Frictional resistance between spring sealing ring 130b and transfiguration cylinder 105b, improve displacement-variable device 130 action speed, reliability with
And service life.Sealing device can also use other forms sealing ring, such as O-ring seal etc..
In the course of work of screw compressor 101, orbiter 106 is driven to operate by drive part 103, orbiter 106
It is intermeshed with fixed scroll 105 so as to form crescent compression chamber.With the rotation of bent axle 113, refrigerant passes through air intake duct
107 enter the suction muffler of compression mechanism 102, and orbiter 106 is made to continue to turn round translation and remains good engagement,
Suction muffler is constantly elapsed to center, and volume is constantly reduced, and cavity internal pressure is constantly compressed；When compression reaches predetermined compression ratio
When, refrigerant is discharged by the center exhaust outlet of fixed scroll 105, into the upper space of housing 108, through fixed scroll 105 with
The exhaust passage of upper bracket 109 enters the lower space of the upper space of motor 104 and housing 108, motor 104 is cooled down, so
Screw compressor 101 is discharged by blast pipe 115.
When compressor makees the operation of full capacity state, as shown in figure 3, control unit 134 makes transfiguration control passage 133 and housing
Interior exhaust high-pressure channel 137 connects, and controls fluid guiding tube 131 to be vented gases at high pressure by throttling arrangement 135, by transfiguration and enters
Enter transfiguration cylinder 105b active sides, now downward active force Pd(pressure at expulsion) is more than upward directed force F, so as to promote master
Body piston 130a moves to by-pass prot 105a sides, meanwhile, elastic force of the piston protuberance 130e in the first elastomeric element 130d acts on
The lower by-pass prot 105a into fixed scroll 105, and piston protuberance 130e end face is bonded with the tooth top of orbiter 106,
By-pass prot 5a is closed by piston protuberance 130e, and now, middle pressure chamber is separated with suction muffler, and screw compressor is in full capacity fortune
Row state.
Using the Split piston, make piston that there is axial elasticity feature, part processing precision is wanted so as to reduce
Ask.Piston protuberance 130e end face and the peak contact of orbiter 106 in the presence of the first elastomeric element 130d in addition,
Sealing effectiveness is ensure that, if any 130a in impurity or burr piston protuberance 130e regracting main body pistons, plays avoidance effect,
Improve compressor reliability.
When screw compressor make varying capacity state operation when, as shown in figure 5, control unit 134 make transfiguration control passage 133 with
Suction pressure channel 136 connects, and the pressure of inspiration(Pi) gas for controlling fluid guiding tube 131 by transfiguration is made into transfiguration cylinder 105b
With side, now downward active force Ps(pressure of inspiration(Pi)) is less than upward directed force F, pressure difference and the second elastomeric element 130c to
The effect of upper elasticity, main body piston 130a are boosted, and piston protuberance 130e gushes the impact of refrigerant air-flow in by-pass prot 105a
Under be retracted into main body piston 130a, now, by-pass prot 105a open, so as to middle pressure chamber pass through by-pass prot 105a, transfiguration leak
Passage 105c connects with suction muffler, realizes and reduces screw compressor inspiratory capacity.
Under the percussion that by-pass prot 105a gushes air-flow, leakage path can change, and big flow refrigerant rushes down
Passage can voluntarily become big (gas shock piston protuberance 130e makes increase axial space in its retraction main body piston 130a) when going out,
Improve transfiguration efficiency.In the process, pressure and the relatively low by-pass prot 105a of temperature are arranged at because refrigerant leaks past, become
Hold leakage path 105c to connect with suction side, it is smaller to refrigerant heat degree, and raising screw compressor is in this condition
Aspirated volume efficiency is so as to improve performance of the screw compressor under transfiguration state, while the mechanism is arranged at the fixed scroll back of the body
It can avoid, because displacement-variable device causes the increase of compressor axial height, improving the compactedness of compressor arrangement in the substrate in face.
The invention further relates to a kind of air-conditioning system, including control unit 134 and the scroll compression of any of the above-described technical scheme
Contracting machine, control unit 134 connect transfiguration cylinder 105b, the also optionally exhaust end with the screw compressor of control unit 134
Or the suction end connection of the screw compressor, realize the screw compressor so as to control the displacement-variable device 130 to act
Capacity regulating.Air-conditioning system is prior art in addition to above-mentioned screw compressor and control unit 134, and air-conditioning is due to using above-mentioned
Screw compressor, same technique effect is also achieved, here is omitted.Wherein, control unit 134 and the screw compressor
Blast pipe 115 (exhaust end) between can also be arranged in series throttling arrangement 135, throttling arrangement 135 is electric expansion valve or hair
Tubule.
The screw compressor and air-conditioning system of various embodiments above, the piston in transfiguration cylinder use Split type structure so that
Piston has axial elasticity feature, improves screw compressor reliability, reduces the requirement to part processing precision.Bypassing
Hole is gushed under the percussion of air-flow, and leakage path is transformable, when big flow refrigerant gushes passage can voluntarily become it is big and
Improve transfiguration efficiency.Adjustable leakage path, solve the problems, such as that different refrigerant flows are gushed to leakage path size requirement.
Gas shock piston protuberance makes in its retraction main body piston, increases axial space.In the presence of the first elastomeric element, piston
The peak contact of protuberance and orbiter, ensure that sealing effectiveness, if any impurity or burr protuberance regracting main body piston
It is interior, avoidance effect is played, improves compressor reliability.Optimization to screw compressor, further ensure screw compressor appearance
The reliable adjustment of amount.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
