Abstract

PURPOSE:To prolong an operation period of a battery in an oil supply equipment which drivers an electro-magnetic pump in respose to a driving signal of a timer control circuit by providing a solar cell which is connected in parallel with the battery, as a power supply. CONSTITUTION:A timer control circuit 15 drives an electromagnetic pump 14 every certain interval to supply oil on a lower face of a trolley wire via a check valve 26. As a power supply for driving the pump, a battery 27 and a solar cell 28 connected to the battery 27 via a reverse current preventive diode are provided in parallel. Because an excess power produced by the solar cell 28 is accumulated in the battery 27, stable driving may be performed in the absence of sunlight and a long term operation may be ensured without replacement of the battery.
