Abstract (en)
The invention is directed to provide a liquid pump (lubricant circulation or lubricant supply pump) that is capable of lubricating a machine or apparatus even in a case that a passage supplying a liquid (lubricant) is in a vacuum condition. To solve the above, the invention is characterized in a liquid pump (lubricant circulation or lubricant supply pump) for delivering a liquid (lubricant) from a liquid storing portion (lubricant storing portion) to a predetermined position of at least one location, wherein at least one cylinder chamber is formed inside of the pump, a piston is arranged to reciprocate by a driving means in the cylinder chamber, the cylinder chamber is communicated with a liquid (lubricant) delivery port, so that the liquid (lubricant) discharged into a fluid passage communicating with the predetermined position of at least one location, the driving means is provided with a solenoid including an axial portion all of which or at least a part of which is made of a ferromagnetic substance and a solenoid coil that are relatively movable to each other, the axial portion all of which or at least a part of which is made of the ferromagnetic substance and the cylinder chamber are fixed by a predetermined means. <IMAGE>
