Embodiment
A kind of air compressor as shown in Figure 1, have cylinder head 1 and cylinder sleeve 2, be provided with low-pressure cavity 3 and hyperbaric chamber 4 in the cylinder head 1, be provided with intakeport 5 between low-pressure cavity 3 and the cylinder sleeve 2, be provided with relief opening 6 between hyperbaric chamber 4 and the cylinder sleeve 2, be provided with suction valve chip 7 and exhaust valve plate 8 respectively at intakeport 5 and relief opening 6 places; Be provided with piston 9 in cylinder liner 2, piston 9 connects driving mechanism 17; The cylinder head 1 of low-pressure cavity 3 is provided with suction port 10, and the cylinder head 1 of hyperbaric chamber 4 is provided with air outlet 11; Air outlet 11 connects gas holder 12, is provided with one-way valve 13 between air outlet 11 and gas holder 12.In order to realize unloading to the cylinder interior pressurized gas, has one at cylinder head 1 top to the recessed cavity 14 of hyperbaric chamber 4, the bottom surface of cavity 14 is clinoplain and adjacent row air valve plate 8, on the bottom surface of cavity 14, offer the first unloading hole 15, at cylinder sleeve 2 during with hyperbaric chamber 4 conductings, exhaust valve plate 8 open modes, exhaust valve plate 8 is fitted with the bottom surface of cavity 14 and is sealed the first unloading hole 15, and its aperture is 0.1～0.3mm.In addition, offer the second unloading hole 16 on the casing wall of cylinder liner 2 bottoms, its aperture is 0.5～3mm.
Air compressor working procedure described in the utility model and principle are:
Described air compressor, cavity 14 is set on the hyperbaric chamber 4 of cylinder head 2 dexterously and on the bottom surface of this cavity 14, offers the first unloading hole 15, and be implemented in the unloading of cylinder liner 2 and cylinder head 1 offering the second unloading hole 16 on the casing wall of cylinder liner 2 bottoms to the pressurized gas between the one-way valve 13.Entire work process is: driving mechanism 17 drives piston 9 and moves to cylinder liner 2 bottoms, be breathing process this moment, suction valve chip 7 is opened, exhaust valve plate 8 is closed, ambient air sucks arrival low-pressure cavity 3 by the suction port 10 of cylinder head 1, enter in the cylinder sleeve 2 by intakeport 5 by low-pressure cavity 3 again, when piston 9 moves the rear in the second unloading hole 16 backward, this moment second, unloading hole 16 participated in air-breathing, can regard another inlet hole (air inflow is less) of cylinder as, quicken ambient atmos and entered cylinder.After this enter gas holder 12 gas replenishment processes, piston 9 moves forward, gas is compressed, this moment, suction valve chip 7 was closed, exhaust valve plate 8 is opened, 8 dozens of exhaust valve plates are to the bottom surface of cavity 14 side, the bottom surface of under the effect of pressurized gas, being close to contiguous cavity 14, block unloading hole 15, first on cavity 14 bottom surfaces, pressurized gas is under the promotion of piston 9, enter hyperbaric chamber 4 by cylinder sleeve 2 by relief opening 6, and the air outlet from the hyperbaric chamber 4 11 derives, enter gas holder 12 through one-way valve 13.When air compressor boosted to specified pressure maximum with the gas in the gas holder 12, pressure controller disconnected motor power, the motor stall.
After the motor stall, at cylinder sleeve 2, hyperbaric chamber 4, gas port 11 can retain pressurized gas to the pipeline between the one-way valve 13, piston 9 at first moves towards the rear of cylinder sleeve 2 bottoms under the effect of pressurized gas, because it is big that cylinder sleeve 2 gas spaces become, cylinder sleeve 2 internal gas pressure diminish, this moment hyperbaric chamber 4, air outlet 11 to the pipeline between the one-way valve 13 gas pressure intensity greater than gas pressure intensities in the cylinder sleeve 2,8 dozens of exhaust valve plates are to relief opening 6 sides, hyperbaric chamber 4, air outlet 11 to the pipeline inner high voltage gas between the one-way valve 13 is discharged to the external world by the first unloading hole 15, when hyperbaric chamber 4, when gas pressure intensity is less than cylinder sleeve 2 internal gas pressure in the pipeline of air outlet 11 between one-way valve 13, exhaust valve plate 8 is opened, gas make-up in the cylinder sleeve 2 enters hyperbaric chamber 4, air outlet 11 is to the pipeline between the one-way valve 13, by the first unloading hole 15 pressurized gas are discharged to the external world again, reciprocation cycle is constantly discharged pressurized gas by the first unloading hole 15 to the external world.Piston 9 rearward moves under the pressurized gas active force, when arriving the rear in the second unloading hole 16, this moment second, unloading hole 16 also participated in the exhaust to the external world simultaneously, quicken the exhaust process, shorten period of exhaust, equal ambient atmosphere pressure until the cylinder interior gas pressure intensity, stop exhaust, No Load Start when so just having realized next startup air compressor.It may be noted that the utility model adopts separately the auxilliary first unloading hole 15 or the second unloading hole 16 also can reach the effect that retains pressurized gas in the same discharge cylinder, just adopting two simultaneously, to unload the hole exhaust efficiencies higher.
Common air compressor is not owing to have the first unloading hole and the second unloading hole, under the pressurized gas effect that in cylinder, retains, piston 9 in the cylinder sleeve 2 can be pushed to the bottommost of cylinder sleeve 2, this moment, connecting rod arrived horizontal position, with the angle of the moving direction of piston 9 be 0, connecting rod promotes the torque minimum of piston 9 actings, when motor starts once more, owing to leave pressurized gas, so the resistance acting that electronic drivening rod, connecting rod drive piston 9 need motor to provide powerful power to overcome pressurized gas at the cylinder internal memory.
