Abstract

"CONJUNTO DE VEDAçãO DE EXTREMIDADE DE COMPRESSOR DE AR ESPIRALADO ROTATIVO SEM óLEO". Um conjunto de vedação de extremidade, para um compressor espiralado rotativo, é mostrado. O compressor espiralado rotativo tem um elemento espiralado estacionário com um flange em espiral estacionário e um elemento espiralado orbitante com um flange em espiral orbitante. Um mecanismo de acionamento orbital aciona o elemento espiralado orbitante, em uma órbita em torno do elemento espiralado estacionário, e um dispositivo de mancal não rotativo mantém o elemento espiralado orbitante substancialmente não rotativo em relação ao elemento espiralado estacionário. Os flanges em espiral estacionário e orbitante são encastrados e alojados um no outro, para formarem pelo menos um bolsão de compressão em espiral entre eles. O conjunto de vedação de extremidade forma um selo substancialmente estanque ao ar entre pelo menos um dos flanges em espiral estacionário e orbitante e a base do outro elemento espiralado. O conjunto de vedação de extremidade inclui uma cavidade que se estende para dentro, formada em uma superfície de extremidade de pelo menos um dos flanges em espiral estacionário e orbitante, um elemento compressível, disposto dentro e ao longo da cavidade, e uma vedação de extremidade, que se sobrepõe ao elemento compressível. Preferencialmente, o elemento de vedação de extremidade se estende além da superfície de extremidade, quando o elemento compressível está em um estado não comprimido, o elemento de vedação de extremidade incluindo pelo menos um dentre uma superfície não metálica, um material fluorosint e um produto à base de PTFE, e o elemento compressível incluindo pelo menos um dentre um material elastomérico, um material de borracha de silicone e um material de anel em O resistente a uma alta temperatura."END SEALING ASSEMBLY OF ROTARY SPIRAL SPIRAL AIR COMPRESSOR WITHOUT OIL". An end seal assembly for a rotary spiral compressor is shown. The rotary spiral compressor has a stationary spiral element with a stationary spiral flange and an orbiting spiral element with an orbiting spiral flange. An orbital drive mechanism drives the orbiting spiral element in an orbit around the stationary spiral element, and a non-rotating bearing device keeps the orbiting spiral element substantially non-rotating in relation to the stationary spiral element. The stationary and orbiting spiral flanges are recessed and housed together, to form at least one spiral compression pocket between them. The end seal assembly forms a substantially airtight seal between at least one of the stationary and orbiting spiral flanges and the base of the other spiral element. The end seal assembly includes an inwardly extending cavity formed on an end surface of at least one of the stationary and orbiting spiral flanges, a compressible element disposed within and along the cavity, and an end seal , which overlaps the compressible element. Preferably, the end sealing element extends beyond the end surface, when the compressible element is in an uncompressed state, the end sealing element including at least one of a non-metallic surface, a fluorosint material and a product PTFE base, and the compressible element including at least one of an elastomeric material, a silicone rubber material and a high temperature resistant O-ring material.
