Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figures 1 to 3, the compressor of the embodiment of the present invention comprises motor 1 and drives with motor 1 pump housing be connected.Motor 1 comprises motor stator 11 and rotor 12.The pump housing comprises roller 2, cylinder 3 and slide plate 4.Rotor 12 is fixed on outside motor stator 11.
It is outer and form the meniscate compression chamber 31 for pressurized gas with roller 2 that cylinder 3 is set in roller 2.Cylinder 3 comprises the suction port 32 for introducing gas to be compressed and the air outlet 33 for exporting pressurized gas.Slide plate 4 is arranged between suction port 32 and air outlet 33.Compression chamber 31 is divided into low-pressure cavity and hyperbaric chamber by slide plate 4.Low-pressure cavity communicates with suction port 32, and hyperbaric chamber communicates with air outlet 33.In the process that roller 2 rotates at cylinder 3, constantly change the volume of low-pressure cavity and hyperbaric chamber, thus achieve the compression treating pressurized gas.
In the present embodiment, roller 2 is set on rotor 12 regularly, and roller 2 is consistent with the bearing of trend of rotor 12.Roller 2 comprises suitable for roller 2 being set in the receiving cavity on rotor 12 with rotor 12.Roller 2 rotates with the rotation of rotor 12.Avoid motor and the pump housing in the axial direction be separated arrangement, effectively reduce the volume of roller type compressor.
As illustrated in Figures 5 and 6, the sleeve 22 that roller 2 comprises shank 21 and is fixed on rotor 12, sleeve 22, slide plate 4 and cylinder 3 form active chamber.The inner chamber of sleeve 22 is suitable cylindrical with the shape of rotor 12, and inner chamber, motor stator 11, rotor 12 and cylinder 3 are arranged coaxially.The periphery circle of sleeve 22 is arranged prejudicially with the inner circumferential circle of sleeve 22.Sleeve 22 periphery is also cylindrical, and the periphery of sleeve 22 and the inner chamber of sleeve 22 are arranged prejudicially.
In the present embodiment, sleeve 22 and shank 21 are wholely set, and sleeve 22 is fixedly connected with rotor 12.
As shown in Figure 2, the periphery of sleeve 22 abuts with the inwall of cylinder 3 with the distance farthest at the center of the inner chamber of sleeve 22.Thus make to form meniscate compression chamber between sleeve 22 and cylinder 3.When sleeve 22 rotates with rotor 12, the volume of hyperbaric chamber and low-pressure cavity constantly changes.During hyperbaric chamber volume-diminished, the volume of low-pressure cavity increases.The process of hyperbaric chamber volume-diminished is the process of pressurized gas, and the process that low-pressure cavity volume increases is the process to low-pressure cavity inflation.
