摘要： An apparatus and method for providing a pressurized air supply (88) to a balance piston assembly (94) to balance an axial load on a gas turbine engine compressor (22). The pressurized air supply (88) can be supplied by a mixing valve (144) mixing a primary (140) and secondary pressure bleed air supply (142) relative to feedback received from the balance piston assembly (94) to maintain a predetermined pressure at the balance piston assembly (94).

摘要： Pumps priming adjustable device, realized with an ejector provided of a suction inlet and an outlet communicating through a conduit for conveying and exhausting a fluid that has been aspired from a pump or from its suction pipe, using the vacuum effect created inside the ejector itself by the flow of compressed air. The suction inlet of said ejector communicating with the pump and/or the pipe through an on-off valve which, with its opening and closing action, permits the flow of fluid aspired from pump or from its pipe into the said ejector or prevents such flow.
To permit the operation of ejector is also provided an external source of compressed air connected to a feeding valve of the ejector, and between said suction inlet and said outlet there is an injection nozzle injecting compressed air into the conduit, having the injection nozzle a predetermined flow section.
The injection nozzle is adjustable in said flow section, which consists of an annular channel in the peripheral wall of said conduit, which in turn being composed of two parts, a first part static and a second part movable, which may be moved towards and/or away from each other to change the flow section of the channel of injection nozzle.摘要翻译： 泵浦起动可调节装置，其由具有吸入口的喷射器和通过导管连通的喷射器实现，所述导管通过导管输送和排出已经从泵或其吸入管吸取的流体，使用在喷射器本身内部产生的真空效应 压缩空气的流动。 所述喷射器的吸入口通过开关阀与泵和/或管连通，该开关阀具有其打开和关闭动作，允许从泵或从其管道吸入的流体流入所述喷射器或防止这种流动 。 为了允许喷射器的操作还提供了连接到喷射器的进料阀的外部压缩空气源，并且在所述吸入口和所述出口之间，存在喷射喷嘴将压缩空气注入到管道中，其中喷射喷嘴具有预定的 流动部分。 注射喷嘴在所述流动部分中是可调节的，其由在所述管道的周壁中的环形通道组成，所述环形通道又由两部分组成，第一部分静止部分和第二部分可移动， 或彼此远离以改变注射喷嘴的通道的流动部分。
