Piston shoes 19 are placed on each interarea of the wobbler between the sliding surface of each piston shoes 19.Piston shoes 19 have spherical, the curve opposite surfaces.The interarea of wobbler 10 peripheries slides along the sliding surface of piston shoes 19.As shown in Figure 1, a pair of piston shoes 19 are this forms, and promptly its positive camber forms and has the sphere that radius is approximately R.Being centered close on the plane of dividing wobbler 10 equally of sphere, the center that is to say sphere are the centers of wobbler 10 thickness.The piston rod 20 that one one end has prong blocks the piston shoes between it and the wobbler 10.A piston 21 is placed on the other end of (or integrally extending to) piston rod 20, and is slidably received among the cylinder chamber 2a.Several this piston rods and paired piston shoes are set in compressor.
Be formed with the exhaust port that is used to import the suction port 22 of liquid and is used for drain on valve plates 24, a side of valve plates 24 is connected with cylinder block 2 by packing ring 25; The opposite side of valve plates 24 is connected with cylinder head 26 by packing ring 29.The next door 26a of cylinder head 26 is separated into cylinder head 26 suction chamber 27 and discharges chamber 28.Cylinder baffle 1 is by valve plates 24 that is connected in cylinder block 2 tops and cylinder head 26 cappings.Suction passage 27a is used for to suction chamber 27 input medias; Discharge route 28a is used for discharging medium from discharging chamber 28.Form a through hole 30 that is used to be communicated with crankcase 1a and suction chamber 27 in the cylinder block 2.Path 30 comprises: a through hole 30a who runs through valve plates 24, and packing ring 25 and 29, and the port hole 30b of bellows 34 is equipped with in inside.
Pipe coupling joint 31 with through hole 31a and valve base 31b faces crankcase 1a and is placed in the through hole 30b.Between pipe coupling joint 31 and cylinder block 2, embed an O-RunddichtringO 32 in case the fluid stopping body leaks.The base 33 that has through hole 33a in the both sides, top is fixed among the through hole 30b.The bellows 34 that the end has a thimble 34a is placed on the surface of base 33 and is filled with the gas of certain pressure in bellows 34.When the top of thimble 34a was inserted among the through hole 31a, through hole 31a was just sealed by the valve base 31b of thimble 34a and pipe coupling joint 31.
See figures.1.and.2, represented the above-mentioned operational situation that is used for the compressor of cooling cycle system among the figure.
When the rotatory force rotating driveshaft by driving source input, this rotatory force partly passes to wobbler 10 by rotor 8 and hinge, and wobbler 10 is rotated.Yet this rotational motion is not delivered on the piston rod 20, and when wobbler 10 rotated, the interarea of wobbler 10 slided on a pair of sliding surface of facing of piston shoes 19, and piston rod 20 is exactly to be connected to by this way on the piston shoes 19.That is to say the not motion of the above-below direction in these figure of piston 21.Therefore, the rotatory force of wobbler 10 has become the motion of piston 21 to-and-fro motion of left and right directions motion in these figure.Because the to-and-fro motion of piston 21, compress thereby the liquid that sucks from suction port 22 is pressed into the cylinder chamber 2a, and by tap hole 23, liquid is discharged to discharge in the chamber 28 goes.
Can change the compression volume of compressor with following method.In air-conditioning system, when air conditioning load was higher than the load of predetermined temperature, then refrigeration capacity was just inadequate, and it is higher that the incoming pressure of refrigeration will become, and made the pressure in the input chamber 27 become very high.Therefore, with the input port hole 30b that is communicated with of chamber 27 in pressure also will become very high.
The gas that is arranged in the bellows 34 of port hole 30b seals by this way, that is: in refrigeration system, the gas in the bellows 34 is a bit higher than the incoming pressure corresponding to predetermined temperature slightly.Therefore, when air conditioning load was higher than the load of predetermined temperature, bellows 34 was towards as shown in Figure 1 right-hand contraction, and thimble 34a removes from valve base 31b, opens through hole 31a with this.Like this, suction chamber 27 just has been communicated with crankcase 1a.Because the gas that leaks into crankcase 1a owing to the work of compressor is got back to suction chamber 27, then the pressure among the crankcase 1a becomes almost and to equate with pressure in the suction chamber 27.
In this case, when carrying out the compression cycle process, by being in the corresponding wobbler 10 equal angles pressurized air reaction force acts that piston action produced spaced apart on wobbler 10, and act on thus on the above-mentioned hinge part.Owing to the reaction force that acts on the piston 21 produces moment M 1, this moment M 1Act on its clockwise direction is rotated.Because the rebounding force that helical spring 12 produces produces moment M 2; Also owing to the pressure difference between crankcase 1a and the suction chamber 27 has produced moment M 3Therefore, when through hole 31a opens, make in crankcase 1a and the suction chamber 27 not have pressure difference, thereby have only moment M 1Resistant function moment M 2So, if be provided with helical spring 12 to such an extent that make moment M 1Greater than M 2, wobbler 10 just moves and pushes to around the pin turning handle pin 11 of hinge bindiny mechanism the upper end portion of elongated hole 8b to rotor 8 so.At this moment, the relative vertical surface in the tilt angle of wobbler 10 is maximum.Thereby the piston 21 that causes being among the cylinder 2a that is equivalent to the normal refrigerating volume of compressor has maximum stroke.
When air conditioning load is low, and compressor operation speed is very high, and it is very big that the compression volume of compressor will become.Therefore, the pressure in the suction chamber 27 will reduce, and bellows 34 moves to left and makes thimble 34a close through hole 31a.This state as shown in Figure 2.In this case, because gas leakage, the pressure of crankcase 1a increases gradually, produce a pressure difference, in compression stroke, the leakage of this gas is to leak to crankcase 1a from cylinder chamber by the slit between piston and the cylinder, and collects among the crankcase 1a.In the process that pressure raises in crankcase 1a, produce moment 3 and its increasing amount increasing amount corresponding to pressure among the crankcase 1a.Moment M 3React on moment M 1, therefore in some aspects, moment M 2With moment M 3Total amount surpass moment M 1When this happens, produce in the hinge bindiny mechanism around pin 11 counterclockwise the moment loadings of effect on wobbler 10, make wobbler 10 reduce with respect to the angle of inclination of vertical plane.The tilt angle continues to reduce till pin 11 and slotted hole 8b underpart offset.Because the tilt angle reduces, the stroke of piston will reduce and the capacity of compressor reduces gradually among the cylinder 2a.Because if the complete stop motion of piston, then flowing of refrigerant gas and lubricant oil also can stop (motion of piston can be kept compressor and lubricate with keeping), do not stop fully so do not wish the motion of piston.
The length that is in the slotted hole 8b of hinge part determines by this way according to the compressor compresses capacity, promptly the minimal compression capacity of compressor should be its maximum compression capacity 35 20 percent to percent between.
With reference to Fig. 3 (a), it has represented the bindiny mechanism of existing piston and wobbler.The hemisphere piston shoes 19 that have radius and be B are placed on two sides of wobbler 10, and the thickness of wobbler is t, and the distance A between two piston shoes, 19 spheres is determined by following formula (1):
A＝2B+tx 1/(cosα) （1）
α represents the angle between vertical axis and wobbler 10 medial axis.
Just as described above, because the tilt angle varied of wobbler 10, the interhemispheric distance represented by formula (1) also changes along with the tilt angle of wobbler 10.Yet, both made the retained part 35 of distance A between the two hemispheres and piston rod 20 ' between the equal in length of distance C, shown in Fig. 3 a, because interhemispheric distance A changes along with the tilt angle of wobbler 10, and on the other hand, retained part 35 ' between distance C constant, therefore, shown in Fig. 3 (b), between piston shoes 19 and wobbler 10, produce the gap, make the piston 21 can not smooth sliding.
In addition, as shown in Figure 4, each piston shoes 19 according to the present invention has and the opposite garden sphere of sliding surface of facing wobbler 10.A pair of piston shoes 19 are settled by this way round the principal plane of wobbler 10, the outer spherical surface that is piston shoes is that the garden sphere of R limits by radius substantially, and the centre of sphere is arranged in a bit the going up of face D of wobbler 10, and (this face D is divided equally into two equal parts to wobbler 10 between the principal plane outside two of wobbler 10.Two interhemispheric distance A do not change along with the tilt angle of wobbler 10, but keep equating.Therefore, can not produce the gap between piston shoes 19 and wobbler 10, piston 21 is always worked reposefully.
The present invention is described in detail in conjunction with optimum implementation, but this is some examples, the present invention is not limited to this.Understand easily, all engineers and technicians that are familiar with this technical field all can conceive range content in the present invention and change places and carry out various changes and improvements.
