Abstract
A non-lubricated, rotary vane compressor of maximum 10-70 litres/minute capacity, and having a pump body defining a cavity; a rotor having a cylindrical body housed in the cavity; a number of vanes; an inlet and outlet connected to the cavity; and a non-return valve fitted to the outlet.
Description
- The present invention relates to an improved, direct-current or DC vane compressor for a kit for repairing and inflating inflatable articles, in particular tyres, and to a kit comprising such a compressor. The compressor also applies non-limitingly to 12V systems used for a wide range of two- and/or four-wheel vehicle applications, as opposed to hobby applications, and/or to applications that call for a silent-operating, DC compressor with a wide 1-10 bar pressure range and low 7-30 ampere absorption.
- A tyre repair and inflation kit is preferably compact, for easy handling by any user, and silent-operating.
- High delivery pressure enables fast inflation of automobile, motorcycle and even commercial vehicle tyres, but should not increase the size of the kit, for the reason given above, or increase electric current absorption, to avoid overloading the vehicle's electric system, which could discharge the battery and at least temporarily affect the reliability of on-vehicle equipment. Moreover, vehicle electric systems are low-current, which means equipment powered by them must also be capable of efficient, low-current operation.
- A need is felt for compressors of simple design, with a small number of component parts, designed to meet increasing demand in the automobile market for low-cost technology, and which are therefore cheap to produce. A miniaturized compressed-air vane compressor, of improved performance as compared with ordinary alternating compressors and as yet not employed in automobiles, could have big advantages in terms of performance, silent operation, and scope.
- The most obvious hurdles in miniaturizing such a low-cost compressor, which would have to operate with no lubrication, are substantially:
- 1) the materials to use, which must be low-friction, with a sufficient temperature gradient;
- 2) optimum sealing between the assembled parts, in particular between the rotor and stator, between the vanes and rotor, and therefore between the vanes and stator;
- 3) sufficiently good efficiency of the air intake and pressurized air to reduce “parasitic air” circulation inside the compressor.
- The above requirements apply to, and may successfully become characteristic of kits for repairing and inflating inflatable articles, but also apply to other applications as well.
- It is an object of the present invention to provide a vane compressor designed to at least partly meet the above requirements.
- According to the present invention, there is provided a vane compressor as claimed in
claim 1. - A preferred, non-limiting embodiment of the present invention will be described by way of example with reference to the accompanying drawings, in which:
-
FIG. 1 shows a view in perspective of a kit which may be fitted with a compressor in accordance with the present invention; -
FIG. 2 shows an axial section of a vane compressor in accordance with the present invention; -
FIG. 3 shows a section along line inFIG. 2 ; -
FIG. 4 shows a longitudinal section of a component part of theFIG. 2 compressor; -
FIG. 5 shows a section along line V-V inFIG. 4 ; -
FIG. 6 shows a section along line VI-VI inFIG. 4 ; -
FIG. 7 shows performance graphs of a compressor in accordance with the present invention. -
Number 1 inFIG. 1 indicates as a whole a kit for repairing and inflating inflatable articles, and which is purely a non-limiting example of one application of the present invention.Kit 1 comprises acasing 2; a compressor assembly (described in detail below) housed incasing 2; and acanister assembly 3 connected releasably to the compressor assembly, e.g. as described and illustrated in International Patent WO-A1-2008001179 filed by the present Applicant. - More specifically,
casing 2 comprises a substantially parallelepiped-shaped portion 4 for housing the compressor assembly; and a projectingportion 5 projecting from the front ofportion 4 and defining a seat for at least partlyhousing canister assembly 3. - Canister
assembly 3 contains a sealing fluid for repairing tyre punctures, and comprises abottle 6 inverted in use; and a hose 7 connected tobottle 6 to feed the sealing fluid into the tyre. -
Kit 1 also comprises asecond hose 8 connected directly to the compressor assembly to inflate the tyre without injecting sealing fluid; and control means for selecting a repair mode, in which hose 7 andbottle 6 are connected to the compressor assembly, and an inflation mode, in whichhose 8 is connected to the compressor assembly. The control means comprise, for example, avalve 12 switched by aknob 9 oncasing 2, and having two outlets connected tocanister assembly 3 andhose 8 respectively. -
Kit 1 also comprises a power plug for powering a DC, i.e. direct-current, electric motor (not shown) of the compressor assembly from a vehicle electric system; and aswitch 11 for turning the compressor assembly on. - According to the present invention, the compressor assembly comprises a
rotary vane compressor 13 for producing compressed air for injection into the tyre, either viabottle 6 and hose 7 to make repairs, or viahose 8 to simply inflate the tyre. - More specifically,
compressor 13 comprises acylindrical pump body 14 defining acavity 15; arotor 16 housed incavity 15; and aninput shaft 17, of axis A, powered by the electric motor and connected torotor 16. -
Pump body 14 comprises acentral block 18 definingcavity 15; and twoflanges central block 18.Flanges block 18 by a number of pins P; and respective sealing rings G are inserted toseal cavity 15. -
Input shaft 17 has a projectingportion 21 projecting fromflange 19 and connected torotor 16 at least to rotate integrally withrotor 16. On the longitudinally opposite side ofrotor 16 to projectingportion 21,input shaft 17 has apin 23 supported radially onflange 20 by abearing 24. Similarly, projectingportion 21 is supported radially onflange 19 by abearing 25; androtor 16, projectingportion 21, andpin 23 are preferably formed in one piece. - As shown in
FIG. 3 ,compressor 13 defines aninlet 25 and anoutlet 26 connected fluidically tocavity 15, and through which compressed air generated by rotation of the rotor flows. Accordingly,compressor 13 comprises a number of, e.g. four, vanes 27 housed slidably insiderespective seats 28 equally spaced angularly and defined byrotor 16. In the non-limiting embodiment shown,seats 28 are preferably located along chord portions of the cross section ofrotor 16, as opposed to radially. For example,seats 28 extend beyond the geometric centre of the cross section ofrotor 16 with respect to the direction defined by a radius parallel to the sliding direction ofvane 27 insiderespective seat 28. - According to the present invention, air intake is assisted by the inlet combining a through a
hole 29, and aslot 30 which communicates with and is tangentially larger thanhole 29. More specifically,slot 30 is shallower than the thickness offlange 20. - Preferably, the size of
slot 30, the location ofoutlet 26, and the angular distance between each twoconsecutive vanes 27 are such that no angular position of the rotor connectsslot 30 fluidically tooutlet 26. - That is, whatever the angular position of
rotor 16, there is always at least onevane 27 interposed betweeninlet 25 andoutlet 26. As shown inFIG. 3 , preferably one or twovanes 27 are interposed betweeninlet 25 andoutlet 26. -
FIG. 4 shows anon-return valve 31 located in series betweencavity 15 andoutlet 26, and which comprises anannular insert 32 screwed inside aradial hole 33 incentral block 18; atubular body 34 with a threadedstem 35 screwed insideradial hole 33 to rest againstannular insert 32; and a movable disk D inside aseat 36 defined betweenannular insert 32 and threadedstem 35. - More specifically (
FIG. 4 ),annular insert 32 comprises a threaded flange 37 which engagesradial hole 33; and atubular portion 38 projecting axially from threaded flange 37. Threadedstem 35 defines a contoured seat S for housing the whole oftubular portion 38. According to the present invention, the contoured seat has a number ofconduits 39 connected fluidically tooutlet 26 and to apassage 40 inannular insert 32. Preferably,outlet 26 is defined by a preferably cylindrical hole with an axis B; andconduits 39 are straight, and are so located and of such a radius that the geometric surfaces defined by their respective lateral walls interfere with the geometric surface defined by the lateral wall ofoutlet 26, thus forming a number of windows 41 connectingoutlet 26 to conduits 39. - Contoured seat S of
tubular portion 38 is deeper, along axis B, than the height oftubular portion 38, so thatseat 36 of movable disk D is defined between atop face 42 of contoured seat S and anend face 43 oftubular portion 38. Moreover,tubular portion 38 is smaller in diameter than the largest circle tangent to all ofconduits 39, so that, when disk D is raised,outlet 26 is connected fluidically tocavity 15. - In a preferred embodiment of the present invention, at least
pump body 14 andvanes 27 are made of highly wear-resistant, low-friction, non-metal material that can be pressed and/or machined easily, such as carbon-graphite. Generally speaking, other pressable materials of a lower density than metal materials may also be used fornon-return valve 31. - By way of a non-limiting example of the application described,
FIG. 7 shows the flow and energy consumption of a compressor, in accordance with the present invention, featuring a 30mm diameter cavity 15, a 23mm diameter rotor 16, and four vanes. More generally speaking,cavity 15 is less than 50 mm and preferably less than 40 mm in diameter. - As can be seen, consumption is low with respect to flow, and the compressor is compact in size.
- High flow is also and substantially due to leakage being minimized by the design of
non-return valve 31 and the angular position ofslot 30 with respect tooutlet 26.Slot 30, conveniently located according to the work point selected according to rotor rotation speed, compressor size and rotor-stator ratio, also improves air intake and the fill coefficient of the variable-volume chambers ofcompressor 13. - Clearly, changes may be made to the compressor as described and illustrated herein without, however, departing from the scope defined in the accompanying Claims.
- For example, the number of
vanes 27 may range from a minimum of two to a maximum of six. -
Compressor 13 is preferably non-lubricated, i.e. operates dry or with a small amount of lubrication applied during manufacture. In other words, compressor has no lubrication circuit, and draws untreated outside air.
