Viscous fluid supply control apparatus

摘要

Provided is a viscous fluid supply control apparatus capable of reducing 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 (22), a discharge nozzle (24) for discharging a viscous fluid, a feeding pump (26) for feeding the viscous fluid from the viscous fluid supply source (22) to the discharge nozzle (24), a first pressure sensor for detecting the primary side pressure of the feeding pump (26), a second pressure sensor for detecting the secondary side pressure of the feeding pump (26), and pressure regulation control means (92) for controlling actuation of pressure regulating means (34) regulating the primary side pressure based on detection values obtained by the first and second pressure sensors. The pressure regulation control means 92 controls the actuation of the pressure regulating means 34 such that the primary side pressure of the feeding pump 26 converges on the secondary side pressure thereof.
