Vynález sa vztahuje na kompresor, hlavně zapuzdrený hermetický chladivový kompresor, którý má na převod rotačného pohybu od motora na posuvný pohyb piesta vo válci použitú ojnicu, ktorá je uložená v pieste pomocou piestneho čapu, pričom ojnica je použita v kombinácii s valcom, ktorý je rozoberatelným sposobom připevněný na nosnú časť kompresora, t. j. válec netvoří s nosnou časťou kompresora jeden odliatok. Sú známe konštrukcie hermetických kompresorov, ktoré majú; použitú ojnicu a ktoré sú popísané v AO ě. 217 470.
Nevýhodou tohto riešenia je vysoká technologická náročnost, výroby gúTóvého kíbu ojnice a gulovej pánvy, pričom je obtiažné vyrobit zostavu piest—ojnica tak, aby sa dosiahla požadovaná životnost.
Vyššie uvedené nedostatky odstraňuje kompresor podía vynálezu, ktorého podsta^ tou je, že ojnica je spojená s piestom, uloženým vo válci pomocou oka ojnice priamo nasunutého na piestny čap którý má zhodný priemer ako vnútorný priemer oka ojnice.
Pokrok vynálezu spočívá v tom, že oko Ojnice može mať minimálny potřebný priemer, čím sa' dosahuje značnej úspory miesta a hmotnosti rotujúcich častí. Zároveň sa dá nastaviť potřebná velkosť škodlivého priestoru posunom valca v smere jeho osi aj pri použití roznych typov kompresorov, alebo pri použití roznych chladív a pri tých- to prednostiach je výroba ojnice, piesta a piestneho čapu klasická, t. j. dosahuje sa známým a jednoduchým spůsobom výroby.
Vynález je vysvětlený na výkrese, kde na obr. 1 je znázorněný motorkompresor v plášti kompresora a na obr. 2 je rez cez piest a válec motorkompresora. V plášti kompresora 1 je na pružinách 2 zavesený motorkompresor, którý sa skládá z nosnej časti 3 kompresora, na ktorej je upevněný válec 4, v ktorom sa pohybuje piest 5, poháňaný pomocou ojnice 6, spojenej s piestom 5, uloženým vo válci 4, pomocou oka 9 ojnice 6 na piestny čap 10, którý má zhodný priemer ako vnútorný priemer oka 9 ojnice 6. Na válci 4 je ventilová doska 11 a tesnenie 12 valca 4, ako aj tesnenie 13 hlavy 14 s hlavou 14 valca 4, ktoré sú připevněné k valcu 4 pomocou skrutiek 15, alebo iným rozoberatelným sposobom. Válec 4 sa připevňuje k nosnej časti 3 pomocou pátiek 17 skrutkami 16, prechádzajúcich otvormi 18, ktoré sú vačšie ako priemery skrutiek 16. Rozdiel medzi velkosťou otvoru 18 a priemerom skrutky 16 slúži pri montáži na posuv valca 4, čím sa vymedzuje velkosť . škodlivého priestoru kompresora.
Toto riešenie umožňuje velkú variabilnost vo výrobě různých výkonových velkostí kompresorov, hlavně v hromadnej výrobě, pri súčasnej výrobě různých typov kompresorov.
The object of the invention can be used in the construction and manufacture of a series of hermetic compressors, which has a high degree of typing, unification, ie, it has a large inheritance of parts and which is produced in large series. This solution makes it possible to reduce the size of the compressor, reduce its weight and reduce the number of components required for many compressors.
239558 axis, from 239558
BACKGROUND OF THE INVENTION The present invention relates to a compressor, in particular an encapsulated hermetic refrigerant compressor, which has a connecting rod disposed in a piston by means of a piston pin in order to convert the piston movement of the piston in the cylinder. that is, the cylinder does not form a single cast with the compressor support portion. There are known designs of hermetic compressors they have; the connecting rod used and which are described in AO ě. 217 470.
The disadvantage of this solution is the high technological complexity, the production of the gusset joint of the connecting rod and the ball pan, and it is difficult to produce the piston-rod assembly so as to achieve the desired service life.
The aforementioned drawbacks are eliminated by the compressor according to the invention, the principle of which is that the connecting rod is connected to a piston mounted in a cylinder by means of a connecting rod eye directly mounted on a piston pin which has the same diameter as the inner diameter of the connecting rod eye.
Advantage of the invention is that the connecting rod eye can have a minimum required diameter, thereby achieving considerable savings in space and weight of the rotating parts. At the same time, the required size of the harmful space can be adjusted by moving the cylinder in the direction of its axis even when using different types of compressors, or by using different coolants, and with these advantages the production of the connecting rod, piston and piston pin is classic, ie is achieved by a known and simple production method .
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows the motor compressor in the compressor casing and FIG. 2 shows the piston and the motor compressor cylinder. A motor compressor is suspended on the springs 2 in the compressor casing 1, which consists of a compressor support part 3, on which a cylinder 4 is mounted, in which the piston 5 is moved, driven by a connecting rod 6 connected to the piston 5 mounted in the cylinder 4 by means of of the connecting rod 6 on the piston pin 10, which has the same diameter as the inner diameter of the connecting rod eye 9. On the cylinder 4 there is a valve plate 11 and a seal 12 of the cylinder 4 as well as a seal 13 of the head 14 with the cylinder head 14 which are attached to of the cylinder 4 by means of screws 15, or by another removable method. The cylinder 4 is attached to the support part 3 by means of bolts 17 through the bolts 16 passing through the apertures 18 which are larger than the diameter of the bolts 16. The difference between the size of the aperture 18 and the diameter of the bolt 16 serves to mount on the displacement of the cylinder 4, thereby defining the size. damaging space of the compressor.
This solution allows great variability in the production of various compressor output sizes, mainly in mass production, while producing different types of compressors.
