Description
Technical field
The utility model relates to a kind of vortex compressor of automobile prevents the structure of high pressure side oil accumulation.
Background technique
Conventionally vortex compressor of automobile is horizontal type structure, separate by seal ring in its high low pressure chamber, in the pump housing, friction pair adopts rolling friction more, because automobile running is unstable and friction pair characteristic, limited by vortex compressor of automobile structure and operating conditions, can not guarantee stable liquid lubricating oil supply system, generally only require a small amount of refrigerator oil, therefore lubricating system adopts the oil mist lubrication mode that compressor cold media air flow process carries oil droplet.Move and adopt radial and axial flexible design because scroll compressor orbiter adopts translation mode, therefore there is very little linear velocity and contact stress, be therefore applicable to very much oil starvation environment.
Traditional vortex compressor of automobile structure enters in high pressure gas cavity and carries out Oil-gas Separation when exhaust, and the oil after separation accumulates in the below of high pressure gas cavity, because the exhaust port of fixed scroll is at middle part, therefore below high pressure gas cavity, may accumulate part oil.Therefore need to allow this part oil enter circulation or enter low-pressure cavity oil sump.Conventionally way is between high low pressure chamber, to offer pressure reduction throttle structure, but offering this structure also can cause the leakage of high pressure to low pressure, thereby affects compressor performance.If compressor oil return is simultaneously not smooth or occur long-pending oil, will reduce low voltage side and store oil mass, oil content in cold media air is reduced, affect lubrication effect.
Compressor high pressure gas cavity is because the oil droplet wherein comprising from the gas flow rate of fixed scroll exhaust port discharge reduces occurs sedimentation phenomenon and accumulates in compressor high pressure gas cavity bottom in addition, although this part trapped fuel amount absolute value is less, comparing vehicular compressed machine volume read-out is also no small ratio.Therefore must design and make this part oil mass get back to compressor low voltage side or enter circulation.Traditional method is to make the long-pending oil of high pressure gas cavity bottom slowly or intermittently get back to compressor low voltage side by the device such as throttle capillary tube or pressure difference valve, but this project organization is realized difficulty, and in the time of long-pending shortage of oil, can produce the high low pressure problem of collaborating, thereby compressor performance is declined.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of vortex compressor of automobile and prevents the structure of high pressure side oil accumulation, this structure effectively prevents the oil accumulation phenomenon of compressor high pressure gas cavity, guarantee the lubrication effect of compressor, avoid collaborating of compressor high low pressure chamber, guaranteed the ride quality of compressor.
For solving the problems of the technologies described above, the utility model vortex compressor of automobile prevents that the structure of high pressure side oil accumulation from comprising front shell cover, rear shell cover, fixed scroll and orbiter, described front shell cover and rear shell cover are located at respectively described fixed scroll both sides, described orbiter is located in described fixed scroll and between described front shell cover and rear shell cover, the intermediate compression chamber of described fixed scroll is provided with exhaust port, in the substrate of described fixed scroll, offer perforation aperture, described perforation aperture one end is communicated with described exhaust port, the other end is communicated with the accumulating at lower part oil district of fixed scroll bottom and high pressure gas cavity.
The structure that prevents high pressure side oil accumulation due to the utility model vortex compressor of automobile has adopted technique scheme, be that this structure comprises front shell cover, rear shell cover, fixed scroll and orbiter, described front shell cover and rear shell cover are located at respectively described fixed scroll both sides, described orbiter is located in described fixed scroll and between described front shell cover and rear shell cover, the intermediate compression chamber of described fixed scroll is provided with exhaust port, in the substrate of described fixed scroll, offer perforation aperture, described perforation aperture one end is communicated with described exhaust port, the other end is communicated with the accumulating at lower part oil district of fixed scroll bottom and high pressure gas cavity.This structure effectively prevents the oil accumulation phenomenon of compressor high pressure gas cavity, guarantees the lubrication effect of compressor, avoids collaborating of compressor high low pressure chamber, has guaranteed the ride quality of compressor.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation that the utility model vortex compressor of automobile prevents high pressure side oil accumulation.
Embodiment
As shown in Figure 1, the utility model vortex compressor of automobile prevents that the structure of high pressure side oil accumulation from comprising front shell cover 1, rear shell cover 2, fixed scroll 3 and orbiter 4, described front shell cover 1 and rear shell cover 2 are located at respectively described fixed scroll 3 both sides, described orbiter 4 is located in described fixed scroll 3 and between described front shell cover 1 and rear shell cover 2, the intermediate compression chamber of described fixed scroll 3 is provided with exhaust port 31, in the substrate of described fixed scroll 3, offer and connect aperture 32, described perforation aperture 32 one end are communicated with described exhaust port 31, the other end is communicated with the accumulating at lower part oil district of fixed scroll 3 bottoms and high pressure gas cavity.
In the time of compressor actual motion, the refrigerator oil that accumulates in high pressure gas cavity 11 accumulating at lower part oil districts 12 is entered the intermediate compression chamber 13 of fixed scroll under the effect of compressor high low pressure chamber pressure reduction by perforation aperture 32, carry and enter systemic circulation by the scavenging action of exhaust port 31, although can produce certain compression loss of owing, compare high low pressure and directly collaborate much smaller on compressor performance impact; When after compressor shutdown; trapped fuel in high pressure gas cavity 11 is got back to compressor low voltage side under the high pressure of high pressure gas cavity 11 and the low pressure effect in fixed scroll intermediate compression chamber 13; thereby guarantee the trapped fuel amount of compressor low voltage side; make the enough oil droplets of compressor cold media air flow process portability realize the oil mist lubrication of compressor; improve lubrication effect, guaranteed compressor operating performance.
