摘要： An applicator for dispensing a liquid conformal coating material onto a substrate. The applicator includes a body assembly with a liquid flow passage having a liquid inlet adapted to receive the coating material and a liquid outlet. A valve seat is positioned between the liquid flow passage and the liquid outlet. A valve stem is mounted in the body assembly for reciprocating movement between an open position and a closed position. The valve stem includes a first end and a second end. The first end of the valve stem engages the valve seat in the closed position to stop flow of the liquid coating material through the outlet and disengages from the valve seat in the open position to allow flow of the liquid coating material through the outlet. A valve actuating mechanism is operative to move the valve stem from the open position to the closed position and is further operative to move the valve stem from the closed position to the open position. A resilient dampening element is operatively coupled between part of the body assembly and the valve stem. The resilient dampening element provides a biasing force against the valve stem as the valve stem moves from the closed position to the open position to reduce rebounding movement of the valve stem toward the closed position.

摘要： An apparatus for dispensing a viscous material includes a dispenser body having an inlet and a discharge orifice. A valve element is mounted for movement in the dispenser body between an open position allowing flow from the discharge orifice, and a closed position preventing flow therefrom. An actuator is coupled to the valve element for actuation between the open and closed positions. A heat exchanger having a serpentine passage and a heater is coupled thereto, wherein the heater is in thermal communication with the dispenser body. The passage is configured to deliver the viscous material to the inlet at a uniform temperature. A method of dispensing a viscous material includes positioning a heat exchanger, having a fluid passage and a heater, in thermal communication with the dispenser body, and heating the material flowing through the fluid passage to a uniform temperature prior to delivering it to the inlet.
