Abstract

Commande d'un compresseur rotatif. Une soupape d'aspiration commandée par un piston, lui-même poussé par un ressort, est normalement fermée au moment du démarrage du compresseur. Elle comprend cependant une petite ouverture qui permet un débit limité de l'air vers le compresseur lorsque ce dernier commence à tourner. La dépression due à la fermeture de la soupape d'aspiration provoque une aspiration qui entraîne l'huile d'un bac situé au fond du réservoir d'air vers le compresseur qui peut ainsi démarrer tout en étant refroidi et lubrifié. Le débit de l'air aspiré est régulé par la soupape d'aspiration qui est commandée par un piston disposé dans un cylindre relie à un circuit comprenant des régulateur. Application à la commande et au réglage d'un compresseur refoulant de l'air comprimé dans un réservoir. refoulant de l'air comprimé dans un réservoir.Control of a rotary compressor. A suction valve controlled by a piston, itself pushed by a spring, is normally closed when the compressor is started. However, it includes a small opening which allows a limited flow of air to the compressor when the latter begins to run. The vacuum due to the closing of the suction valve causes a suction which drives the oil from a tank located at the bottom of the air tank towards the compressor which can thus start while being cooled and lubricated. The flow rate of the sucked air is regulated by the suction valve which is controlled by a piston arranged in a cylinder connected to a circuit comprising regulators. Application to the control and adjustment of a compressor delivering compressed air into a reservoir. forcing compressed air into a tank.
