Abstract
A pressure fluid actuated lubricator having a housing (46), a pressure fluid channel (43, 42, 21) leading from an inlet opening (2) to an outlet opening (7), a reservoir (44) for a lubricant and a discharge device (19) for the lubricant. The reservoir (44) is arranged to be movable by being acted on by the pressure fluid and transfers the pressure force to the lubricant and the discharge device (19). The reservoir is sealed against the penetration of pressure fluid and decreases in effective volume in proportion to the discharged amount of lubricant.
