<p>PURPOSE:To maintain approximately constant lubrication regardless of variation of electromotive force of cell by providing a control means for stopping power supply such that a plunger is stopped at a referential position based a signal being produced upon positioning of the plunger at the referential position. CONSTITUTION:When a plunger 13 is at the end position of reciprocation, a limit switch 25 contacts with the side end portion of a coupling member 21 and turned ON while it is turned OFF when the plunger 13 is positioned at other position. In other word, when an output shaft 18 rotates to start reciprocation of the plunger 13 and when the plunger 13 is positioned at the end position of reciprocation then returned to the end position of reciprocation, the limit switch 25 is turned ON. The limit switch 25 is connected to control section and ON signal is outputted as a detection signal to the control section.</p> |
