Background technique
Usually, the compressor that constitutes motorcar air conditioner turns round by following steps: the restriction by magnetic clutch optionally receives driving power from power source, suck refrigerant gas from vaporizer, by the straight reciprocating motion compression refrigerant gas of piston, and refrigerant gas discharged towards condenser.This compressor is divided into all kinds according to compression method and structure, and has been extensive use of the variable conpacitance compressor that can change minimum cylinder volume in the middle of various types of compressors.
Fig. 1 is the sectional view according to the variable capacity swash plate type compressor of prior art.With reference to Fig. 1, comprise according to the variable capacity swash plate type compressor 1 of prior art: cylinder block 10, it has formation a plurality of cylinder-bore 11 within it; Front shroud 20, it joins the anterior of cylinder block 10 to and has formation crankcase 21 within it; Back cover 30, it is by plugging the rear portion that valve cell 40 joins cylinder block 10 between cylinder block 10 and back cover 30, and has suction chamber 31, drain chamber 32 and discharge passage 33.
Here, cylinder block 10 has suction ports 12 and suction muffler chamber 13, thereby by suction ports 12 and suction muffler chamber 13 refrigeration agent is introduced suction chamber 31.
In addition, live axle 50 is rotatably installed on cylinder block 10 and the front shroud 20, and thereby swash plate 60 is installed in the crankcase 21 by linking to each other with live axle 50 with articulated mounting 62 and rotate with live axle 50 by means of being fixedly mounted in rotating component 61 on the live axle 50, and changes the inclination angle accordingly with the variation in pressure of crankcase 21.
In addition, by on the periphery of swash plate 60, plugging hoof piece (shoe) 64 a plurality of pistons 65 are installed on the periphery of swash plate 60, are made piston 65 when in cylinder-bore 11, moving back and forth, suck and compressed refrigerant with matching with rotatablely moving of swash plate 60.
And, control valve 80 is being installed with the pressure difference between the gas pressure of the refrigeration agent swabbing pressure that changes cylinder-bore 11 and crankcase 21 on the back cover 30, thus the inclination angle of change swash plate 60.
In addition, in the drain chamber 32 of back cover 30, be furnished with vent silencer chamber 90 to reduce the fluctuation pressure of refrigerant emission.Vent silencer chamber 90 is included in the drain chamber 32 partition wall 91 that forms and is bonded to a side of partition wall 91 and has the lid 92 of refrigeration agent ostium 93.Therefore, the refrigeration agent that is disposed to drain chamber 32 from cylinder-bore 11 moves to vent silencer chamber 90 by the minor diameter refrigeration agent ostium 93 that forms at lid 92, is disposed to the outside by discharge passage 33 then.That is, by making the process that refrigeration agent expands, shrinks, expands successively through drain chamber 32, refrigeration agent ostium 93 and vent silencer chamber 90 time reduce fluctuation pressure.

And, because and the pressure difference between the swabbing pressure of the pressure of crankcase 21 and cylinder-bore 11 adjust the inclination angle of swash plate 60 accordingly, so the discharge capacity of compressor 1 changes.
Simultaneously, under the variable capacity swash plate type compressor 1 with no-clutch was installed in situation in the vehicle, when air conditioner was closed, compressor 1 kept minimum swash plate angle, but this angle does not become 0 degree, so air conditioner refrigerant emission when not turning round.In order to prevent above situation, in such compressor 1, use safety check 70.
Safety check 70 inserts and is installed in the discharge passage 33 of back cover 30 so that refrigeration agent circulates in compressor 1, and prevents that refrigeration agent is from external reflux when air conditioner is closed.
That is because safety check 70 only opens when the pressure that applies above predeterminated level, so when air conditioner does not turn round because at the minimum angle-of-incidence place of swash plate underpressure, this closure of check ring.When therefore, air conditioner does not turn round in the compressor 1 contained refrigeration agent can not be disposed to the outside but in compressor 1 circulation.
Yet, because safety check 70 is installed on the rear side (downstream side) of vent silencer chamber 90, so produced the pulsations of refrigerant emission.
In addition, be bonded to a side of partition wall 91 in drain chamber 32, to form vent silencer chamber 90, so increased the quantity of parts and the quantity of flow chart because must will have lid 92 additional knot of refrigeration agent ostium 93.
In addition, because safety check 70 must insert and be installed in the discharge passage 33 of back cover 30, thus must guarantee the installing space of safety check 70, thus the size of compressor 1 increased.

Simultaneously, between rotating component 161 and sleeve 163, compression helical spring 164 is installed so that swash plate 160 returns its initial position.
And, in drain chamber 132, form vent silencer chamber 180 to reduce the fluctuation pressure of the refrigeration agent that discharges.
That is, safety check 190 is installed on the refrigeration agent discharge passage of back cover 130 so that refrigeration agent circulates in compressor 100, and prevents to take place to introduce from the outside when air conditioner is in closed condition the backflow of refrigeration agent.In the present invention, vent silencer chamber 180 forms by safety check 190.
Therefore, the inboard that safety check 190 is engaged to partition wall 135 to be covering a side of vent silencer chamber 180, and the space of guaranteeing to be used for vent silencer chamber 180 is sentenced in the end that is positioned at partition wall 135 in this case.
Here, preferably safety check 190 is forced to the inboard that crimping is bonded to partition wall 135, and in this case, retainer 195 is installed on the internal surface of partition wall 135 is separated with partition wall 135 to prevent safety check 190.Simultaneously, at the arrangement pawl 135a that is formed with on the internal surface of partition wall 135 on the internal surface that is used for safety check 190 is placed in partition wall 135.
In addition, because safety check 190 is bonded to the partition wall 135 that is formed on drain chamber 132 central authorities,, thereby prevent from when the discharging high-pressure refrigerant, to occur fluctuation pressure waveform superposition phenomenon so safety check 190 also is installed in the central authorities of drain chamber 132.
As mentioned above, because vent silencer chamber 180 forms by safety check 190, so can save the parts (used in the prior art) that are used to form vent silencer chamber 90, thereby compressor 100 according to the present invention can reduce the quantity of the quantity of parts and flow chart and reduce fluctuation pressure (pulsations), and because safety check 190 is installed in the vent silencer chamber 180 that can guarantee the mounting zone, so safety check 190 can be installed under the situation of the size that does not increase compressor 100.
Valve body 192 has the cross section that forms " " shape, and is included in supporting claw 192b that is used for support elastic spare 194 that its central interior forms highlightedly and the flange 192c that forms at the outer circumferential face place of one side.
In this case, cap 191 and valve body 192 are engaged with each other by this way, that is: valve body 192 is inserted among beading (bead) 191b that forms highlightedly on the side of cap 191, and beading 191b bending is to surround the flange 192c of valve body 192.
When air conditioner is in closed condition, because keep the minimum angle-of-incidence of swash plate but it is not 0 degree, so even refrigeration agent is also to outside drain when air conditioner is in closed condition, but in this case, thereby because the very little underpressure of the discharge amount of refrigeration agent, so safety check 190 is not opened.That is because safety check 190 only opens when the pressure that applies above predeterminated level, so when air conditioner is in closed condition because in the minimum angle-of-incidence place of swash plate underpressure, safety check 190 is not opened.
Therefore, when air conditioner was in closed condition, compressor 100 can not be disposed to the outside with the refrigeration agent that wherein contains, but refrigeration agent is circulated within it and prevented the backflow of introducing refrigeration agent from the outside.
Refrigerant cycle process according to variable capacity swash plate type compressor 100 of the present invention hereinafter will be described.
At first, when the driving power of live axle 150 by motor rotates, the swash plate 160 that is installed on the live axle 150 is shaking along fore-and-aft direction in live axle 150 rotation, thereby repeats aspiration stroke and compression stroke when a plurality of pistons 165 that are bonded to the periphery of swash plate 160 move back and forth in the cylinder-bore 111 in cylinder block 110 successively.
Here, when piston 165 is carried out aspiration stroke, because open the suction valve (not shown) of valve cell 140 by the pressure drop of cylinder-bore 111, make cylinder-bore 111 and suction chamber 131 fluid communication with each other, so the refrigeration agent that is supplied to suction chamber 131 from the outside by suction ports 112 and suction muffler chamber 113 is introduced into cylinder-bore 111.
In addition, when piston 165 is carried out compression stroke, because compressed refrigerant by the supercharging of cylinder-bore 111, and thereby the escape cock (not shown) of opening valve cell 140 makes cylinder-bore 111 and drain chamber 132 fluid communication with each other, so compressed refrigerant is disposed to drain chamber 132 from cylinder-bore 111.
Next, the refrigeration agent that is disposed to drain chamber 132 is the refrigeration agent of High Temperature High Pressure, thereby opens safety check 190 by high-pressure refrigerant.When safety check 190 was opened, the refrigeration agent that is disposed to drain chamber 132 moved to vent silencer chamber 180 after passing refrigeration agent ostium 191a and refrigeration agent tap hole 192a, be disposed to the outside by discharge passage 133 then.
In this case, move to after refrigeration agent is passing safety check 190 during the process of vent silencer chamber 180, refrigeration agent expands in drain chamber 132, shrinks when passing safety check 190, in vent silencer chamber 180, reexpand, thereby reduced the fluctuation pressure of refrigerant emission.
Simultaneously, as mentioned above, when air conditioner does not turn round, thereby cause mobile less and pressure refrigeration agent of refrigeration agent less because the inclination angle of swash plate 160 is minimum, so safety check 190 cuts out, so refrigeration agent circulates in compressor 100.
As mentioned above, according to the present invention, because refrigeration agent circulated in compressor and prevent that safety check that refrigeration agent refluxes is installed on the side of vent silencer chamber with the form of lid when air conditioner be in closed condition, and the vent silencer chamber forms by this safety check, so described variable capacity swash plate type compressor can reduce the quantity of parts, the quantity of flow chart, and the fluctuation pressure (pulsations) of reduction refrigerant emission.
And described variable capacity swash plate type compressor makes safety check can be installed in the vent silencer chamber, and this has guaranteed to be used for the installing space of safety check and the size that can not increase compressor.
In addition, because safety check is positioned at the central authorities of drain chamber, so described variable capacity swash plate type compressor can prevent to occur fluctuation pressure waveform superposition phenomenon when the discharging high-pressure refrigerant.
In addition, described variable capacity swash plate type compressor can prevent in the drain chamber that safety check from separating by by means of retainer safety check being fixed on.
