Abstract: A nozzle for injecting liquid includes a nozzle body defining a flow channel and a swirl ante-chamber in fluid communication with the flow channel. An injection point orifice is defined in the swirl ante-chamber. The flow channel feeds into the swirl ante-chamber to impart a tangential flow component on fluids entering the swirl ante-chamber to generate swirl on a spray issuing from the injection point orifice. A second flow channel can be included in fluid communication with the swirl ante-chamber. The second flow channel feeds into the swirl ante-chamber in cooperation with or in opposition to the first flow channel. The first flow channel, second flow channel, and swirl ante-chamber are configured and adapted to adjust spray angle of a spray issuing from the injection point orifice by varying flow apportionment among the first and second flow channels.

Abstract: A sealing device is provided for use with an assembly having radially inner and outer parts in fluid communication and movable relative to one another. The sealing device includes a first annular lip which defines an opening for receiving the radially inner part, and an annular channel disposed radially outward of the opening. The first annular lip is configured and adapted for deformation and compressive sealed engagement with the radially inner part while permitting movement of the radially inner part relative thereto. An annular body integrally formed with the first annular lip of the sealing device defines an interior space in communication with the annular channel and the opening. The annular body extends radially outward of the first annular lip and is configured and adapted for sealed engagement with the radially outer part.

Abstract translation: 密封装置用于与径向内部和外部部分流体连通并可相对于彼此移动的组件使用。 密封装置包括限定用于接收径向内部部分的开口的第一环形唇缘和设置在开口径向外侧的环形通道。 第一环形唇缘被构造成适于与径向内部部分变形和压缩密封接合，同时允许径向内部部分相对于其移动。 与密封装置的第一环形唇缘一体形成的环形体限定了与环形通道和开口连通的内部空间。 环形体从第一环形唇缘径向向外延伸，并被构造成适于与径向外部部分密封接合。
