In a co-rotational scroll apparatus having two interleaving scroll wraps secured to end plates rotating about parallel, non-concentric axes, a precharging device affixed to one end plate and substantially enclosing the scroll wraps and the second end plate. Preferably, the precharging device includes a cup-shaped drive housing secured to one end plate and enclosing the scroll wraps, and a flexible torque-transmitting member connecting between the enclosure member and the second end plate. Apertures are provided in the enclosure member to permit fluid flow into the space enclosed by the enclosure device, with vanes disposed adjacent the apertures to force fluid into the enclosed space during rotation of the scroll wraps. Fluid thus forced into the enclosed space is precharged prior to entering the scroll wraps, being at higher pressure than fluid exterior the enclosed space, improving the operating efficiency of the scroll apparatus.

Cette invention concerne un compresseur à spirales corotatives formé de deux flasques à ailettes spiralées imbriquées qui tournent chacun autour d'axes parallèles légèrement décalés, un des flasque portant un dispositif de précharge encerclant le second flasque et les ailettes spiralées sur sensiblement toute leur hauteur. De préférence, ce dispositif comprend une coupelle d'entraînement fixée à un des flasques et encerclant les ailettes spiralées, et un élément transmetteur de couple flexible entre ladite coupelle et le second flasque. Cette coupelle comporte des ouvertures permettant au fluide de pénétrer dans la zone fermée par elle, ouvertures à côté desquelles sont prévues des aubes servant à forcer le fluide dans cette zone lorsque les flasques à spirales tournent. Ainsi, le fluide précomprimé avant qu'il ne pénètre entre les ailettes spiralées est en surpression par rapport à la pression régnant à l'extérieur de la zone fermée, ce qui a pour effet de rehausser le rendement du compresseur.
