Abstract
A viscous fluid supply control apparatus reduces a difference between a primary side pressure of a feeding pump and a secondary side pressure thereof to lessen an internal leak of the feeding pump. The viscous fluid supply control apparatus comprises a viscous fluid supply source, a discharge nozzle for discharging a viscous fluid, a feeding pump for feeding the viscous fluid from the viscous fluid supply source to the discharge nozzle, a first pressure sensor for detecting the primary side pressure of the feeding pump, a second pressure sensor for detecting the secondary side pressure of the feeding pump, and pressure regulation control means for controlling actuation of pressure regulating means regulating the primary side pressure based on detection values obtained by the first and second pressure sensors. The pressure regulation control means controls the actuation of the pressure regulating means such that the primary side pressure of the feeding pump converges on the secondary side pressure thereof.
