Embodiment
Fig. 1-Fig. 3 represents first embodiment.In the figure, different for clear and definite this embodiment's scroll compressor and in the past scroll compressor for the parts of or functional equivalent identical with Fig. 7, mark identical symbol.The lubricant oil that retains in the bottom of seal container after the throttle orifice 12 during being installed in rotary vortex rotary part 4 reduces pressure, supplies to back pressure chamber 8 by being formed on the path 13A of axle 13 inside.In addition, depressed part 14 is set, the contact path 15 at the back side of contact depressed part 14 and runner plate 4b is set at the front end of the 4a of scroll portion of rotary vortex rotary part 4.In addition, in the present embodiment, because suction pipe 1 and suction chamber 3 are overlapping with back pressure regulating mechanism 9, so be to illustrate about the center is divided into axle 13 easily.
According to this formation, because enclosed pressing chamber 5 from the lubricant oil that depressed part 14 is supplied with, move towards the center, so thermal strain and pressure distortion owing to excess load the time, and make the central part of the 4a of scroll portion of the rotation vortex 4 of the strong contact of tooth face, lubricated tooth face can prevent to produce adhesion and inordinate wear.In addition, also wave effect, can reduce from the leakage of the tooth face of scroll portion as the sealing machine fry dried food ingredients from the lubricant oil that depressed part 14 is supplied with.
In addition, because to the pressing chamber 51 of the inboard of depressed part 14 openings supplying lubricating oil more, make the effect that reduces from the leakage of the sidewall of the scroll portion of the pressing chamber of the inboard of depressed part 14 openings so can improve.
In addition, be formed at the outer circumferential side of rotary vortex rotary part 4 at depressed part 14, under the situation of pressing chamber 5 openings (not shown go out), because lubricant oil is supplied with to the pressing chamber 52 in the outside of depressed part 14 openings more, make the effect that reduces from the leakage of the sidewall of the scroll portion of the pressing chamber in the outside of depressed part 14 openings so can improve.
In addition, in the pressing chamber 5 of the opening surface that is in depressed part 14, constitute with respect between two point of contact of the 2a of scroll portion of the 4a of scroll portion of the rotary vortex rotary part 4 that forms pressing chamber 5 and fixed scroll member 2, along the length of the scroll of rotary vortex rotary part 4, the length 14a to the opening surface of pressing chamber 5 that makes at depressed part 14 is short.In this case, because the pressing chamber of depressed part 14 openings 5 is not communicated with the pressing chamber or the discharge space 5a that form than these pressing chamber 5 more close discharge sides, and, the pressing chamber 5 of depressed part 14 openings is not communicated with pressing chamber that is formed on the suction side or suction space 5b, so can simultaneously make the leakage between the pressing chamber is inferior limit, one towards pressing chamber 5 supplying lubricating oils.
Fig. 4 and Fig. 5 represent second embodiment.In using as the scroll compressor under the situation of the R410A of HFC class refrigeration agent, subtend is provided with describing to oil mass of pressing chamber under the situation of contact path 15, and this contact path 15 is supplied with lubricant oil to end of blade seal groove 16b.Be inserted in the end of blade sealing 16a of end of blade seal groove 16b, because the pressure difference of the pressing chamber 51 of interior all sides and the pressing chamber 52 of outer circumferential side, and near the outer circumferential side of end of blade seal groove 16b, as its result, and the pressing chamber 51 of interior all sides between can produce gap 17a.
Have again, consider between two point of contact 18a, the 18b of the 2a of scroll portion of the 4a of scroll portion of the rotary vortex rotary part 4 that forms pressing chamber 5 and fixed scroll member 2, to exist situation to the contact path 15 of end of blade seal groove 16b supplying lubricating oil.Because the back side of the runner plate 4b that is communicated with of contact path 15 is full of the lubricant oil under the head pressure,, contact path 15 also becomes head pressure so facing the pressure of lubricant oil of the position of end of blade seal groove 16b.The result, the gap 17b of the discharge side of comparing with the contact path 15 in the gap of the back side of end of blade sealing 16a and end of blade seal groove 16b (central side), be discharged from gas and be full of, the gap 17c of the suction side of comparing with contact path 15 (outer circumferential side) is full of the lubricant oil of coming by contact path 15.
That is, lubricant oil flows towards the back side of end of blade sealing 16a and the gap 17c of the suction side between the end of blade seal groove 16b by contact path 15, from runner plate 4b, and one towards pressing chamber 5 supplying lubricating oils.
In addition, the pressure in the pressing chamber 5 changes head pressure along with rotation into from suction pressure, still, because the lubricant oil that comes out by contact path 15 is head pressure, so only when pressing chamber 5 is lower than head pressure, to pressing chamber 5 supplying lubricating oils.
Consider above-mentioned situation, multiply by the amount of the pressure reduction of pressing chamber 51 internal pressures and head pressure with respect to length, the result that the amount of the lubricant oil that subtend pressing chamber 5 is supplied with is put in order as shown in Figure 6, this length among two point of contact 18a, the 18b of the 2a of scroll portion of the 4a of scroll portion of the rotary vortex rotary part 4 that forms pressing chamber 5 and fixed scroll member 2, along the length of the 4a of scroll portion of the point of contact 18b of suction side (outer circumferential side) and the rotation scroll portion 4 between the contact path 15.
As can be seen from Figure 6, though with respect to help to reveal, along the length of the 4a of scroll portion of the rotation scroll portion 4 between the point of contact 18b of outer circumferential side and the contact path 15, multiply by the amount of the pressure reduction of pressing chamber 5 internal pressures and head pressure, proportional relation, but, under the situation that end of blade sealing 16a is set, can not free adjustment help the length of revealing.
Therefore, by determining length 14a, can control the lubricant oil of supplying with to pressing chamber rightly with relation shown in Figure 5 in pressing chamber 5 upper sheds of depressed part 14.As its result, because simultaneously can not can reduce, prevent to leak because of refrigerant superheat makes performance, one side can be used as the lubricant oil of slide part, and definite arbitrarily amount and supply that needs is so can provide high efficiency scroll compressor.
In addition, even at refrigeration agent is than under with the situation of freon as the high carbon dioxide more than about 7-10 times of the pressure difference of the freeze cycle in the past of refrigeration agent, also can control the lubricant oil of supplying with to pressing chamber rightly, high efficiency scroll compressor can be provided.
