Title (EN) OIL LEVEL SIGNALLING DEVICE FOR COMPRESSOR AND OIL MANAGEMENT APPARATUS, WITH REMOVABLE DETECTION AND CONTROL UNIT
(FR) DISPOSITIF DE SIGNALISATION DE NIVEAU D'HUILE POUR COMPRESSEUR ET APPAREIL DE GESTION D'HUILE, COMPORTANT UNE UNITÉ DE DÉTECTION ET DE COMMANDE AMOVIBLE
Abstract:
(EN) An oil level signalling device (1) for an oil-lubricated compressor (10) comprises a main body (2) in which is formed a detection chamber (4) and a fluidic communication path (420) between the compressor and the detection chamber. A floating element (6) is enclosed in the detection chamber (4) and is suitable to vary its position as a function of the amount of oil. A detection and control unit (7) is removably anchored to the main body (2) and is suitable to detect a position of the floating element (6) and to generate an oil level signal as a function of the position of the floating element (6). An oil management apparatus (1') regulates the flow of oil in the compressor (10) as a function of the oil level signal.
(FR) La présente invention concerne un dispositif de signalisation de niveau d'huile (1) pour un compresseur lubrifié par huile (10) qui comprend un corps principal (2) dans lequel est formée une chambre de détection (4) et un trajet de communication fluidique (420) entre le compresseur et la chambre de détection. Un élément flottant (6) est logé dans la chambre de détection (4) et est adapté pour que sa position varie en fonction de la quantité d'huile. Une unité de détection et de commande (7) est ancrée de façon amovible sur le corps principal (2) et est adaptée pour détecter la position de l'élément flottant (6) et pour générer un signal de niveau d'huile en fonction de la position de l'élément flottant (6). Un appareil de gestion d'huile (1') régule l'écoulement d'huile dans le compresseur (10) en fonction du signal de niveau d'huile.
