Description
The application number that is entitled as " valve assembly of hermetic type compressor " that the application submits to Patent Office of the People's Republic of China July 20 calendar year 2001 for Lejin Electronic and Electric Appliance Co Ltd (Tianjin) is dividing an application of 01132572.0 Chinese patent application.
Technical field
The present invention relates to a kind of hermetic type compressor, particularly relate to a kind of hermetic type compressor valve assembly, this assemblying body has been simplified suction valve and the expulsion valve structure that refrigerant gas is come in and gone out and regulated from cylinder, can make dead volume (dead volume) reach minimum simultaneously.
Background technique
Generally speaking, compressor is to compress the machine of discharge with sucking working fluid, carries out the function that the refrigerant gas through vaporizer is compressed to High Temperature High Pressure in the such refrigerating air-conditioning of refrigerated warehouse or air conditioner.The mechanism portion and the compression mechanical part one that produce this driven compressor power are called hermetic type compressor.
In addition, above-mentioned hermetic type compressor also is divided into rotary compressor, reciprocating movement type compressor and scroll compressor according to the form of compression mechanical part.Be elaborated with reference to the structure of accompanying drawing at this to hermetic type compressor.
Fig. 1 is the sectional view of the general closed reciprocating compressor structure of expression.
As shown in Figure 1, above-mentioned closed reciprocating compressor is equipped with the mechanism portion that produces rotating force in the seal container that forms the confined space of determining by supplying electric current, and the compression mechanical part that is come compression refrigerant gas by the rotating force of above-mentioned mechanism portion.
Above-mentioned mechanism portion is made of stator (Stator3) on the bottom surface that is supported on seal container 1 with spring and the rotor (Rotor4) that is inserted in the said stator.
Above-mentioned compressor structure portion is positioned at the top of stator 3, by the cylinder of compression one side refrigerant gas, have insertion groove cylinder body, be pressed into bent axle 7 that top in the rotor has eccentric part 7a, with the eccentric part that is connected above-mentioned piston and bent axle the connecting rod that rotatablely moving of bent axle converts above-mentioned piston linear reciprocating motion to constituted by above-mentioned insertion groove at the piston of above-mentioned cylinder interior linear reciprocating motion.
In addition, above-mentioned compressor structure portion comprises combining with an end of cylinder and regulates the valve assembly V that refrigerant gas is come in and gone out, and is used for open above-mentioned valve assembly and has from the valve mechanism cover of the cavity of valve assembly discharging refrigerant gas flow path.
Dispose the suction noise device 11 that is connected with cylinder interior on a side of above-mentioned valve mechanism cover, above-mentioned suction noise device is drawn in the above-mentioned cylinder refrigerant gas and leads when reducing noise.
The suction pipe 12 that flows into refrigerant gas is combined in a side of above-mentioned seal container 1, inhales noise device inlet side so that its end is positioned at, and the opposite side of above-mentioned seal container is combined with the discharge tube (not shown in the figures) of discharging refrigerant gas.
The refrigerator oil that has been covered with the established amount that prevents each mechanism components wearing and tearing usefulness on the bottom surface of above-mentioned seal container.
If make the closed reciprocating compressor energising of this structure, then by the interaction of said stator and rotor, rotor will rotate, just rotate by the turning crankshaft of above-mentioned rotor.When 7 rotations of above-mentioned bent axle, be combined in connecting rod 9 on the eccentric part and will rotatablely move and convert linear reciprocating motion to, piston is moved in cylinder interior.
At this moment the refrigerant gas that flows into by suction pipe utilizes the motion of above-mentioned piston and the action of valve assembly to be drawn into cylinder interior after inhaling the noise device, is compressed into High Temperature High Pressure afterwards and discharges by discharge tube.
Fig. 2 is the exploded perspective view of the valve assembly structure of expression prior art.
As shown in Figure 2, the valve assembly of prior art is by constituting at the cylinder head 20 that disposes between end of cylinder and the valve mechanism cover, the suction valve 30 of band configuration between end of above-mentioned cylinder and cylinder head, the discharger that disposes between above-mentioned cylinder head and valve mechanism cover.
Above-mentioned cylinder head 20 is made of the body with certain thickness and area, and a side of above-mentioned body forms suction port 22 and exhaust port 23 respectively.
Above-mentioned suction valve 30 is by having the grooving 32 that forms with the corresponding position of above-mentioned cylinder head suction port on corresponding to the thin plate 31 of this bulk area of cylinder head, constituting by the exhaust port 34 that opens and closes switching portion 33 that above-mentioned grooving opens and closes suction port, form on the position of side corresponding to cylinder head exhaust port 23 of above-mentioned switching portion.
Though not shown, above-mentioned discharger by the expulsion valve that opens and closes the cylinder head exhaust port, strengthen valve spring that above-mentioned expulsion valve rigidity uses, limit the holding member that above-mentioned expulsion valve and valve spring move and constitute.
The valve assembly of this structure is to place the state of cylinder end to link together with many clamping bolts 13 down successively suction valve, cylinder head, discharger and valve mechanism cover.
Start to above-mentioned valve assembly describes below.
At first, in a single day above-mentioned piston moves to lower dead centre from the upper dead center of cylinder, is then made the switching portion bending of suction valve by the inhalation power of above-mentioned cylinder interior, thereby opens the suction port of cylinder head.At this moment, through suction pipe and suction noise device refrigerant gas is drawn in the cylinder successively.
Then, when lower dead centre moved to upper dead center, the switching portion of above-mentioned suction valve simultaneously returned to original state at above-mentioned piston, and one side is sealed the suction port of cylinder head.Simultaneously, the refrigerant gas of above-mentioned cylinder interior is compressed in rapid succession, up to the pressure state of setting, by compressive force expulsion valve is opened then.At this moment, the refrigerant gas that has compressed in the cylinder passes through the exhaust port of suction valve and the exhaust port of cylinder head in turn, and the cavity by valve mechanism cover is discharged to the outside.
Yet the combinations thereof body has following shortcoming:
The first, although above-mentioned suction valve 30 can as far as possible fully open and close the suction port of cylinder head, constitute by thin plate with the corresponding size of cylinder head body dimension.This just means that suction valve compares with its function and have relatively large size, and this also is the reason that manufacturing expense rises.
In addition, because above-mentioned reason, above-mentioned thin plate 31 should form grooving 32 on corresponding to the position of cylinder head suction port 22, and also forms other exhaust port on the position of above-mentioned cylinder head exhaust port correspondence.Thus, make the structure of above-mentioned suction valve 30 become complicated, increased manufacturing process's number and assembling procedure number, thereby reduced productivity.
In addition, the problems referred to above also are the same under suction valve place but also the situation at discharger not only.
The second, the grooving of switching portion 33 usefulness of above-mentioned formation suction valve 32 has produced dead volume in cylinder interior.This dead volume is the main cause that the refrigerant gas compression efficiency reduces.
