Preferred embodiment is described
Following description of preferred embodiments only is exemplary in itself, rather than the present invention, application of the present invention or purposes are limited.
With reference to Fig. 1, hermetic reciprocating compressor 10 is in accordance with the principles of the present invention described.Reciprocal compressor 10 comprises a can 12, and sealing shell 12 comprises a lower casing 14 and a upper casing 16 that is tightly connected mutually.Suction port passage 17 is set in the can 12.Such just as known in the art, motor 18 is set at shell 12 the insides, and this motor comprises a rotor (not being expressed out), a stator 20 and a crankshaft 22 that is connected with described rotor.Described crankshaft 22 comprises an eccentric part 24.
One piston 38 is set at the inside of cylinder 30, and is connected with a connecting rod 40, and this connecting rod 40 is connected with the eccentric part 24 of crankshaft 22.One suction passage 42 is set in the monolithic element 26 and with a cylinder 30 and a hollow section 44 and is connected, and this hollow section 44 is limited by the bell part 32 of main body 28 and forms.Preferably as shown in Figures 2 and 3, the shape of piston 38 is substantially cylindrical shape, and described piston 38 comprises a groove 46, this groove 46 is connected with an inlet channel 48, this inlet channel 48 allows to suck gas by described suction passage 42, by described groove 46, and by inlet channel 48, thereby pass in the cylinder 30 that passage 47 enters piston 38 tops, expiratory phase in compressor operation, described passage 47 is covered (this inlet leaf valve is fixed to the top of piston) by an inlet leaf valve 49.
One bleed valve assembly 50 is set in the opening end of cylinder 30.This bleed valve assembly 50 comprises a valve block 52, a discharge valve element 54 and a valve guard ring 56.Valve block 52 is disc substantially and comprises a pair of floss hole 58 that is set in the described valve block.Valve block 52 also comprises in order to hold a plurality of holes 60 of fastening piece, thereby is convenient to escape cock 54 and guard ring 56 are installed on the valve block 52.As shown in Figure 2, escape cock 54 is a reed type valves, and this valve is made by a kind of elastic material.Escape cock 54 is configured to abut against valve guard ring 56, this valve guard ring 56 is provided with an arcuate surface 62 and is also comprised the installation hole 64 (Fig. 1 has only represented one of them hole) that is used for holding fastening piece, the described fastening piece that holds extends through the installation hole 60 that is arranged in the valve block 52, and passes these holes 66 that are arranged in the escape cock 54.Escape cock 54 is provided with the otch 68 of arc, the floss hole 58 that this otch 68 is configured to from be arranged on valve block 52 is radially inside, thereby help to control the pliability of escape cock 54, so that the expiratory phase in compressor operation covers floss hole 58, floss hole 58 is left in the compression stage bending in compressor operation.The arcuate surface 62 of valve guard ring 56 has a profile, and this profile is configured to limit opening of leaf valve 54, so that pressure and operation are optimized.
By being manufactured, valve block 52 and guard ring 56 have a diameter, this diameter suitably is processed into interference fit between the inside diameter of the outer dia that allows valve block 52 and guard ring 56 and cylinder 30, thereby bleed valve assembly 50 can be assembled in the cylinder cap part 34 of monolithic element 26.The interference fit at diameter place provides the sealing and the maintenance of valve block 52 and guard ring 56.Between erecting stage, piston 38 is maintained on the precalculated position, for example, upper dead center position, and bleed valve assembly 50 is cooled to an enough low temperature and makes the diameter thermal shrinkage of assembly 50, so that described assembly 50 freely enters cylinder 30.Bleed valve assembly 50 is positioned on the piston 38 up to this assembly 50 in cylinder 30 heating and form press fit.Described press fit keeps assembly 50 and provide sealing between cylinder 30 and bleed valve assembly 50 diameter.As shown in Figure 3, between the erecting stage of bleed valve assembly 50, a kind of localization method of the piston 38 in the cylinder 30 is loads (by applying of power F) of putting upside down the bearing between connecting rod 40 and crankshaft 22, rely on the bearing play piston 38 be placed in normal upper dead center position above.The active force of gas (when compressor in when running) promote piston 38 downwards, thereby put upside down the load on the bearing and form a cold piston-valve block gap, this cold piston-valve block gap approximates the summation of the bearing play in the running gear assembly greatly.
In addition, should be noted that the interference fit between erecting stage can obtain by heating cylinder, so that before in bleed valve assembly is inserted into cylinder, make the cylinder internal expanded in diameter, rather than place room temperature environment to obtain interference fit by the cooling valve assembly and cylinder.In addition, both combinations of (heating cylinder and cooling bleed valve assembly) also are possible.And sealing between valve block 52 and cylinder 30 and maintenance also can be reinforced by using sealing compound, for example, use the LOCTITE sealing compound.
One optional embodiment is, valve block is installed in the countersink, and the diameter of this countersink is different from the diameter of cylinder.Yet this selection requires to provide Aided Machine operation, so that generate described countersink.
Preferably as shown in Figure 2, the top of piston 38 is provided with profile post 70, and when piston 38 during near upper dead center, this profile post 70 is designed to partly fill the floss hole 58 in the valve block 52.Profile post 70 further dwindles in the piston 38 of upper dead center and the gap summation between the valve block 52, thereby further increases the efficient of compressor.
Shown in Fig. 4 A and Fig. 4 B, for two kinds of dissimilar application, the size of can 12 and structure are configured to support motor 18 and monolithic element 26.In the compressor of extremely sealing, oily temperature control is important.If this oil is too warm, the greasy property reduction so just might take place and oily fault takes place.If this oil is too cold, the dilution of refrigeration agent just might influence this oily greasy property significantly so, and otherwise the reliability of compressor is produced the long-pending influence that disappears.Fuel tank temperature altitude ground depends on how compressor is used.Have in the utilization of excessive heat and high pressure ratio at these, resist the minimum heat that passes to oil and help to make oil to remain on a safety temperature district.This point can be realized by the outside that the cylinder cap of compressor is remained on oil.Utilization with ultralow heat and low pressure ratio has benefited from the heat of oil is resisted.Described heat to oil resists and can improve by flooding cylinder cap and operate gear in oil.
