Detailed description of the invention
Elaborating embodiments of the invention below, the present embodiment is carried out under premised on technical solution of the present invention
Implement, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following enforcement
Example.
Embodiment 1
As shown in Fig. 1～2, the present embodiment includes: circular valve gap 1, circular lip sealing member 2, cylindrical valve spool 3 and square valve
Body 8, wherein: valve body 8 is sheathed on spool 3 bottom, four sides of valve body 8 have four through holes, and spool 3 bottom symmetry sets
Having two crescent flutings, crescent fluting forms the crescent commutation cavity for being connected adjacent through-holes, lip with valve body 8 inwall
Mouth sealing member 2 and valve gap 1 are sheathed on spool 3 successively and realize sealing.Spool 3 top is connected with motor to drive spool 3 to rotate.
As it is shown on figure 3, described crescent fluting includes the first crescent fluting 4 and the second crescent fluting 5.Two months
Sidewall profiles that is first commutation curve 6 and second commutation curve 7 of thread form fluting are all circular curve, conic section or gradually open
Line, takes the circular curve that radius is 38.5 in this example.Height H and the through-hole diameter of crescent fluting are equal.Crescent fluting
Upper and lower surface is inclined-plane.On spool 3 outer peripheral face, the circumferential lengths between crescent is slotted requires straight less than through hole
Footpath, here on spool 3 outer peripheral face circumferential lengths between crescent is slotted less than 1/2nd through-hole diameters.First crescent moon
Between the sidewall of shape fluting 4 and the second crescent fluting 5, minimum range is 3mm.
As shown in Figure 4, four described through holes are respectively as internal exchanger passage 9, compressor inlet channel 10, compression
Machine exhaust passage 11 and external heat exchanger passage 12, the diameter of four through holes is all 13.5mm.The circular cavity on valve body 8 top is
Valve body epicoele 13, the circular cavity of valve body 8 bottom is valve body cavity of resorption 14.First crescent fluting 4 and second month of spool 3 bottom
Thread form fluting 5 is all located at valve body cavity of resorption 14, and crescent fluting forms crescent commutation cavity with the sidewall of valve body cavity of resorption 14.Crescent moon
The through hole that the two ends of shape fluting are corresponding is axially in parallel.
Described lip seal part 2 is sheathed at spool 3 axle journal, is positioned at valve body epicoele 13, and with valve body epicoele 13 interference
