Abstract: Provided is a monitoring apparatus used to monitor lubricating oil inside a compressor. The monitoring apparatus comprises a first capacitance detector (100), a calculation unit, and a determining unit. The first capacitance detector (100) is disposed in a compressor (10) and is completely immersed in lubricating oil (20) inside the compressor (10), and is used to detect a first capacitance value (Cn). The calculation unit calculates a relative dielectric constant of the lubricating oil inside the compressor according to the first capacitance value (Cn) detected by the first capacitance detector (100). The determining unit monitors, according to the calculated relative dielectric constant, whether quality of the lubricating oil (20) inside the compressor (10) encounters an exception. Further provided are a method for monitoring quality of lubricating oil inside a compressor and an apparatus and a method for monitoring a fluid level of lubricating oil inside a compressor.

Abstract: The separating device according to the invention comprises a body delimiting a separating chamber, at least one inlet orifice emerging in the separating chamber and intended to be connected to a discharge orifice of the refrigerant compressor so as to allow a lubricant-refrigerating gas mixture to be introduced into the separating chamber, at least one lubricant outlet orifice emerging in the separating chamber and intended to be connected to a lubricant pan formed in the refrigerant compressor. The separating device comprises a first measuring means arranged to measure the temperature of the lubricant contained in the lubricant pan formed in the refrigerant compressor, and a regulating means arranged to regulate the temperature of the lubricant separated in the separating chamber as a function of the temperature of the lubricant measured by said first measuring means.

Abstract: This refrigeration compressor includes a plurality of compression units, each compression unit having a cylinder head including a refrigerant suction chamber and a refrigerant discharge chamber, a refrigerant distribution device having a distribution pipe and bypass pipes putting the distribution and the suction chambers of the compression units in communication, and a refrigerant discharge device having a discharge pipe and bypass pipes putting the discharge pipe and the discharge chambers of the compression units in communication. The compressor also includes a pressure equilibration pipe arranged to put the suction chambers of at least two compression units and/or the discharge chambers of at least two compression units in communication.

Abstract: In order to form a bead of organic material having a butyl rubber base and a viscosity greater than 35000 poises, the material in a drum is heated and pumped by a reciprocating pump and delivered to an output nozzle via a conduit. A lock chamber in the conduit is delimited by valves. A variable volume chamber connected to the lock chamber or upstream of the lock chamber is able to selectively take in or discharge organic material for maintaining a constant pressure at the nozzle.

Abstract: The invention relates to multiple glazing, a method for obtaining the same and a device for using said method. The glazing contains two sheets of glass separated by a space of dehydrated air and maintained by a cross-braced frame, of which at least the surface in contact with the glass is a butyl and/or polyisobutylene rubber-based mastic and is covered with a peripheral injection, which adheres in a cohesive manner to the mastic of the cross-braced frame.

Abstract: A vane pump in which the ports for passage of highly viscous material pumped are widely dimensioned and the clearances, in particular around the rod which carries the vane, are great. The invention applies to the pumping of materials of the type having a base of butyl rubber and/or polyisobutylene, and in general of materials exhibiting a viscosity greater than 35,000 poises.
