Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Fig. 4 is control valve unit the 1st embodiment's exploded perspective view of the present invention.
Control valve unit of the present invention comprises by valve plate 100, expulsion valve 110, valve leaf 130 and fixedly the limiting board 150 of expulsion valve 110 and valve leaf 130 constitute.Be installed in the inboard groove part 100a that forms of valve plate 100 1 side direction on the side of cylinder.Groove part 100a is formed on the front of valve plate 100, and promptly the opposing face of being close at valve plate and cylinder forms.The exhaust port 100b that connects valve plate 100 formation is arranged in the inside of groove part 100a.Exhaust port 100b is the state of following the internal communication of cylinder with the size of appointment.The refrigerant of cylinder interior is discharged by exhaust port 100b.Exhaust port 100b is the state that protrudes from the bottom surface of groove part 100a, is protruding formation seat surface 100c on the end edge.The compare bottom surface height of groove part 100a of seat surface 100c.Side at groove part 100a forms the mobile groove 100d that prevents.Move the expulsion valve that will illustrate below preventing to insert in the groove 100d and the mobile projection that prevents of valve leaf.Inside at valve plate 100 forms suction port 100e.
The mobile bottom surface of groove 100d that prevents at groove part 100a forms in order to make expulsion valve and valve leaf certain bump (not shown) of secure more.Bump is the level of state in order to make the superincumbent expulsion valve 110 of installation, and will be corresponding to the same height of seat surface 100c of exhaust port 100b.If the height of bump and seat surface 100c is different, the 110a of switching portion of mounted thereto expulsion valve 110 can not complete closed exhaust port 100b, certain clearance occurs between 110a of switching portion and the exhaust port 100b, the pressurized air of discharging by above-mentioned gap is to the inner adverse current of pressing chamber.Therefore, the seat surface 100c of bump and exhaust port 100b is all best highly mutually.
The metal material plate that expulsion valve 110 and valve leaf 130 usefulness have certain elastic force forms.
The reason that expulsion valve 110 possesses elastic force is: in order to control the opening degree of expulsion valve 110.If expulsion valve 110 is too opened, though compression refrigerant can be discharged more glibly, expulsion valve 110 is returned to the time lengthening above the exhaust port 110b.If the recovery of expulsion valve 110 is delayed like this, the compression refrigerant of discharge is from exhaust port 110b adverse current in the pressing chamber of cylinder, and the power of compressor descends.Expulsion valve 110 has elastic force, for discharge glibly and the reinstatement rapidly that makes compression refrigerant.
The elastic force of valve leaf 130 recovers expulsion valve 110 more rapidly.If expulsion valve 110 is opened, a side of expulsion valve 110, more particularly, the 110a of switching portion be close to valve leaf 130 below.If expulsion valve 110 continues to open, valve leaf 130 is discharged from valve 110 promotions and becomes crooked upward state, and supports expulsion valve 110.Wan Qu valve leaf 130 utilizes the spring return of self to promote to be close to expulsion valve 110 below it downwards after refrigerant discharge to finish in original state like this.Thus, the recovery of expulsion valve 110 is more rapid.
By limiting board 150 expulsion valve 110 and valve leaf 130 are fixed on the valve plate 100.Limiting board 150 is pressed into groove part 100a inside and fixes, and forms the fastening foot 150a that is close to above-mentioned groove part 100a wall in the one side.Below limiting board 150, form fixedly expulsion valve 110 and valve leaf 130 fixed end push protruding 150b, and on position, form corresponding to expulsion valve 110 and valve leaf 130 fixing parts.Therefore, in the time of fixed limit plate in the groove part 100a 150, push the fixing part that protruding 150b pushes expulsion valve 110 and valve leaf 130, the fixing part of expulsion valve 110 and valve leaf 130 is interfixed.
Utilize the process of aforesaid constituting component assembled valve device as follows.
Behind smooth placement valve plate 100, make groove part 100a towards the top, insert expulsion valve 110 then in the groove part 100a.At this moment, the 110a of switching portion of expulsion valve 110 is installed in the seat surface 100c of exhaust port 100b.The top placement valve leaf 130 of the expulsion valve 110 of Cha Ruing like this.After placing valve leaf 130, make the free end 130b of valve leaf 130 specified angle that tilts upward.Then, in the last direction groove part 100a of valve leaf 130, insert limiting board 150, the fastening foot 150a of limiting board 150 is close to the wall of groove part 100a, and the fixed end of pushing protruding 150b push valve reed 130 that protrudes downwards, fixedly expulsion valve 110 and valve leaf 130.
Like this in the control valve unit of Gou Chenging, refrigerant flow into cylinder interior and compress and the process of discharging as shown in Figure 4 and Figure 5.
After the refrigerant of compressor inside is opened suction valve 170, flow into 11 li of the pressing chambers of cylinder 9 from suction port 100e.Because the piston 10 of cylinder 9 inside retreats, the pressing chamber pressure inside descends, and refrigerant flows into cylinder 9 pressing chambers 11 inside thus.If piston 10 advances, suction valve 170 cuts out, and the beginning compression refrigerant.
If piston moves on, refrigerant is compressed gradually and becomes the high pressure compressed refrigerant.Such compression refrigerant is promoted by piston, to valve plate 100 side shiftings.Then, compression refrigerant flows in the exhaust port 100b.The compression refrigerant that flows in the exhaust port 100b promotes to cover the expulsion valve 110 of exhaust port 100b and discharges from pressing chamber.Compression refrigerant through exhaust port 100b is discharged upward from the through hole 200 of valve leaf 130.Then, refrigerant flows into cooling system from end cap (not shown) and exhaust silencer (not shown) successively.
In discharge process, open if expulsion valve 110 is compressed refrigerant, be close to above the expulsion valve 110 valve leaf 130 below, valve leaf 130 is discharged from valve 110 and promotes crooked upward.Afterwards, refrigerant discharge to finish, and crooked valve leaf 130 moves downwards under the effect of elastic force, and the expulsion valve of being close to below it 110 is more promptly moved downwards.If expulsion valve 110 moves rapidly downwards as mentioned above, the 110a of switching portion of expulsion valve 110 be close to exhaust port 110b seat surface 100c above, so can prevent the compression refrigerant that discharges pressing chamber adverse current to cylinder.
As mentioned above, if through hole 200 is arranged on valve leaf 130, more promptly discharge by the valve leaf of expulsion valve top from the compression refrigerant that the pressing chamber of cylinder is discharged.
Fig. 6 illustrates the valve leaf 130 that constitutes control valve unit the 2nd embodiment of the present invention.As shown in the figure, form a plurality of through holes 210 at the free end 130b of valve leaf 130.Therefore, can make compression refrigerant pass through a plurality of through holes 210 discharges.
Fig. 7 illustrates the valve leaf 130 that constitutes control valve unit the 3rd embodiment of the present invention.As shown in the figure, form the cutting part 230 of appointment at the free end 130b of valve leaf 130.The both sides of cutting part 230 each comfortable free end 130b form, and also can only be formed on a certain position of upside or downside.In addition, when 230 of the cutting parts sides at valve leaf 130 form, the size that cutting part 230 possesses more expansion is best.
As mentioned above, the reason that forms cutting part 230 at the free end 130b of valve leaf 130 is: in order to prevent below the compression refrigerant bump free end 130b that expulsion valve 110 is discharged, and discharge more glibly.
Fig. 8 illustrates the 4th embodiment's exploded perspective view of control valve unit of the present invention.
Control valve unit forms a certain size through hole 200 as shown in the figure in the inside of valve leaf 130 free end 130b.Also form through hole 300 with through hole 200 correspondences of valve leaf 130 in the inside of limiting board 150.Therefore, insert fixed limit plate 150 in the groove part 100a, the through hole 300 of limiting board 150 is positioned at the top of the through hole 200 of valve leaf 130.
Be formed with separately under the state of through hole 200,300 at valve leaf 130 and limiting board 150 inside, the process that compression refrigerant is discharged is shown in Figure 9.Because piston-advance, and the refrigerant that is compressed to high pressure conditions flows into the exhaust port 100b of valve plate 100, and the compression refrigerant of inflow is opened and is covered with the expulsion valve 110 of exhaust port 100b and discharges.Discharge upward through the through hole 200 of valve leaf 130 and the through hole 300 of limiting board 150 from the compression refrigerant that exhaust port 100b discharges.
Owing to be formed with through hole 200,300 separately at valve leaf 130 and limiting board 150, discharge more glibly through the valve leaf and the limiting board of expulsion valve top from the compression refrigerant that the pressing chamber of cylinder is discharged.
Figure 10 a and 10b illustrate valve leaf 130 and the limiting board 150 that constitutes control valve unit the 5th embodiment of the present invention.As shown in the figure, form a plurality of through holes 210, through hole 310 with through hole 210 correspondences of valve leaf 130 is also arranged in a side of limiting board 150 in the inside of valve leaf 130 free end 130b.
Figure 11 a and 11b illustrate valve leaf 130 and the limiting board 150 that constitutes control valve unit the 6th embodiment of the present invention.As shown in the figure, form the cutting part 230 of appointment, also form cutting part 230 corresponding cutting portions 330 with valve leaf 130 in a side of limiting board 150 at the free end 130b of valve leaf 130.Cutting part 230,330 is formed on the both sides of valve leaf 130 and limiting board 150 separately, and cutting part 230,330 also can only form in a certain side.When 230,330 a certain sides at valve leaf 130 and limiting board 150 of cutting part formed, the size that forms more expansion was best.
