Abstract: 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, and the air gap 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, attracting the pintle toward the pole piece into the open position. A check valve is disposed in the return path.

Abstract: 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.

Abstract translation: 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。

Abstract: 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.

Abstract translation: 压力涡流雾化器包括具有出口孔和多个切向涡流通道的喷嘴，以及可在枢轴轴承内关闭出口孔的关闭位置和打开出口孔的打开位置之间移动的枢轴。 雾化器还具有一个具有通道的极片，并且当枢轴处于关闭位置时，极片和枢轴由气隙分开。 枢轴和枢轴轴承之间的空间，气隙和通道一起形成返回路径的至少一部分。 当枢轴处于关闭位置时，来自切向漩涡通道的流体通过返回路径排出。 为了打开雾化器，螺线管在通电时产生磁力，将枢轴朝向极片吸引到打开位置。 设置在返回路径中的止回阀在螺线管断电时产生流体背压，以将枢轴推向关闭位置。 流体背压有助于防止枢栓卡在打开位置。

Abstract: A pressure swirl atomizer includes a swirl chamber having an exit orifice, a first section with a first volume, and a second section with a second volume. The second volume is smaller than the first volume, and the exit orifice disposed in the second section. The atomizer also includes a pintle movable to open and close the exit orifice and a plurality of tangential swirl channels disposed about a circumference of the swirl chamber. The reduced volume of the second section reduces the amount of static fluid to be accelerated into a flow pattern, thereby improving spray quality when the exit orifice is initially opened.
