Embodiment
With reference to Fig. 1, the compressor that is used for steam compressed refrigeration system comprises the Linearkompressor 1 that is supported in the housing 2.Usually, housing 2 seals, and comprises gas access 3 and pressurized gas outlet 4.The gas of uncompressed is flowing in the housing of compressor 1.The gas of these uncompressed is inhaled in suction stroke in the compressor, is compressed between piston head 14 and valve plate 5 when compression stroke, is discharged in the compressed gases manifold 7 via outlet valve 6 then.Pressurized gas is discharged to the outlet 4 of housing from collector 7 via flexible pipe 8.In order to reduce the rigidity effect of outlet pipe 8, this pipe preferred arrangements is circle type or the screw type with the crosscut of described compressor axis of reciprocation.
Can pass through described piston (porose and valve) or by described cylinder cap to the air inlet of compression volume, be divided into and comprise air-breathing and exhaust header and valve at the top.
Broadly say, shown in Linearkompressor 1 have cylinder part and the piston element that connects by main spring.Described cylinder part comprises cylinder chassis 10, cylinder head 11, valve plate 5 and cylinder sleeve 12.Described cylinder part also comprises the stator component 15 that is used for linear motor.Cylinder part is installed main spring away from the end 18 of cylinder head 11 with respect to cylinder part.In the embodiment shown, main spring is the combination of disc spring 19 and leaf spring 20.
Piston element comprises the hollow piston 22 with sidewall 24 and top 14.Bar 26 is connected top 14 and is used between the supporting body 30 of linear motor armature 17.Bar 26 has big flexible portion 28 about hollow piston 22 centers.Linear motor armature 17 comprises permanent-magnet material (as ferrite or neodymium) body, and the permanent-magnet material body has been magnetized to provide one or more and magnetic pole piston to-and-fro motion axis crosscut in cylinder sleeve.End 32 away from the armature supporting body 30 of piston 22 connects with main spring 19,20.
Linearkompressor 1 is installed on a plurality of pendulum springs in housing 2, thereby itself and housing are isolated.In use, the big outer body of Linearkompressor, cylinder part will vibrate along the reciprocating axis of the piston element in the cylinder part.In preferred compressor, to compare with cylinder part, it is very light that piston element specially keeps, and make the vibration of cylinder part compare less with the to-and-fro motion between piston element and the cylinder part.In the illustrated form, Linearkompressor is installed on one group of four pendulum spring 31 that is usually located at periphery.Another kind of pendulum spring configuration mode is shown in the PCT/NZ2004/000108.The end of each pendulum spring is assemblied on the elastic buffer, and buffer is connected with Linearkompressor 1 at an end of each spring, be connected with compressor housing at the other end of each spring.
The concise and to the point now Linearkompressor of describing improved cylinder cap assembly application type of the present invention.Yet, should be appreciated that purposes of the present invention is not limited in the Linearkompressor of shown type and structure.Improvement can be general.
The invention provides a kind of cylinder of Linearkompressor and the manufacture of cylinder head part, this mode has reduced included parts and has improved the reliability that connects, thereby has improved the reliability of manufacturing, cost and compressor.The relevant portion of Linearkompressor shown in Figure 1 further illustrates in Fig. 2 and 3.Figure 4 illustrates slight variant.
In this manufacture, cylinder head cover is included in the main casing frame element of cylinder part 10.Preferably, it is parts and comprising as a whole, for example when making framework and the remaining part whole cast of framework.Therefore, cylinder cap 11 looks like the cap of an end that surrounds cylinder body 35.
Valve plate is on the throne at the cylinder chassis internal fixation so that in the cylinder chassis in the cylinder cap in space part and the cylinder chassis cylinder in space partly separate.Valve plate comprises air release valve hole at least, preferably has the outlet valve that is fixed on a side.
The internal surface of the cylinder part 35 of described shell frame is preferably columniform, the outer periphery of valve plate preferably circular and be dimensioned to and can closely be assemblied in the barrel surface.
The periphery of valve plate 5 is engaged between the end 37 and cylinder chassis of cylinder sleeve 12.Preferably, cylinder chassis comprises annular convex shoulder 39, and the opposite side of valve plate periphery 38 is directly meshed in the end 37 of annular convex shoulder 39 and cylinder sleeve.Alternatively, a plurality of convex shoulder parts can be set around the periphery of valve plate, perhaps can between cylinder chassis and the valve plate 5 or between cylinder sleeve 12 and the valve plate 5 intermediate spacer be set.
Figure 4 illustrates the embodiment who comprises intermediate spacer.In this embodiment, spacer element is not simple cylindrical ring or analog.Replacing spacer element is annular spring 42.Spring 42 and valve plate 5 all mesh between cylinder chassis and cylinder sleeve.Annular spring 42 is against the periphery 38 of convex shoulder 39 and valve plate 5.
The preferred assembling method of these parts of compressor comprises heating cylinder shell frame (normally cast aluminium alloy), valve plate is placed in the reentrant cylindrical cavity against convex shoulder 39 then.Under Fig. 4 embodiment's situation, at first insert the spring spacer element.Then cylinder sleeve 12 brute forces are pushed in the reentrant cylindrical cavity against valve plate, and remain there up to cylinder and shrink thereon.Adopt rational manufacturing tolerances, can stably realize this process, and, realize very effective engagement between cylinder sleeve 12 and the cylinder chassis by cylinder chassis being heated to about 250 ℃ and make cylinder sleeve keep room temperature.
This manufacture can be cancelled many parts, otherwise will fix with cylinder head cover and other bolt or fastening piece, and can eliminate the potential leakage paths by the arbitrary packing ring between cylinder cap and the cylinder end.In compressor of the present invention, can return the compression volume that enters in the cylinder around valve plate from unique leakage paths of cylinder cap.
Cylinder part assembly of the present invention is preferred for only having the situation of outlet valve in the cylinder cap assembly, the Aspirating valves that wherein is used for compressor is included in the top of piston, and gas enters by piston only.Yet described manufacture also can be used for carrying out air-breathing and situation exhaust by cylinder head, guarantees enough sealings but pay particular attention in cylinder cap casing suction side with any place of separating between the exhaust side.
Fig. 4 embodiment of its medi-spring between valve plate and cylinder chassis, guaranteeing has than effective clamp pressure under the situation of mistake for 12 insertion positions of the cylinder sleeve in the cylinder framework.This configuration has attendant advantages, if i.e. piston and valve plate collision in running, valve plate can promote slightly.Can reduce collision noise like this and to any infringement of piston area and the leakage between piston and the linear motor armature.
It is different that configuration of the present invention and cylinder cap or lid are that bolt or other modes are fixed to the common configuration of the resolution element on the cylinder part frame, and the edge of valve plate is sandwiched between cylinder part frame end and cylinder cap or the lid end usually.
