Abstract

PURPOSE: To ensure an outflow due to viscosity of a medium by providing an electromagnetic pump with a temperature compensator varying the width of electrical passage for a pulse which drives a solenoid coil of the pump, after detecting the ambient temperature.
CONSTITUTION: A pulse width setting area 4 determines the time of electrical passage for a pulse. The time of electrical pasage of a pulse transmitted from a linear amplifier 1C3 is determined by the time for charging a condenser C5 through a resistance part R0 consisting of a variable resistance VR2WVR4, resistance R12, R11 and a thermistor TH. Accordingly, the time of electrical passage for the pulse is varied by the thermistor TH according to the ambient temperature. Since a resistance variation of the thermistor TH is a logarithmic one, it is conveniently used to ensure variations of an outflow due to viscosity.
