Description
Technical field
The unidirectional fixed displacement oblique tray type compressor of the utility model belongs to the air condition compressor field.
Background technique
The piston-type automobile air-conditioning compressor of existing fixed discharge capacity generally includes two kinds of bi-directional swash plate type and unidirectional wobble plate types, bi-directional swash plate type compressor drives the swash plate rotation that is fixed on the main shaft by main shaft, piston hangs on the swash plate by slip hemisphere, when rotating, swash plate drives moving linearly in the piston cavity of piston on front-bank rotor housing and rear-bank rotor housing, at front-bank rotor housing one group of suction and discharge assembly is arranged, one group of suction and discharge assembly is arranged at rear-bank rotor housing.Bidirectional piston formula compressor is little and be widely used with its volume, but because it be a bidirectional piston, total number of cylinders at double is not suitable for little capacity compressors, and the bidirectional piston difficulty of processing big, have two overlap the suction and discharge assemblies, cylinder body has increased product cost.
Unidirectional wobble plate type compressor drives the shaking tray rotation that is fixed on the main shaft by main shaft, the planet plate waves under the promotion of shaking tray, the connecting rod that is connected with the planet plate is connected piston with the planet plate, along with waving of planet plate, drive piston and in the piston cavity of cylinder body, do straight reciprocating motion, one group of suction and discharge assembly is installed at cylinder body.Unidirectional wobble plate type compressor arrangement complexity, many, the poor reliability of part, main is the structure that its piston adopts piston ring, increases frictional resistance, has strengthened the energy consumption of compressor.
Summary of the invention
The purpose of this utility model is to avoid deficiency of the prior art, and cost is low, volume is little, help being applied on the little capacity compressors the unidirectional fixedly oblique tray type compressor that structure is simpler, reliability is high, energy consumption is low.
The purpose of this utility model reaches by following measure, it is by swash plate, cylinder body, exhaust valve plate, air aspiration cavity, piston cavity, exhaust cavity, valve plate, suction valve chip, hemisphere, piston, main shaft is formed, and main shaft is installed on the cylinder body, and swash plate is installed on the main shaft, hemisphere is installed on swash plate, piston is installed on the swash plate by hemisphere, and cylinder body is provided with one group of suction and discharge assembly, and the suction and discharge assembly is by suction valve chip, valve plate, exhaust valve plate, diaphragm seal is formed, piston cavity communicates with air aspiration cavity by suction valve chip, and air aspiration cavity communicates by the sucking pipe of intakeport with the outside.Piston cavity communicates with exhaust cavity by exhaust valve plate, and exhaust cavity communicates with outside outlet pipe by relief opening.
The circumferencial direction of the utility model main shaft can be arranged a plurality of pistons, and another part piston is in exhaust when a part of piston is air-breathing, and in the process that swash plate rotates a circle, all pistons are finished suction and discharge circulation.
The utility model can be coated with the polytetrafluoroethylmaterial material coating on the circumference of piston.
Piston of the present utility model can adopt box type piston.
The utility model is simple in structure, saves cost, and volume is little, help being applied on the little capacity compressors, and the reliability height is saved the space.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: swash plate 4, cylinder body 6, exhaust valve plate 7, diaphragm seal 8, relief opening 10, air aspiration cavity 12, intakeport 13, piston cavity 14, exhaust cavity 15, valve plate 16, suction valve chip 17, hemisphere 20, piston 21, main shaft 23.
As shown in Figure 1, the utility model is by swash plate 4, cylinder body 6, exhaust valve plate 7, diaphragm seal 8, relief opening 10, air aspiration cavity 12, intakeport 13, piston cavity 14, exhaust cavity 15, valve plate 16, suction valve chip 17, hemisphere 20, piston 21, main shaft 23 is formed, and is fixed with swash plate 4 on the main shaft 23, piston 21 hangs on the swash plate 4 by hemisphere 20, below cylinder body, be equipped with one group by suction valve chip 17, valve plate 16, exhaust valve plate 7, the suction and discharge assembly that diaphragm seal 8 is formed, piston cavity 14 communicates with air aspiration cavity 12 by suction valve chip 17, and air aspiration cavity 12 communicates by the sucking pipe of intakeport 13 with the outside.Piston cavity 14 communicates with exhaust cavity 15 by exhaust valve plate 7, and exhaust cavity 15 communicates with outside outlet pipe by relief opening.Swash plate 4 rotates with main shaft 23 when main shaft 23 rotates, piston 21 in the piston cavity 14 of cylinder body 6 along with straight reciprocating motion is done in the rotation of swash plate 4.When piston 21 moves upward, piston cavity 14 spaces increase, pressure reduces, and the medium in the air aspiration cavity 12 enters into piston cavity 14 by suction valve chip 17, when piston 21 moves downward, suction valve chip 17 is closed, the space of piston cavity 14 reduces, and pressure increases, and the high-pressure medium in the piston cavity 14 is discharged in the exhaust cavity 15 by exhaust valve plate 7, discharge by relief opening 10, finish compression process one time.The circumferencial direction of main shaft 23 can be arranged a plurality of pistons, and another part piston is in exhaust when a part of piston is air-breathing, and in the process that swash plate 4 rotates a circle, all pistons are finished suction and discharge circulation.
Be coated with polytetrafluoroethylmaterial material on the circumference of piston 21, both having guaranteed has good sealability, has increased wear-resisting property again, and the friction of piston motion is reduced, and the power of consumption of engine reduces, and reaches energy-conservation effect.
