Abstract
Disclosed are a liquid (lubricant circulation or lubricant supply) pump and an apparatus using this pump. The pump is capable of lubricating a machine apparatus even when a portion requiring liquid (lubricant) and a route for supplying liquid (lubricant) are in vacuum. The liquid (lubricant circulation or lubricant supply) pump sends liquid (lubricant) from a liquid storage section (lubricant storage vessel) to at least one predetermined position. At least one cylinder chamber is formed inside the pump, and a piston can be reciprocated from one end of the chamber by drive means. A liquid (lubricant) sending opening is communicated with the cylinder chamber, so that liquid (lubricant) can be sent to a circulation passage communicated with at least one predetermined position. The drive means is a solenoid provided with a shaft portion and a solenoid coil that are relatively movable to each other. The whole part or part of the shaft is made of ferromagnetic substance. The shaft that is wholly or partly made of ferromagnetic substance and the cylinder chamber are fixed with predetermined means.
