Abstract:
A constant rate discharge apparatus including a container which contains a material having a given viscosity; a pump unit for supplying said material to a nozzle, and a cylinder for driving an axial member which operates the pump unit, wherein the material in the pump unit can be discharged from the nozzle when the axial member is moved by the cylinder, further comprising a sensor for detecting the moving speed of the axial member provided in the vicinity of the axial member and a controller which conducts pressure adjustment of the cylinder based upon comparison of a manually determined reference moving speed stored in the controller with an output of the sensor, to obtain a constant rate of discharge wherein the pressure is corrected by a predetermined small amount so that the pressure can be returned to an appropriate value after several applications of the material.
