One end of the spring is abutted with the adjustment piston, and the other end is butted by the flange fixed at the other end of the barrel body. The air outlet pipe is connected with the flange, and the air inlet pipe and the air outlet pipe are respectively connected with the air inlet and the air outlet on the shell of the compressor.
Description
The utility model relates to a kind of compressor, particularly a kind of varying capacity scroll compressor.
The varying capacity scroll compressor is applied on the car air conditioner, and is applying to aspect the room air conditioner.The variable capacity control mechanism of existing varying capacity scroll compressor all is arranged on compressor inside, this compressor is usually by housing and protecgulum thereof, moving scroll, fixed scroll and bent axle are formed, its control mode is to adopt the mode of pressure to regulate, and its sensitivity and reliability are not very good, remain further to be improved, and because variable capacity control mechanism, keeps in repair also inconvenience in inside.
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of sensitivity and reliability the varying capacity scroll compressor with flow control better and easy to maintenance.
Technical solution of the present utility model:
A kind of varying capacity scroll compressor with flow control, it includes by housing and protecgulum thereof, moving scroll, the scroll compressor body that fixed scroll and bent axle are formed, it is characterized in that suction port and relief opening on the housing of compressor block are connected with externally connected type varying capacity device by conduit, and the varying capacity device is installed on the housing, this varying capacity device is by cylindrical shell, regulating piston, spring, suction tude, steam outlet pipe and flange are formed, suction tude and cylindrical shell one end are connected, regulating piston is loaded in the cylindrical shell, spring one end withstands regulating piston, the flange that its other end is fixed on the cylindrical shell the other end props up, steam outlet pipe links to each other with flange, and suction tude is connected on the relief opening of compressor housing, and steam outlet pipe is connected on the suction port of compressor housing.
The utility model is arranged on the outside of compressor with the variable capacity control mechanism of varying capacity scroll compressor, its manufacturing and installing easily, and cost reduces, and working sensitivity and reliability further improve, and keep in repair convenient.After the utility model is applied on the air-conditioning system, can make the refrigerating capacity of air-conditioning system not be subjected to the influence of engine speed change, thereby keep car, room temperature constant.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a compressor arrangement schematic representation of the present utility model;
Fig. 2 is the structural representation of the utility model varying capacity device.
As Fig. 1,2, the utility model includes by housing 1 and protecgulum 2 thereof, moving scroll 3, the scroll compressor body that fixed scroll 4 and bent axle 5 are formed, characteristics of the present utility model are, suction port 6 on the housing 1 of compressor block and relief opening 7 are connected with externally connected type varying capacity device 8 by conduit, and varying capacity device 8 is installed on the housing 1, this varying capacity device 8 is by cylindrical shell 9, regulating piston 10, spring 11, suction tude 12, steam outlet pipe 13 and flange 14 are formed, suction tude 12 is connected with cylindrical shell 9 one ends, regulating piston 10 is loaded in the cylindrical shell 9, spring 11 1 ends withstand regulating piston 10, and the flange 14 that its other end is fixed on cylindrical shell 9 the other ends props up, and steam outlet pipe 13 links to each other with flange 14, suction tude 12 is connected on the relief opening 7 of compressor housing 1, and steam outlet pipe 13 is connected on the suction port 6 of compressor housing 1.
In the utility model, seal ring 15 is housed on regulating piston 10, sealing ring 15 as close as possible suction tude 12 1 sides, it is used for stoping pressurized gas to reveal to low voltage side.Have cascading water shallow slot 16 in the inboard of cylindrical shell 9, the sectional area of this cascading water shallow slot 16 is linear change, and is big more the closer to steam outlet pipe 13 sectional areas.When the gas pressure of the relief opening 7 of compressor surpasses setting value, regulating piston 10 is opened cascading water shallow slot 16, the part pressurized gas return compressor inlet 6 through cascading water shallow slot 16, and it is many more that the gas pressure of relief opening 7 surpasses setting value, the area of opening cascading water shallow slot 16 is big more, and the cascading water ability is strong more.The on high-tension side end of cascading water shallow slot 16 distances is distal to the position at nominal situation lower sealing ring 15 places, is bordering on the position of varying capacity device 8 work operating mode lower sealing rings 15.
Working principle of the present utility model is as follows, and the fixed scroll 4 of scroll compressor body is fixed in housing 1, and moving scroll 3 is fastened in the fixed scroll 4, and protecgulum 2 is supporting bent axle 5 and eccentric bushing, and bent axle 5 and eccentric bushing drive moving scroll 3 by the certain track motion.The vortex wall of dynamic and static scroll 3,4 is radially being worked in coordination with angle, has formed snag contact, thereby has determined an enclosed cavity at least.Along with the motion of moving scroll 3, the enclosed cavity volume reduces the relief opening 7 of also close compressor gradually, and intracavity gas is discharged by relief opening 7 by compression at last.Bent axle 5 rotating speeds are high more, and the chamber number that the unit time is finished compression is many more, and air displacement is big more, and exhaust pressure is high more.When pressure reached certain value, regulating piston 10 was opened cascading water shallow slot 16, and the part pressurized gas return compressor inlet 6 through cascading water shallow slot 16, and pressure is high more above setting value, and it is big more that cascading water shallow slot 16 is opened, and the pressurized gas that return are many more.Thereby realized being defeated by the gas flow substantially constant of air-conditioning system.
