The silent volution tray is provided with air exhaust holes and a circle of conducting bumps around the air exhaust holes in the back of the silent volution tray; the middle of the back machine body is provided with a lead convex table which aims at the flow lump; the one-way valve consists of a valve head in the middle of the lead lump and a preliminary spring ; the front end of the valve has an airproof plate which can withstand the air exhaust holes; the back end of the valve end is provided with a lead hole and the preliminary spring is positioned between the back end of the valve end and the back machine body of the compressor; the lead convex table of the back machine body crosses the preliminary spring and extends into the lead hole of the valve head. The utility model can control the pressure and lead the air exhaust as the one-way valve is combined with the silent volution tray of the volution compressor.
Description
Technical field
The utility model relates to the scroll compressor in a kind of automotive air-conditioning system, relates in particular to the one-way valve of scroll compressor.
Background technique
The gas of High Temperature High Pressure drains into exhaust cavity by the exhaust port in the middle of the dish of quiet whirlpool in the car air conditioner scroll compressor, an oil return apparatus is set to reclaim the lubricated oil droplet of discharging with gas behind the dish of quiet whirlpool.Exhaust port place at quiet whirlpool dish is provided with an expulsion element, and it mainly plays the effect of unidirectional conducting gas in oil return apparatus, and the rationality of the design of expulsion element and superiority have determined the compressor volume that oil return apparatus is shared and the efficient of oil return apparatus greatly.Existing expulsion element is to adopt the exhaust valve plate design, and this structure not only has the defective of well-known fatiguability distortion, and is used in the pressure control that is unfavorable for gas in the oil return apparatus.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of one-way valve of the scroll compressor of comparatively optimizing, and it has guiding and pressure control function.
The utility model is to solve the problems of the technologies described above the one-way valve that the technological scheme that adopts provides a kind of scroll compressor, be combined on the quiet whirlpool dish of body behind the compressor, described quiet whirlpool disk center is provided with exhaust port, quiet whirlpool dish is provided with a circle baffle behind around exhaust port, baffle has the guide channel of side direction, back body center is provided with the guide ledges of aligning baffle central authorities, described one-way valve comprises a piston head and a preloading spring of being located at described baffle central authorities, the front end of piston head has the sealing surface that withstands described exhaust port, the piston head rear end is provided with a pilot hole, described preloading spring places behind piston head rear end and the compressor between the body, guide ledges on the back body is passed preloading spring, stretches in the pilot hole of piston head.
In the one-way valve of above-mentioned scroll compressor, described piston head sidewall also is provided with the window that is communicated with described pilot hole, so that pilot hole is communicated with the guide channel of baffle.The quantity of described window is 3～5.
The utility model makes it compared with prior art owing to adopt technique scheme, has pressure control and exhaust guide function, and the indefatigability distortion, and this one-way valve can be used to improve the inner space utilization ratio of compressor, the design difficulty of reduction compressor.
Description of drawings
Below in conjunction with the drawings and specific embodiments feature and advantage of the present utility model are described, wherein:
Fig. 1 is the scroll compressor part sectioned view that is provided with an embodiment's of the utility model one-way valve;
Fig. 2 is the partial enlarged drawing of compressor shown in Figure 1 at the one-way valve place;
Fig. 3 is an embodiment's of the utility model a piston head structural drawing.
Embodiment
Please illustrated in figures 1 and 2 in conjunction with consulting, be provided with quiet whirlpool dish 3 in the back body 2 of compressor 100, quiet whirlpool is coiled 3 centers and is provided with exhaust port 30, quiet whirlpool dish central authorities behind is provided with a circle baffle 31, baffle 31 has the guide channel 310 of side direction, is used to derive gas and reclaims oil droplet for oil return apparatus (figure does not show).
Characteristics of the present utility model are dexterously with the valve body of baffle 31 as one-way valve 1, its central authorities have can ccontaining one-way valve 1 valve pocket, the exhaust port 30 of quiet whirlpool dish is as the inlet of one-way valve 1, back body 2 is as the valve seat of one-way valve 1.Therefore 1 need of one-way valve comprise a piston head 11 and a preloading spring 12.Piston head 11 and preloading spring 12 are located in the cavity of a circle baffle 31 central authorities, utilize baffle 31 circumferentially to locate with axially directed, the sealing surface 111 of piston head 11 is aimed at quiet whirlpool dish exhaust port 30, preloading spring 12 withstands on behind the compressor on the body 2, back body 2 centers are provided with a guide ledges 20, this guide ledges 20 stretches in the pilot hole 112 of piston head 11, for the preloading spring 12 of one-way valve plays circumferentially location and axially reset guide.These two location are used for guaranteeing to coil moving axially of exhaust port 30 along quiet whirlpool all the time in the one-way valve 1 whole motion in working order.In addition, guide ledges 20 is also provided convenience for preloading spring 12 is installed simultaneously, and when mounted, preloading spring 12 is enclosed within on the boss 20, and back body 2 covers on quiet whirlpool dish 3 then.
Because guide ledges 20 stretches in the pilot hole 112 of piston head, when piston head 11 to-and-fro motion, need compress the gas in the pilot hole and be subjected to big resistance, therefore preferably offer 3～5 windows 113 at the piston head sidewall, as shown in Figure 3, so that the guide channel 310 of pilot hole 112 with baffle 31 connected.
In installment state shown in Figure 1, the preloading spring 12 of one-way valve 1 has had certain decrement (size of decrement is relevant with the exhaust pressure value of setting) in advance, can guarantee that like this piston head 11 can be close to quiet whirlpool dish 3 tightly, block quiet whirlpool dish exhaust port 30, make at 3 li compressed gases of quiet whirlpool dish only at the gas of discharging high pressure above backing down one-way valve 1 in certain setup pressure value through baffle 31.Equally, when the pressure of exhaust was lower than certain setup pressure value, one-way valve 1 recovered original position, makes compression chamber enter the seal compression state once more.
Because adopt above-mentioned structure, one-way valve of the present utility model can carry out pressure control, its structure is difficult for producing fatigue deformation simultaneously.
Above embodiment's explanation only is preferred embodiment explanation of the present utility model, and those skilled in the art can make the replacement and the modification of other all equivalence according to the foregoing description explanation of the present utility model.Yet these are replaced and revise according to all equivalences that the utility model embodiment is done, and belong to invention spirit of the present utility model and reach by in the claim that claim defined.
