(5) embodiment:
The present invention has the basic structure of common hermetically sealed compressor, it includes shell, be contained in the cylinder block 1 in the shell, cylinder head 2, motor, and bent axle 21, piston 17, linkage mechanism 22, interior exhaust coil pipe etc., particularly in the present invention, set up a resonant cavity 8 in the enclosure, this resonant cavity 8 preferably and cylinder block 1 make one, referring to Fig. 1,2,3,4, in the present embodiment resonant cavity 8 be arranged on cylinder block 1 cylinder head left side and with exhaust noise silencing chamber 6 symmetric arrangement with balance movement (resonant cavity 8 also can be arranged on other correct position of cylinder block 2 certainly).Processing for the benefit of, resonant cavity 8 is a fabricated structure, be that resonant cavity 8 is by forming with cylinder block 2 resonant cavity seats 9 cast in block and loam cake 10, and adopt screw 11 to join (resonant cavity 8 also can be to make the hollow cavity of airtight foundry goods by special casting technique certainly, and with cylinder block 2 cast solids) together.(its cross-section area is 2-60mm to draw a duct 12 from resonant cavity 8 2) be communicated with the hyperbaric chamber 7 (referring to Fig. 4) of cylinder head, promptly constitute the present invention.
Resonant cavity 8 among the present invention can also be drawn a duct 23 and is communicated with (referring to Fig. 5) with exhaust noise silencing chamber 6.
Resonant cavity 8 among the present invention can be made independently cavity, and fixedly mount on the suitable in the enclosure position, as be fixed on (referring to Fig. 6) on the cylinder block 2, or on other correct position such as cylinder head.
Working principle of the present invention is:
When motor (not shown) drive bent axle 21, crankshaft eccentric shaft drivening rod 22, it is reciprocating in cylinder 4 that connecting rod 22 promotes pistons 17.Piston 17 begins to the lower dead center operation from top dead center, and the gas pressure in the cylinder 4 descends, and when moving to certain distance, exhaust valve plate 19 is closed under the effect of the elastic force of gas pressure difference between cylinder head hyperbaric chamber 7 and the cylinder 4 and exhaust valve plate 19 automatically; Piston 17 continues operation, gas pressure in the cylinder 4 continues to descend, when reruning to certain distance, gas pressure in the cylinder 4 drops to littler than the interior gas pressure of air intake passage 15 (cylinder head low-pressure cavity), and when its difference is enough to overcome the elastic force of suction valve chip 18, suction valve chip 18 is opened, the inner face that gas just enters into cylinder 4 in the air intake passage 15 when piston 17 moves to lower dead center till.Then, when piston 17 moves to lower dead center, will begin immediately to move to top dead center from lower dead center, gas pressure and temperature in the cylinder 4 will raise, when moving to certain distance, suction valve chip 18 is closed under the effect of the elastic force of gas pressure difference between cylinder 4 and the cylinder head air intake passage 15 and suction valve chip 18 automatically; Piston continues operation, gas pressure in the cylinder 4 continues to raise, when reruning to certain distance, gas pressures in the cylinder 4 are elevated to elastic force than gas pressures and exhaust valve plate 19 in the hyperbaric chamber 7 of cylinder head big the time, exhaust valve plate 19 is opened, and the refrigerant gas of High Temperature High Pressure just enters in the hyperbaric chamber 7 of cylinder head in the cylinder 4.
Then, high-temperature high-pressure refrigerant gas in the cylinder head hyperbaric chamber 7, on the one hand, enter in the exhaust resonant cavity 8 along the duct 12 between exhaust resonant cavity 8 and the cylinder head hyperbaric chamber 7, with the mixing of pulsing mutually of the gas of its inner High Temperature High Pressure, the refrigerant gas of the High Temperature High Pressure that ejects in the cylinder 4, interact with the relative static high temperature and high pressure gas of retaining in the exhaust resonant cavity 8, so just can reduce high pressure gas air-flow wave amplitude, thereby can consume the acoustic energy of part exhaust fluid.On the other hand, the high-temperature high-pressure refrigerant gas that comes out in the cylinder head hyperbaric chamber 7, the duct 20 along between cylinder head hyperbaric chamber 7 and the exhaust noise silencing chamber 6 enters into 6 inside, exhaust noise silencing chamber, and exhaust coil pipe in being discharged to then enters the pipeline of refrigeration system.Comprehensive above 2 points, the refrigerant gas of High Temperature High Pressure in the cylinder hole, by the exhaust port on the valve plate 13 14, when entering cylinder head hyperbaric chamber 7, because exhaust noise silencing chamber 6 is branch flow relations in parallel with exhaust resonant cavity 8, the volume of its exhaust receiving cavity, it is volume by cylinder head hyperbaric chamber 7, volume with exhaust resonant cavity 8, and the volume three volume sum in exhaust noise silencing chamber 6 (and traditional flow passage structure is the exhaust noise silencing chamber that one-level exhaust noise silencing chamber or two-stage are connected mutually, the volume of its exhaust receiving cavity is by the volume of cylinder head hyperbaric chamber 7 and exhaust noise silencing chamber 6 both volume sums), obviously adopt the flow passage system of structure of the present invention, the volume of the flow passage structure that the volume of its exhaust receiving cavity is more traditional is big, under the same situation of interior exhaust coil pipe internal diameter cross sectional area and length, the refrigerant gas of High Temperature High Pressure like this, come out from the exhaust receiving cavity, it is many that the time that the exhaust coil pipe is consumed in entering will be grown, so the 6 gas pulses wave frequencies of discharging will be littler from the exhaust noise silencing chamber, thereby also can reduce exhaust noise.
