VALVE COMPRESSOR DISCHARGE SCROLL-AND HERMETIC COMPRESSOR

ROTARY DISPLACEMENT COMPRESSOR

In conventional compressors, it has been difficult to satisfy, by a single compressor, both large pressure ratio and large increase/decrease ratio of a working quantity per unit time. Since each compressor has its merits and demerits, there is a limit to utilizing a single compressor over a wide range of applications and a suitable compressor must be selected in accordance with an intended application. Therefore, the present invention makes it possible to take the advantage of a variable displacement that its pressure ratio is great and the advantage of a turbo type that a working quantity per unit time is great. Thus, the present invention makes it possible for a compression apparatus or an internal combustion engine of vehicles to carry out an efficient operation.

A scroll compressor

스크롤 압축기는 선회스크롤을 붙잡기 위한 자전(自轉)방지장치로서 소결금속으로 만든 올댐링(Oldhams ring)을 구비하고 있다. 그리고 올댐링은 소결금속성형의 후속공정인 절삭작업이나 연삭작업에 맞게 모양을 갖춤으로써 결과적으로 올댐링의 생산성이 개선되며 내마모성이 우수하게 된다. 그리고 내마모성이 우수한 경(硬)소결합금을 채용하여 싸고 신뢰도가 높은 스크롤 압축기를 얻을 수 있다. 제1홈(3a)과 제2홈(3b)은 올댐링의 환상(環狀)링(2)의 끝면(end face)(3)에 형성되어 소결된다. 그리고 올댐링의 제조후 높이는 제1홈(3a)이 가장 낮고, 다음 제2홈(3b), 그리고 끝면(3)의 순이다. 공구에서 가장 마모되기 쉬운 모서리부분은 가공부담이 상당량 줄어들고 주로 공구의 측면(side face)에 의해서 가공된다. 그리고 제1홈(3a)부분을 가공하지 않으므로 결국 공구의 비용이 절감된다. The scroll compressor has an Oldhams ring made of sintered metal as an anti-rotation device for catching the turning scroll. In addition, the old dam ring is shaped for cutting or grinding work, which is a subsequent process of sintering metal forming, and as a result, productivity of the old dam ring is improved and wear resistance is excellent. In addition, by employing a light alloy having excellent wear resistance, a scroll compressor having low cost and high reliability can be obtained. The first groove 3a and the second groove 3b are formed on the end face 3 of the annular ring 2 of the old dam ring and sintered. And the height after the manufacture of the old dam ring is the lowest in the first groove (3a), the next second groove (3b), and the end surface (3). The edges most prone to wear on the tool are significantly reduced in machining burden and are mainly machined by the side face of the tool. In addition, since the first groove 3a is not processed, the cost of the tool is reduced.

SPIRAL TYPE MACHINE

L'invention concerne des machines du type à spirale, plus particulièrement pour la compression de fluides gazeux. Au lieu d'utiliser le joint de Oldham classique dans ce type de machine, l'invention fait appel à un dispositif 126 de commande très simple de la rotation de la spirale 52 en orbite par rapport à la spirale fixe 50, qui n'élimine pas la rotation relative, mais la limite simplement à une valeur relativement petite, en combinaison avec des techniques permettant de modifier facilement le contour des enroulements en spirale pour tenir compte de cette rotation relative limitée. Application aux compresseurs, pompes, etc. (CF DESSIN DANS BOPI) The invention relates to machines of the spiral type, more particularly for compressing gaseous fluids. Instead of using the conventional Oldham seal in this type of machine, the invention uses a device 126 for very simple control of the rotation of the spiral 52 in orbit with respect to the fixed spiral 50, which does not eliminate not the relative rotation, but simply limits it to a relatively small value, in combination with techniques for easily modifying the outline of the spiral windings to accommodate this limited relative rotation. Application to compressors, pumps, etc. (CF DRAWING IN BOPI)

In un apparecchio a chiocciole co-rotanti avente due avvolgimenti di chiocciola interfogliantesi fissati a piastre di estremità che ruotano attorno ad assi paralleli non concentrici, per produrre un moto orbitale relativo, un accoppiamento per provocare la rotazione simultanea e per migliorare la stabilità nutazionale dell'elemento a chiocciola. Nella forma di realizzazione preferita, i mezzi di riduzione della nutazione sono costituiti da un accoppiamento di tipo Oldham che impegna organi di estensione su di una delle piastre di estremità della chiocciola e azionano chiavette sull'altra rispettiva piastra di estremità. La loro disposizione angolare è ottimizzata per far si che l'accoppiamento Oldham generi durante la rotazione un carico a momento moderante in opposizione al carico a momento di rovesciamento di almeno uno degli elementi a chiocciola e migliorando perciò la stabilità nutazionale degli elementi a chiocciola. Il carico a momento di moderazione dell'accoppiamento imposto sugli elementi a chiocciola può essere alterato variando la disposizione angolare e radiale del baricentro dell'accoppiamento.

Scroll compressor

The scroll compressor according to the present invention is supported by the pin part of the crankshaft or the inner circumferential surface of the crankshaft by inserting a bush in which the surface receiving centrifugal force, gas force, and gas repulsion force is planar and inserting a surface contact or line contact with the pin part. As the protrusion is formed, the bush is in linear contact with the supporting protrusion, so that even if the pin of the crankshaft is bent, the bush is always in contact with the supporting protrusion, and similar to the reinforced stiffness without increasing the actual shaft diameter of the crankshaft. An effect can be obtained and it can prevent that the swing scroll behavior becomes unstable.

Oiless rotary scroll air compressor antirotation lubrication mechanism

A lubrication apparatus for an anti-rotation assembly of an oiless rotary scroll compressor is disclosed. The scroll compressor includes a stationary scroll element and an orbiting scroll element which orbits about the stationary scroll element in a non-rotational fashion. At least one anti-rotation assembly is provided for preventing relative rotation between the orbiting and stationary scroll elements. The anti-rotation assembly, which includes a first rotational bearing component mounted on the interior of the housing, a second rotational bearing component mounted on the orbiting scroll element and an offset crank member interconnecting the first and second rotational bearing components, is lubricated via a lubrication channel. The lubrication channel extends from a lubrication port disposed on the exterior of the housing, through the first rotational bearing component, thereafter through a channel provided in the offset crank member, thus allowing the lubricating agent (e. g., grease) to reach the second rotational bearing component. The provided anti-rotation assembly can thus be periodically lubricated without significant contact between the lubricating agent and the gas being compressed (e. g., air or refrigerant). Accordingly, any possible contamination of the exiting compressed gas is significantly reduced.
