Abstract
A device for supplying a lubricant comprises a receptacle to contain the lubricant with an opening arranged in the bottom thereof. A piston member is sealingly displaceable along the walls inside the receptacle and located in initial position near the top of the receptacle. At least one extendable or expandable member is supported by the receptacle at the circumference over the lubricant present in the receptacle with a bottom portion located near and above the piston member which member contains an electrolyte. At least one galvanic element is supported over the electrolyte inside the receptacle, and a flexible member and rupturable support are provided for bringing the galvanic element into contact with the electrolyte. The said extendable or expandable member with the electrolyte present therein and the galvanic element form a separate assembly detachable from the receptacle. The receptacle consists of a bottom part open at the top which may contain the lubricant and a cover capable of closing this portion from the top, so that after removal of the cover, the separate assembly may be taken out of the receptacle.
