Embodiment
Embodiment 1
Refrigeration agent is shuttling movement in air-conditioning system loop, and in the loop, vaporizer exports the refrigeration agent of high-temperature low-pressure state, this refrigerant gas input compressor, compressor compresses it, is converted into high-temperature high-pressure refrigerant gas, then exports to condenser.
For being arranged in the intakeport of compressor, relief opening or the pipeline that is connected with the intakeport of compressor, relief opening.The present embodiment is for oblique tray type compressor, pulsation controlling device is located at the intakeport of compressor, introduce structure and the working principle of compressor pulsation controlling device, because this pulsation controlling device is only arranged in fluid passage, not relevant to the form of compression member, therefore can also directly apply on the compressor of other type, such as scroll compressor, realize identical effect.
It is the sectional view of the existing oblique tray type compressor for Vehicular air-conditioning apparatus shown in Fig. 1.There is a pair front-bank rotor housing 2 and rear-bank rotor housing 3, enclose and form crankshaft cavity 11.The rear end that front end housing 14 is connected to the front end of front-bank rotor housing 2, back cylinder cover 15 is connected to rear-bank rotor housing 3, front end housing 14, back cylinder cover 15 are respectively equipped with air aspiration cavity 32 and exhaust cavity 31.Plate member 20 is equipped with, for the break-make between control cylinder 30A, 30B and air aspiration cavity 32, exhaust cavity 31 between front end housing 14 and front-bank rotor housing 2, between back cylinder cover 15 and rear-bank rotor housing 3.Bolt 16 passes front end housing 14, plate member 20, front-bank rotor housing 2, rear-bank rotor housing 3, plate member 20 and back cylinder cover 15 etc. and tightens, and forms a compression case.
Live axle 1 is connected across crankshaft cavity 11, and live axle 1 is provided with swash plate 5, forward thrust bearing 6A, back pressure bearing 6B, and the outside of thrust-bearing 6A, 6B is supported by front-bank rotor housing 2 and rear-bank rotor housing 3 respectively.When live axle 1 drives swash plate 5 to rotate, the multiple pistons 17 around swash plate 5 are reciprocating.During the motion of piston 17 forward end, there is vacuum in the cylinder 30B of rear end, forces air-flow to flow to cylinder 30B direction; When piston 17 moves to the back-end, the gas in the cylinder 30B of rear end is compressed and discharged to exhaust cavity 31.The to-and-fro motion of piston 17 makes refrigeration agent form the air-flow of suction, compression, discharge compressor.
Compressor housing offers many air-flow paths, flows within the compressor for refrigerant gas, comprise intakeport 21, air intake passage 22, exhaust passage, relief opening successively.Intakeport 21 is connected with vaporizer (not shown), introduces refrigeration agent to compressor.Intakeport is communicated with air aspiration cavity 32 by air intake passage 22.Exhaust cavity 31 is communicated with relief opening by exhaust passage.Relief opening is communicated with condenser (not shown), and refrigeration agent is discharged compressor.
As shown in Figure 2, at intakeport or/and relief opening arrange pulsation controlling device 25.Pulse moves controlling device 25 in disc-shaped, and edge is the fixing part 26 for installing on the compressor, and center is active part (being positioned at fixing part 26 inner circumferential side), and active part comprises several quadrant valves 28, and the perimembranous of quadrant valve 28 is connected with fixing part 26.Groove 29 is had between the sideline of each quadrant valve 28, inter-adhesive when can prevent quadrant valve 28 from opening, and form pre-opening.The root of groove 29 is with fillet R, and when having avoided distortion, rubber ftractures.
During compressor operating, active part changes with the change quadrant valve 28 of air-flow the amplitude opened, thus increases or reduce aperture.Fixing part 26 and active part are one of the forming, and be made up of rubber, the damping constant of rubber material is higher, and elasticity coefficient is lower, therefore can prevent pulsation controlling device 25 from producing with air-flow the problem resonated.Hydrogenation nitrile rubber HNBR is selected in recommendation.
Fig. 3 A show events portion is in the shape of nature when minimum (quadrant valve 28 open amplitude), when the compressor is operated, air motion promotion rubber deforms, during stream pressure height, circulation area increases, the shape of Fig. 3 B under expansion state when maximum (quadrant valve 28 open amplitude).When stream pressure is low, circulation area reduces, and the pressure surge of valve outlet port is reduced, and reaches the object reducing pulsation.
The pulsation controlling device of the present embodiment can adopt back-up ring 34 or hexagonal socket nut 35 to be fixed on suction/relief opening.Adopt the structure of hexagonal socket nut compression as shown in Figure 4, for intakeport 21, intakeport is with step plane 36, and fixing part 26 lies against on step plane, and active part is unsettled in intakeport 21.Active part folding during work, causes fixing part 26 and involves, and is compressed by fixing part with back-up ring 34 or interior hexagonal spiral shell 35 mother, to keep the global shape of pulsation controlling device.
Pulsation controlling device 25 integrated punching of the present embodiment forms, and compared with prior art, saves the component of 75%; In the form of sheets, do not take up room, be conducive to the miniaturization of compressor; Do not need during assembling to control initial stressed state, decrease controlling unit yet.Therefore, the present embodiment has obvious advantage in production difficulty, product cost.But the deficiency also existed, because material is softer, during by back-up ring or nut compression fit, there are wrinkle to prevent it in the state preferably adopting special fixture to make pulsation controlling device to keep smooth.
Embodiment 2
As shown in Figure 5, active part (the fixing part 26 inner circumferential side) shape of pulsation controlling device 25 is comprised the some pores 37 circularizing array.During compressor operating, active part elongates with the change of air-flow or shortens, and to increase or to reduce the area of pore, thus increases or reduces aperture.Fixing part and active part are one of the forming, and are made up of rubber.Fig. 6 A and Fig. 6 B difference show events portion is in nature (when stomatal size is minimum) and the shape under expansion state (when stomatal size is maximum).
Embodiment 3
As shown in Fig. 7 A, 7B, wrap up with the edge of metal cage 39 pairs of fixing parts 26, pulsation controlling device 25 is formalized, prevent from, when assembling compresses, wrinkle occur.Shown in Fig. 7 A, Fig. 7 B is increase metal cage 39 on embodiment 1 basis, is also suitable in fact to the pulsation controlling device 25 in embodiment 2.Ringwise, and cross section roughly becomes U-shaped to metal cage 39, and fixing part 26 is entrenched in metal cage 39.
Embodiment 4
As shown in Fig. 8 A, 8B, wrap up with the edge of resin cage 40 pairs of fixing parts 26, extend radially out some flanges 41 around retainer 40, resin, with bending elasticity, offers annular groove 42 around the intakeport 21 above step surface.During installation, press pulsation controlling device 25 to intakeport 21, its flange 41 occurs bending and deformation, until it snaps in annular groove 42, flange 41 recovers nature shape, pulsation controlling device 25 is kept the position of annular groove 42.Shown in Fig. 8 A, 8B is increase resin cage 40 on embodiment 1 basis, is also suitable in fact to the pulsation controlling device 25 in embodiment 2.
