In addition, front case 120 is rotatably passed in an end of live axle 150, and the other end is inserted into the center of cylinder block 110 in the mode that is rotatably supported.
And rotor 160 is attached on the live axle 150 in crankcase 121, thereby with live axle 150 rotations.
In addition, wobbler 170 is rotatably installed on the sleeve 165, this sleeve 165 combines with live axle 150 in crankcase 121 slidably, wobbler 170 by crawler shoe 145 being plugged piston bridge fitting 141 the insertion space and wobbler between its edge rotatably is installed to insert the space, thereby and by articulated mounting 175 with rotor 160 connect with rotor 160 rotations in adjust its inclination angle with respect to live axle 150.
Here, wobbler 170 comprises the wobbler plate 172 that rotatably is attached to the hub 171 of sleeve 165 and is attached to the outer surface of hub 171 by hub pin 166, and its middle sleeve 165 combines with live axle 150 slidably.
In addition, be used for rotor 160 and wobbler 170 articulated mountings 175 connected to one another are comprised and be formed on rotor 160 1 sides and have first articulated jib 161 of groove 162 and be formed on wobbler 170 1 sides and have second articulated jib 171 of the swivel pin 172 that movably combines with the groove 162 of first articulated jib 161.
In addition, valve cell 180 is installed between cylinder block 110 and the rear case 130, during the suction stroke of piston 140, refrigeration agent being drawn into the cylinder-bore 111 from induction chamber 131, and during compression stroke, refrigerant compressed is discharged into the exhaust chamber 132 from cylinder-bore 111.
Simultaneously, control valve 190 is installed in the rear case 130 and makes exhaust chamber 132 and crankcase 121 is operated fluid each other and is communicated with, thereby change poor between refrigeration agent suction pressure in the cylinder-bore 111 and the gas pressure in the crankcase 121, can adjust the inclination angle of wobbler 170 whereby.
And, elastic component 155 is installed on the live axle 150 between rotor 160 and the wobbler 170, and have and be used on the rotation centerline of wobbler 170 promoting the spring portion 156 of wobbler 170 and be formed on the reverse inclination portion 157 that promotes wobbler 170 with the position of the rotating center of wobbler 170 (d) spaced a predetermined distance from and the direction that is used for reducing along the inclination angle, when changing the inclination angle of wobbler 170, make a side of elastic component 155 closely contact rotor 160 all the time whereby, to prevent the vibration of wobbler 170.
That is to say, as shown in Fig. 5 and Fig. 6, the power (F1) that will be used for promoting along the direction that is parallel to live axle 150 wobbler 170 is applied to spring portion 156, and will be used for being applied to the reverse inclination portion 157 that is positioned at the position of the rotating center of wobbler 170 (d) spaced a predetermined distance from along the power (F2) that the direction (downward direction) perpendicular to live axle 150 promotes wobbler 170.Therefore, spring portion 156 makes wobbler 170 get back to initial position, and the direction that reverse inclination portion 157 reduces along the inclination angle promotes wobbler 170.
Simultaneously, Fig. 7 represents the serviceability of reverse inclination portion 157.In Fig. 7, reverse inclination portion 157 is positioned at diverse location when wobbler 170 is in maximum angular and minimum angle.That is to say, when wobbler 170 is in maximum angular, raise and the position that produced elastic restoring force begins from reverse inclination portion 157, the direction that reverse inclination portion 157 reduces along the inclination angle when the inclination angle according to wobbler 170 changes its position all the time promotes wobbler 170.
And reverse inclination portion 157 can be configured to following two types.
At first, as shown in Figure 4, reverse inclination portion 157 comprises the supporting portion 158 on the end that is integrally formed in spring portion 156, is used for a side of direct supported swashplate 170.
Here, preferably, supporting portion 158 radially extends to predetermined length along wobbler 170.
Secondly, as shown in Figure 8, reverse inclination portion 157 and the mode slidably combination of live axle 150 between spring portion and wobbler 170, and the supporting portion 158a that comprises spring section 159 and be used for direct supported swashplate 170 1 sides to separate with spring portion 156.
As mentioned above, integrally formed or separately be formed on reverse inclination portion 157 in the spring portion 156 and be subjected to elastic force from spring portion 156, and promote wobbler 170 in the direction that is not having tight contact sleeve 165 but directly closely reducing along the inclination angle in the hub 171 of contact wobbler 170.
That is to say, because wobbler 170 rotatably is attached to sleeve 165 by hub pin 166, this sleeve combines with live axle 150 slidably, so wobbler 170 can the inclination angle increase or all directions of reducing on unrestricted motion, and in this case, reverse inclination portion 157 is promoted wobbler 170 by elastic support with the direction that reduces along the inclination angle.
Therefore, be at compressor 100 under the situation of maximum angular, the inclination angle of wobbler 170 increases and spring portion 156 is gradually reduced.In this case because 157 directions that reduce along the inclination angle of reverse inclination portion apply elastic force to wobbler 170 constantly, so swivel pin 174 in a side of the tight close rotor 160 of contact wobbler 170 in groove 162 persistent movement.
On the contrary, be at compressor 100 under the situation at minimum angle, reduce the inclination angle of wobbler 170 by the restoring force of spring portion 156, and in this case, because 157 directions that reduce along the inclination angle of reverse inclination portion apply elastic force to wobbler 170 constantly, thus swivel pin 174 in a side of the tight close rotor 160 of contact wobbler 170 in groove 162 persistent movement.
Simultaneously, wobbler 170 has on the side that is formed on hub 171 and is used to support the retainer 176 of reverse inclination portion 157.That is to say,, on live axle 150, rotate so can prevent reverse inclination portion 157 because the supporting portion 158 of reverse inclination portion 157 or 158a settle and stably be supported on the retainer 176.
As mentioned above, reverse inclination portion 157 one or be installed in dividually on the end of spring portion 156, hub 171 with direct elastic support wobbler 170, thereby the direction that reduces along the inclination angle promotes wobbler 170, whereby owing to swivel pin 174 when changing the inclination angle of wobbler 170 rotates under the state of its tight contact groove 162 sides all the time, so the present invention can prevent the noise of the vibration and the generation of wobbler 170 in the operation period of compressor 100.
Simultaneously, even when assembling wobbler 170, between swivel pin 174 and groove 162, have spacing, owing to reverse inclination portion 157 is subjected to having reduced this spacing from the elastic force of spring portion 156, so the present invention can reduce vibration and noise.
In addition, as mentioned above, because swivel pin 174 only with under the tight state of contact in groove 162 sides is rotating all the time, so as shown in Figure 9, can remove swivel pin 172 from the groove 162 of first articulated jib 161 and not have the closely part of contact, thereby the present invention can guide the inclination angle of wobbler 170 under the situation that does not form groove 162, thereby simplifies the structure and reduced manufacture cost.
And, if remove groove 162, also remove swivel pin 174, and in this case, the present invention can have such structure, and second articulated jib 173 that wherein is formed on the hub 171 directly is directed to the inclined surface that is formed on first articulated jib 161 on the rotor 160.
