle opening) of throttle orifice 71 that will have the inaccessible parts 70 of throttle orifice is chosen to be the size that the valve on-off action is not caused adverse effect, and limiting valve aperture (lifting capacity L), promptly, valve opening (lifting capacity L) is compared with the 2nd embodiment less than the 2nd embodiment, further to carrying out throttling control from valve chamber 21 by the refrigerant flow that valve port 22 exports to refrigerant outlet (chamber) 26.
Specifically, the aperture φ of throttle orifice 71 that has the inaccessible parts 70 of throttle orifice is set in the scope of 1.2～1.3mm, and maximum lift amount is in the scope of 0.15～0.25mm.At will say, in the 2nd embodiment, above-mentioned aperture φ such as, be set at 4.9mm, in addition, maximum lift amount is such as being 0.65mm.
Control valve for variable capacity compressor 1 in the 3rd embodiment who constitutes like this " in; because restriction lifting capacity L; so that suppress the variation of the pilot pressure gradient of throttle mechanism (the inaccessible parts 70 that have throttle orifice); so shown in the solid line among pilot pressure gradient and Fig. 8, desired θ is basic identical as the control valve for compressor that has clutch.Thus, by throttle mechanism (the inaccessible parts 70 that have throttle orifice), the peak rate of flow of the refrigeration agent of the crank chamber of supply compressor, simultaneously, can substantially fully satisfy the control valve desired control characteristic that the compressor that has clutch is used, in addition, equally in the present embodiment, because can be only in the control valve that the compressor that does not have clutch is used, the throttle mechanism that adds inaccessible parts 70 grades that have throttle orifice gets final product, so produce the compressor do not have clutch with and both occasion of control valve that has that the compressor of clutch uses, but common component is more than half, manufacture cost can be suppressed at than low degree.
In addition, in the above-described embodiments, adopt the inaccessible parts 70 that 1 throttle orifice 71 is set as throttle mechanism, but be not limited to this, can be such as in inaccessible parts, forming a plurality of throttle orifices, set the number of throttle orifice, the various forms of the size shape of each throttle orifice etc. according to these total opening areas less than the mode of the maximum actual effective vent area of valve port.
