    摘要: A discharge device capable of suppressing pressure fluctuation of a compressed gas supplied to a container in which a liquid material is stored. The device includes a storage container in which a liquid material is stored; a discharge port through which the liquid material is discharged; a pressure control valve that adjusts a pressure of a compressed gas supplied from an external compressed gas source to a desired level; a discharge valve that establishes or cuts off communication between the pressure control valve and the storage container; a control device that controls operation of the discharge valve; a first flow line connecting the pressure control valve and the discharge valve; and a second flow line connecting the discharge valve and the storage container. The device further includes a third flow line branched from the first flow line, and a leak mechanism connected to the third flow line.

    摘要: A dispenser for dispensing a liquid onto a substrate is disclosed. The dispenser includes a liquid supply and a dispenser module. The dispenser module includes a nozzle body having an inlet, an outlet, and a chamber for receiving the liquid. The dispenser module also includes a central valve body attached to the nozzle body that defines a piston chamber and a valve member having a piston portion disposed within the piston chamber of the central valve body and a needle portion extending form the piston portion into the chamber of the nozzle body. The dispenser further includes a heater block for heating the nozzle body. The heater block defines a liquid passage for transporting liquid from the liquid supply to the dispenser, a first surface of the heater block directly contacts the nozzle body, and the entirety of the central valve body is spaced from the heater block.
