Introduce preferred embodiment of the present utility model below
As shown in Figure 1, compressor is in operation process, refrigerant enters the intakeport 9 of compressor fixed scroll 1 by sucking pipe 10, compress in the selenodont space that fixed scroll 1 and orbiter 2 are formed, compression end of a period cold media air is discharged by the central row gas port of fixed scroll 1, enters upper space, enters motor 8 upper space through the exhaust passage (not providing) of fixed scroll 1 and upper bracket 3, gas after cooling motor 8 enters outlet pipe 12, discharges outside space.
Oil-way system in general scroll compressor is, bottom compressor, oil sump enters the oil inside offering through hole 19 of bent axle by fuel sucking pipe 17 and oil guide piece 18, when crankshaft oil hole 19 is arranged off-centre, so in crankshaft rotating process, due to the effect of centrifugal force, oil in total hole 19 rises to the oil outlet 20 of bent axle head, back pressure oil sump 21 is flowed into after lubrication Moving plate bearing, making the oil of back pressure oil sump be back to oil sump bottom compressor by arranging spill port (return tube), forming an oil circulation.Oil part wherein in back pressure oil sump can enter middle pressure chamber (not providing) by seal ring 11, air aspiration cavity is entered under the agitaion of cross slip-ring 5, but uncontrollable by the oil mass of seal ring, when can not meet rotation speed change, the actual of compression chamber needs oil mass.
Fig. 2 and 3 is oil supplying device of the present utility model closedown within the compressor and open mode, by arranging oil supplying device in the region of back pressure oil sump 21 and seal ring 11, when open, oil inlet hole 22 in oil supply gallery is communicated with back pressure oil sump 21, oil in back pressure oil sump 21 is drained into sound dish end face, thus enters lubrication and sealing that compression chamber realizes cavity.When oil supplying device is in closed condition, although oil supplying device is still in back pressure cavity region, oil inlet hole 22 is plugged, and cannot be communicated with back pressure oil sump and sound dish end face, can not increase the fuel delivery of compression chamber.
The concrete form of implementation of the utility model oil supplying device, as also shown in e.g. figs. 4-7, by arranging oil supply gallery 15 at Moving plate substrate, passage end oil outlet 25 is positioned at substrate front side and is communicated with sound dish surface of contact, passage the other end oil inlet hole 22 is positioned at substrate back, be responsible for being communicated with back pressure oil sump 21 region, oil inlet hole 22 is in the inside of PTFE seal ring 11 moving region simultaneously.When the slide block 13 in oil supplying device because the effect of centrifugal force moves right, now oil supply gallery 15 can be through with the high pressure oil sump of PTFE inside, because the pressure of inspiration(Pi) in back pressure oil sump and Moving plate front exists pressure reduction, lubricant oil in back pressure oil sump 21 can pass through oil inlet hole 22, Oil Guide passage 24 and oil outlet 25 (three is referred to as oil supply gallery 15) are to Moving plate front, in conjunction with the oil groove 27 and 28 of quiet dish end face, can to the friction pair of sound dish end face and compression chamber fuel feeding, thus reduce the friction and wear of friction pair, the sealing of the pump housing can be provided scroll compressor air aspiration cavity fuel feeding simultaneously.
Oil supplying device of the present utility model, Negotiation speed (angular velocity is corresponding with frequency) controls the movement of slide block 13, thus realize opening or closing of oil inlet hole 22, when scroll compressor rotating speed is larger (frequency is higher than 80Hz), because orbiter 2 and slide block 13 belong to eccentric structure relative to crankshaft center, when frequency is large, centrifugal force also synchronously increases, due to square being directly proportional of centrifugal force and frequency, so frequency is higher, the centrifugal force of slide block 13 is larger, thus the frictional force of slide block 13 and Moving plate slide block slot 26 can be overcome smoothly, the frictional force of slide block and PTFE seal ring 11 end face, the spring 14 elastic force sum of slide block 13 afterbody.When the rotating speed of compressor is lower, the centrifugal force due to slide block 13 is less than slide block and Moving plate, the frictional force of PTFE seal ring, spring force sum, and slide block is pressed in left end, realizes the closedown of oil inlet hole 22.
Slide block 13 in the utility model structure can adopt the form of straight pin, is convenient to the resistance processing and reduce sliding process, improves the frequency that oil supplying device is opened.
The control mode of slide block+spring of the present utility model, also can adopt integral structure, is then embedded in the Moving plate back side, realizes opening or closing of oil supply gallery 15.
Those skilled in the art will readily understand, under the prerequisite of not conflicting, above-mentioned each advantageous manner freely can combine, superpose.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
