ABSTRACT:
A lubricator intended to feed lubricant, by a short impulse, to a pressure fluid line each time that tapping of pressure fluid is started. In the lubricator, a pressure fluid valve (29) is provided which, after a delay of a fraction of a second, is opened for the passage of pressure fluid when tapping is started. During the delay, a pressure drop results on one side of a lubricant valve (23) while simultaneously a higher pressure prevails in a lubricant reservoir (39) and imposes a movement on the lubricant valve during which lubricant is discharged.
