Describe the compression mechanism 10 of the compressor according to this utility model first aspect embodiment below with reference to Fig. 1-Fig. 4, the compression mechanism 10 of described compressor has the advantage that noise is little.Wherein, compressor can be rotary compressor.
As Figure 1-Figure 4, the compression mechanism 10 according to the compressor of this utility model embodiment, including cylinder 100, bearing 200, exhaust valve plate 300 and lift stopper 400.
Alternatively, compressor can be vertical compressor.In the application as explained below, illustrate for compressor for vertical compressor.Certainly, those skilled in the art are appreciated that compressor can also be horizontal compressor (not shown go out).Here, it is necessary to explanation, " vertical compressor " can be understood as the central axis upright of the cylinder 100 of compression mechanism 10 in the compressor of the installed surface of compressor, for instance, as it is shown in figure 1, the central axis of cylinder 100 vertically extends.Correspondingly, " horizontal compressor " can be understood as the centerline axis parallel of cylinder 100 in the compressor of the installed surface of compressor.
Being provided with cylinder-bore 110 in cylinder 100, bearing 200 is located on the end face of cylinder 100, and bearing 200 is provided with the air vent 210 connected with cylinder-bore 110, and exhaust valve plate 300 is located on bearing 200 and can open or close air vent 210.When cylinder 100 works, exhaust valve plate 300 closes air vent 210, and gas is compressed in cylinder 100；During cylinder 100 aerofluxus, air vent 210 is discharged and arrived to gas by cylinder-bore 110, and exhaust valve plate 300 opens air vent 210, and gas approximately horizontally flows through the gap between exhaust valve plate 300 and air vent 210, and gas flows up and discharges afterwards.Wherein, lift stopper 400 is located on bearing 200 and covers exhaust valve plate 300, so, opens in the process of air vent 210 at exhaust valve plate 300, lift stopper 400 can limit the lift of exhaust valve plate 300, it is to avoid exhaust valve plate 300 is excessive and damage due to lift.
It is that cylinder 100 can be one or more, and bearing 200 can be two, and at least one in two bearings 200 is provided with air vent 210 with it will be appreciated by those skilled in the art that.Such as, when cylinder 100 is one, two bearings 200 are respectively provided in the both ends of the surface up and down of cylinder 100, and in two bearings 200 is provided with on air vent 210 or two bearings 200 and is respectively equipped with air vent 210；When cylinder 100 is multiple, multiple cylinders 100 are arranged above and below, two bearings 200 are respectively provided on the end face of upper and lower two cylinders 100, wherein, it is provided with cylinder-bore 110 in cylinder 100 above, bearing 200 above is provided with air vent 210, or, it is provided with cylinder-bore 110 in the cylinder 100 being positioned below, the bearing 200 being positioned below is provided with air vent 210, it is, of course, also possible to be respectively equipped with cylinder-bore 110 in upper and lower two cylinders 100, correspondingly, two bearings 200 are respectively equipped with air vent 210.
