Abstract

The invention relates to a system for keeping oil in the casings of compressors operating in parallel. It comprises a common reservoir 1, the oil return tubes 2 via which the excess oil returns to the reservoir, the reinjection tubes 3 taking oil from the bottom of the reservoir and opening out into the casing of the compressor. The oil is taken back up and sprayed by the expansion of the gases taken from the delivery by the capillary tube 4.

Description

La présente invention concerne un dispositif de maintien permanent d'iluile dans le carter de compresseur, mêr.e travai~- lant en parallèle. The present invention relates to a permanent oil holding device in the compressor housing, mr.e working ~ - lant in parallel.

Dans les systèmes actuels, la capacité d'huile est maintenue - soit par la mise au meme niveau des compresseurs. L quili- brage des pressions dans les carters se fait par tubulure adéquate, de nombreux facteurs secondaires font que la répartition de l'huile est toujours aléatoire. In current systems, the oil capacity is maintained - either by upgrading the compressors to the same level. Since the pressures in the crankcases are balanced by suitable tubing, many secondary factors mean that the distribution of the oil is always random.

- soit par un système à flotteur qui, avec les accessoires nécessaires, rend le dispositif onéreux.- or by a float system which, with the necessary accessories, makes the device expensive.

Le dispositif selon l'invention se réduit à un réservoir placé sous les carters des compresseurs - un tube de tropplein par lequel l'excès d'huile retourne du carter au réservoir - un second tube de section inférieure part du fond du réservoir et aboutit dans le carter. Dans ce tube de remontée aboutit un tube capillaire par lequel arrivent des gaz haute pression pris sur le refoulement. La détente de ces gaz réin jecte en la vaporisant l'huile dans le carter. The device according to the invention is reduced to a reservoir placed under the casings of the compressors - an overflow tube by which the excess oil returns from the sump to the reservoir - a second tube of lower section starts from the bottom of the reservoir and ends up in the housing. In this ascent tube terminates a capillary tube through which high pressure gases taken from the delivery arrive. The trigger of these gases is reinjected by vaporizing the oil in the crankcase.

Le réservoir est commun à tous les compresseurs. Chaque compresseur a un tube de trop-plein et un système de réinsection. The tank is common to all compressors. Each compressor has an overflow tube and a reinsection system.

Facultativement, un clapet anti-retour peut être placé sur le refoulement, en aval de la prise de pression capillaire, arrêtant ainsi le processus de remontée d'huile dans le cas où le compresseur s'arrête et les autres tournent. Optionally, a non-return valve can be placed on the delivery, downstream of the capillary pressure tap, thus stopping the process of raising oil in the event that the compressor stops and the others turn.

Le dessin annexé est une vue du dispositif. Il comporte un réservoir commun N2 1 - les tubes de retour d'huile par gravitations N2 2 - les tubes de réinjection N-0- 3 - les capillaires de prise de pression N2 4.  The attached drawing is a view of the device. It includes a common reservoir N2 1 - the oil return tubes by gravitation N2 2 - the reinjection tubes N-0- 3 - the pressure tapping capillaries N2 4.

Le dispositif objet de l'invention est destiné à répartir l'huile dans les compresseurs d'une centrale frigorifique rnulti-moto-compresseurs. The device which is the subject of the invention is intended for distributing the oil in the compressors of a multi-motor-compressor refrigeration plant.

Le dispositif objet de l'invention peut être utilisé dans tous les cas où il faut maintenir une réserve d'huile dens le carter de machines, à partir d'un réservoir0  The device object of the invention can be used in all cases where it is necessary to maintain a reserve of oil in the crankcase of machines, from a tank 0
