Description

A kind of double working-chamber flat-moving rotor type compressor

Technical field

The invention belongs to compressor field, relate in particular to a kind of rotor compressor, more specifically to a kind of double working-chamber flat-moving rotor type compressor.

Background technique

Chinese patent application CN200710028138.2 has proposed a kind of translational ring rotary compressor, and it comprises slide plate, end cap, a stator and a translation ring of making translational motion, also is provided with Returnning spring in addition; Described translation ring has the inner hole surface of a circular hole, described stator has a columned outer round surface, described stator is placed among the endoporus of described translation ring, the parallel axes of the axis of the endoporus of translation ring and the outer round surface of stator arranges, the inner hole surface of translation ring all the time with the outer round surface contact matching of stator; Offer the chute of flat on the described stator, described slide plate is placed in the chute of stator and is slidingly matched with it, and described action of reset spring is in the inner of slide plate.When compressor operating, the translation ring is made translational motion under the guiding of parallel moving mechanism, translation device in described parallel moving mechanism and the present widely used scroll compressor is similar, the translation ring in rotation process its endoporus wall all the time with the stator external surface contact matching, slide plate then under the effect of Returnning spring its outer end keep in touch sealing with the endoporus wall of translation ring all the time; Can constitute volume by translation ring, stator, slide plate and end cap etc. can periodically variable work primitive.Above-mentioned compressor belongs to single work cavate compressor, seems less automobile air conditioner compressor that its discharge capacity is limited by strictness for volume and the room air conditioner compressor, therefore is difficult to satisfy those and requires the big device of output air conditioning quantity.

Summary of the invention

The present invention is directed to the existing the problems referred to above of single work cavate translational ring rotary compressor, a kind of double working-chamber flat-moving rotor type compressor is provided, purpose is effectively to improve the air displacement of compressor.

For achieving the above object, the technical solution used in the present invention is: a kind of double working-chamber flat-moving rotor type compressor is provided, and it comprises slide plate, end cap, Returnning spring, a stator and a translation ring of making translational motion; Described translation ring is rotor, it has the inner hole surface of a circular hole, described stator has a columned outer round surface, described stator is placed among the endoporus of translation ring, the parallel axes of the axis of the inner hole surface of translation ring and the outer round surface of stator arranges, the inner hole surface of translation ring all the time with the outer round surface contact matching of stator; Offer the chute of flat on the stator, described slide plate is placed in the chute of stator and is slidingly matched with it, it is characterized in that the outer surface of described translation ring is set to cylindrical surface, and the external cylindrical surface of translation ring is coaxial with the inner hole surface of itself; Also be provided with a cylinder in addition, described cylinder has the inner hole surface of a circular hole, the axis coaxle of the axis of this cylinder bore face and described stator outer round surface, the outer round surface of translation ring all the time with the inner hole surface contact matching of cylinder; In addition, on described cylinder, offer the chute of flat, be mounted with the slide plate that is slidingly matched with it in the described cylinder chute; By translation ring, stator, slide plate and end cap constitute volume can be periodically variable a work primitive, simultaneously constituting another volume by translation ring, cylinder, slide plate and end cap can periodically variable another work primitive, that is this compressor has two active chambers.

A kind of double working-chamber flat-moving rotor type compressor of the present invention, owing to compare with the described single cavity compressor of document CN200710028138.2 above-mentioned, increased an active chamber, therefore increase under the situation of little or constancy of volume at the compressor volume, can effectively increase the discharge capacity of compressor.

Embodiment

Fig. 1 and Fig. 2 show the structure schematic cross section and the working principle schematic representation of a kind of double working-chamber flat-moving rotor type compressor of the present invention respectively.This compressor comprises translation ring 1, stator 2, the first slide plate 3a and the first Returnning spring 4a, cylinder 5, the second slide plate 3b and the second Returnning spring 4b; Described translation ring 1 has inner hole surface and columned outer surface coaxial with this inner hole surface of a circular hole; Described stator 2 has a columned outer round surface, described cylinder 5 has a circular hole inner hole surface coaxial with stator 2 outer round surface, described translation ring 1 is placed between stator 2 and the cylinder 5, the parallel axes of the outer round surface of the axis of the inner hole surface of translation ring 1 and stator 2 is arranged, the inner hole surface of translation ring 1 all the time with the outer round surface contact matching of stator 2, the outer round surface of translation ring 1 all the time with the inner hole surface contact matching of cylinder 5, said contact matching allows to exist matching gap; Offer the chute of flat on the stator 2, the first slide plate 3a is placed in these chutes and is slidingly matched with it; Offer the chute of flat on the cylinder 5, the second slide plate 3b is placed in these chutes and is slidingly matched with it; Need to prove that the number of the first slide plate 3a, the second slide plate 3b can be one, and also can be two can also be a plurality of, equates that with the number of their corresponding chutes first slide plate 3a shown in Figure 1 and the number of the second slide plate 3b are two; As shown in Figure 1, the first Returnning spring 4a is placed in the inner end of the first slide plate 3a, its effect is to make the outer end of the first slide plate 3a be close to the inner hole surface of translation ring 1 all the time, and the second Returnning spring 4b is placed in the outer end of the second slide plate 3b, and its effect is to make the inner of the second slide plate 3b be close to the outer cylinder surface of translation ring 1 all the time; It is to be noted, when compressor operation, the motion mode of translation ring is the translation (see figure 2), in order to see clearly Chu, special translation ring 1 subscript on Fig. 2 shows two stains, from the change in location of stain as can be seen translation ring 1 be to do translation rotation really; In addition, in order to realize translation, can use for reference parallel moving mechanism that present scroll compressor adopts such as cross slip ring parallel moving mechanism, spherical coupling parallel moving mechanism or the like (not shown).The working principle of present embodiment is: when compressor operating, translation ring 1 beginning translation, its internal circular surfaces all the time with the outer surface contact matching of stator 2, its outer cylinder surface all the time with the inner hole surface contact matching of cylinder 5; This moment, the first slide plate 3a was protruding under the effect of the first Returnning spring 4a, and the endoporus wall of the outer end of the first slide plate 3a and translation ring 1 remains contact matching, and the second slide plate 3b inwardly stretches out under the effect of the second Returnning spring 4b; Constituting a volume by translation ring 1, stator 2, the first slide plate 3a and end cap etc. can periodically variable work primitive, then constituting another volume by translation ring 1, cylinder 5, the second slide plate 3b and end cap etc. can periodically variable work primitive, that is this compressor has two active chambers.Obviously, because the increase of the number of active chamber, so a kind of double working-chamber flat-moving rotor type compressor of the present invention can effectively increase discharge capacity.
