A centrifugal lubrication system provides lubrication oil flow to a transmission pocket bearing (18).

The invention relates to a process for preparing lube oil basestocks from lube oil boiling range feeds.

The oil pump is arranged inside a pump chamber, and lubricating oil enters the crankcase through the first oil supply passage.

The method of lubricating an ammonia refrigerant compressor comprises the use of a lubricating oil comprising one or more ether compounds of general formula (I).

The chamber (10) is connected directly with the main lubricating oil duct of the engine.

A further embodiment involves a lubricating oil, a bismuth compound and a molybdenum compound.

The oil pumpdistributeslubricating oilunderpressure.

It is hence useful as a lubricating oil for automotive CVTs.

The spray regulator regulates spraying of lubricating oil from an opening of the oil-supply channel.

These oil systems can provide lubrication oil, seal oil or both.

There is described a hydraulic lubricating apparatus and a hydraulic piston for a dosing system for cylinder lubrication oil, e.g. in marine engines.

The composition is favorable as a lubricating oil composition and useful as a gear oil composition, a lubricating oil composition for paper machines or slide guides, a hydraulic oil, or the like.

The invention relates to the use of 1,1,1,2-tetrafluoroethane for increasing the miscibility of 2,3,3,3-tetrafluoropropene with a lubricating oil, and in particular with a polyalkylene glycol oil.

The phosphorus-free, low ash and light ash formulations may be prepared either as a lubricating oil or as a concentrated additive for a lubricating oil.

The oil supply detector determines whether lubricating oil supply to the transmission (2) is below a predetermined level or not.
