Vynález sa týká odmeraej nádoby chladivá, vhodnéj najma pra prenoenú plniacustanicu kompresorových chladiacioh zariadení, pozostávajúcej z odmernáho valca a sta-voznaku, ktorá oba sú usporiadaná medzi hornou přírubou a dolnou přírubou, kde stavo-znak Je β vnútoraým priestorom odmernáho valca přepojený horným spojovacím kanálomusporiadaným v homej přírubě a dolným spojovacím kanálom usporiadaným v dolnej pří-rubě.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metered refrigerant container, particularly suitable for transferring a compressor cooling device comprising a metering cylinder and a vehicle, both of which are disposed between the upper flange and the lower flange, whereby the β internal space of the metering cylinder is coupled by an upper connecting channel. in the upper flange and the lower connecting channel arranged in the lower side.

Fodl'a známého stavu techniky bývajú odmerné nádoby horeuvedenáho druhu konstruo-vané rozoberatelne, a to tak, Se odmerný válec a rúrka stavoznaku sú pomocou skrutiektesne zovreté medzi obomi přírubami, pričom vnútomý priestor odmernáho valca je sostavoznakom přepojený jednoduchými spojovacími kanálmi. OdvzduSnovací ventil je vy- , tvořený ako samostatný funkčný orgán v homej prlrube odmeraej nádoby. Chladiace ‘ médium, ktorým je naplněná odmerné nádoba, má obvykle tú vlastnost, Se velmi lehkopreniká netesnosťami. Z tobto hlediska je relativné velká tesniaca plocha odmeraejnádoby a stavoznaku určitou nevýhodou. Nevýhodou je aj to, Se pri opravě samotnéhostavoznaku třeba rozobrať celú odmeraú nádobu.In the prior art, volumetric containers of the aforementioned type are designed to be disassembled, such that the metering cylinder and the level gauge tube are clamped between the two flanges in a screw-like manner, the internal space of the metering cylinder being connected by simple connecting channels. The vent valve is designed as a separate functional body in the top of the measuring container. The cooling medium, which is a filled measuring container, usually has the property of being very light-leaking. In this respect, the relative large sealing surface of the meter and the level indicator is a disadvantage. The disadvantage is also the fact that the whole measuring container must be disassembled when repairing the hinge mark itself.

Uvedené nevýhody odstraňuje odmerné nádoba chladivá podlá vynálezu, ktoráhopodstata spočívá v tom, Se v homej prírube Je súosovo a rúrkou stavoznaku z homejstrany usporiadaná skrutková zátka, ktorá je zároveň uspSsobená ako teleso odvzduS-ňovacieho ventilu. Medzi vnútoraým čelom skrutkovej zátky a jemu protilehlým vnútor-ným čelom homej tesniacej zévitovej objímky je vytvořená válcová komůrka, do ktorejje zaústěný horný spojovací kanál a ktorej světlý priemer je aspoň taký velký, akoje vonkajSi priemer rúrký stavoznaku. Výhodou odmeraej nádoby podlá vynálezu je, Se sa jej teaniace plochy obmedzililen na homu a dolnu časť stavoznaku, ktorý je l'ahko montovatelný bez nutnosti ro-zobratia ostatných častí odmeraej nádoby, pričom sa niektoré prvky, nachádzajúce sav spoji homej príruby so stavoznakom, účelne využívájú v kumulovaných funkciách,pri zjednoduáenej konátrukcii odmeraej nádoby. Příklad vyhotovenia odmeraej nádoby podlá vynálezu je znázorněný na výkrese,na ktorom obr. 1 představuje jej narýsný rez a obr. 2 detailný rez v mieste A z obr. 1.The above-mentioned disadvantages are eliminated by the volumetric refrigerant container according to the invention, which essentially consists of a screw plug arranged coaxially in the top and a tube of the level indicator, which is also arranged as a vent valve body. A cylindrical chamber is formed between the inner face of the screw plug and the inner face thereof opposite the upper face of the upper sealing ring, into which an upper connecting channel is formed and whose light diameter is at least as large as the outer diameter of the tubular level indicator. The advantage of the metering container according to the invention is that the surface of the measuring container is limited to the upper and lower parts of the level gauge, which is easy to mount without the need to remove the other parts of the measuring container, with some of the elements present in the connection of the upper flange with the level indicator being expediently used in cumulative functions, with simplified construction of the measuring container. An example of an embodiment of a metering vessel according to the invention is shown in the drawing, in which Fig. 1 is a cross-sectional view thereof and Fig. 2 is a detailed sectional view of A of Fig. 1.

Odmerné nádoba chladivá pozostáva z odmernáho valca _1, na homej straně ktoré-ho je privarená horná příruba j2a na dolnej straně ktoráho je takisto privarená dol-ná příruba J. Medzi obidvomi přírubami J2, j_je pomocou homej a dolnej tesniacej zá-vitové j ob Jímky _4_ zachytená rúrka stavoznaku V homej prírube 2_ je súosovo s rúr-kou stavoznaku 5 z homej strany usporiadaná skrutková zátka 6j ktorá je zároveňuspSsobené ako teleso odvzduSňovacieho ventiluj., a to tak, Se je v nej vytvořenékuSelové ventilové sedlo, o ktorá sa opiera hrot skrutky, tvoriacej vřeteno tohto 9 ventilu 7_. Medzi vnútoraým čelom skrutkovej zátky J a jemu protilehlým vnútoraýmčelom homej tesniacej zévitovej objímky j^sa nachádza válcová komorkaj, súosováe rúrkou stavoznaku_5. Do komorky_9_je zboku zaústěný horný spojovací kanál .8, čímje vytvořená priechodná cesta pre plynnú fázu chladivá, spájajúca horaú časť sta-voznaku s hornou častou vnútoraého priestoru odmernáho valca J. Světlý priemervalcovej- komorky 9 Je o niečo vačáí ako je vonkajáí priemer rúrky stavoznaku 5.The refrigerant measuring vessel consists of a measuring cylinder 1, on the upper side of which a top flange 23a is welded on the lower side, which is also welded to the lower flange J. Between the two flanges 12, there are two upper and lower sealing flanges. The captured tube of the level gauge in the upper flange 2 is coaxially aligned with the tube of the level indicator 5 on the upper side of the screw plug 6j, which is also provided as a vent valve body. forming the spindle of this 9 valve 7. A cylindrical chamber is formed between the inner face of the screw plug J and the inner face of the upper sealing ring, opposite to it, which is aligned with the tube of the level indicator 5. An upper connecting channel 8 is formed to the side of the chamber 9, thereby providing a passageway for the coolant gas phase connecting the upper part of the vehicle with the upper part of the inner cylinder of the measuring cylinder J. It is slightly larger than the outer diameter of the gauge tube 5 .

Dolná příruba 3 Je opatřená dolným spojovacím kanálom 10, spojujúcim vnútomý pries-tor odmerného valca 1 so stavoznakom 5, pričom tento dolný spojovací kanál 10, urče-ný pre kvapalnú fázu chladivá, slúSi zároveň aj ako vypúěíací. Pře napúfiťanie chla-divá slúži napúšťací ventil 11. umiestnený v hornéj prírube 2.The lower flange 3 is provided with a lower connecting channel 10 connecting the inner space of the measuring cylinder 1 to the level indicator 5, the lower connecting channel 10 intended for the liquid cooling phase also serving as a discharge. The inflow valve 11 located in the upper flange 2 serves to cool the skin.

Punkčná kumulácia prvkov v mieste skrutkového spoja hornej príruby J s hornoučastou stavoznaku 5 spočívá jednak v spojení funkcie komorky 9 ako prvku, ktorýmThe punctual accumulation of the elements at the point of the bolt joint of the upper flange J with the upper part of the level indicator 5 lies in the connection of the function of the chamber 9 as an element by which
