摘要： A pressure swirl atomizer includes a nozzle having an exit orifice and a plurality of tangential swirl channels and a pintle that is movable within a pintle bearing between a closed position that closes the exit orifice and an open position that opens the exit orifice. The atomizer also has a pole piece having a channel, and the pole piece and the pintle are separated by an air gap when the pintle is in the closed position. A space between the pintle and the pintle bearing, the air gap, and the channel together form at least a part of a return path. Fluid from the tangential swirl channels drains through the return path when the pintle is in the closed position. To open the atomizer, a solenoid generates a magnetic force when energized, attracting the pintle toward the pole piece into the open position. A check valve disposed in the return path generates a fluid back pressure when the solenoid is de-energized to push the pintle toward the closed position. The fluid back pressure helps prevent the pintle from getting stuck in the open position.

摘要： A pressure swirl atomizer has a swirl chamber with an exit orifice and a plurality of tangential swirl channels disposed around the circumference of the swirl chamber. A pintle bearing surrounds a pintle. The pintle has a body portion and a nose portion that is narrower than the body portion. The nose portion has a tip that opens and closes the exit orifice and a side that is movable in the pintle bearing. In one embodiment, a return path formed between the nose portion of the pintle and the pintle bearing drains fluid from the swirl chamber when the exit orifice is closed. The nose portion positions the return path closer to a centerline of the atomizer, forcing fluid to swirl in the swirl chamber before draining. Since the fluid does not remain static in the chamber, less energy is needed to increase the fluid velocity and quickly form a desired spray pattern when the exit orifice is opened.
摘要翻译：压力漩涡雾化器具有涡流室，其具有出口孔和围绕涡流室的圆周设置的多个切向涡流通道。一个枢轴环绕一个枢轴。枢轴具有比主体部分窄的主体部分和鼻部部分。鼻部具有打开和关闭出口孔的尖端以及可在枢轴轴承中移动的一侧。在一个实施例中，形成在枢栓的鼻部和枢轴轴承之间的返回路径在出口孔关闭时从涡流室排出流体。鼻子部分使返回路径更靠近雾化器的中心线，迫使流体在排水之前在涡流室中旋转。由于流体在腔室中不保持静止，因此当出口孔打开时，需要更少的能量来增加流体速度并快速形成所需的喷雾模式。
