Abstract A scroll compressor, in which revolving spiral blade part (13) is subjected to an intermediate pressure between pressures on the outlet and inlet sides at the back thereof, is provided with such means as controlling and cooling the abovesaid intermediate pressure with lubricant oil reserved in the lubricant reservoir (26) on which discharge pressure in a closed vessel (1) acts. Lubricant oil to be fed to the compressive part is secured under any pressure conditions and stably fed at any time. The lubricant oil is so cooled as not to cause significant fall of efficiency. Un compresseur à hélice, dans lequel une lame hélicoïdale tournante (13) est soumise à une pression intermédiaire entre les pressions côtés sortie et admission qui règnent au niveau de la partie arrière, comporte des moyens de refroidissement et de régulation de ladite pression intermédiaire, à l'aide d'huile lubrifiante stockée dans le réservoir de lubrifiant (26) et sur laquelle agit une pression de refoulement dans un récipient fermé (1). L'huile lubrifiante devant être acheminée à la partie de compression peut être soumise à n'importe quelles conditions de pression et est acheminée régulièrement à tout moment. L'huile lubrifiante est refroidie de manière à ne pas provoquer de baisse importante de rendement.
