摘要
A foam dispensing gun has a body with a depending handle. The body has two passageways divided into forward and rearward portions by an intermediate chamber. A hose connector and duck-bill one-way valve are mounted in the rearward portion of each passageway, and a valve member extends through both the forward and rearward portions of each passageway. The valve member has a conical needle valve mating with a conical valve seat that opens directly to the nose of the body. A trigger lever is pivotally mounted in the chamber and engages the valve members to open and close the valves. A disposable nozzle with a mixing chamber and outlet is attached about the nose of the body by resilient arms engaging with ears extending from the body.
