摘要： A fluid pressure regulator with a no-drain valve, characterized in that - when the fluid pressure decreases at the regulator's flow inlet to pre-set level, a no-drain spring means of the regulator, overcomes the force exerted by the fluid pressure upon the regulator's no-drain valve component and a protruding shoulder formed around its circumference, pushing a no-drain piston assembly of the regulator and stresses its no-drain valve component towards an exit flow control opening formed in the regulator, to the fully closed state of the regulator's no-drain valve component; and upon an ongoing increase of the fluid pressure at the flow inlet to a pre-set level that is still lower than the designed regulated pressure of the regulator or at most equal to the designed regulated pressure of the regulator, the force that the fluid pressure exerts on the protruding shoulder surface area formed around the circumference of the regulator's no-drain valve component, overcomes a no-drain spring means and propels the regulator's no-drain piston assembly and with it, the no-drain valve component, upon a bushing component within a cylinder assembly and through its second, open opposite end of that cylinder assembly, while opening an exit flow control opening to fluid passage from the flow inlet of the regulator to its flow outlet; and with a further increase of the fluid pressure at the flow inlet to a level higher than the designed regulated pressure of the regulator, and in order to control the flow through the regulator towards the flow outlet from its housing assembly, the regulator's no-drain piston assembly drives a bushing component carried upon a rod component to move together - the regulator's no-drain piston assembly and its piston assembly, towards a flow control opening formed in the regulator's housing assembly.
摘要翻译：一种具有无排水阀的流体压力调节器，其特征在于当流体压力在调节器的入口处降低到预设水平时，调节器的无排放弹簧装置克服了流体压力施加的力调节器的无排水阀组件和围绕其周边形成的突出的肩部，推动调节器的无排水活塞组件，并将其无排水阀组件向形成于调节器中的出口流量控制开口施加到完全关闭状态的调节器无排水阀组件; 并且在流入口处的流体压力持续增加到仍然低于调节器的设计调节压力或至多等于调节器的设计调节压力的预设水平时，流体压力在形成在调节器无排水阀部件周围的突出的肩部表面区域上施加压力，克服了无排水弹簧装置，并推动调节器的无排水活塞组件和无排水阀组件在套管并且通过其气缸组件的第二开放的相对端，同时为从调节器的流入口到其流出口的流体通道打开出口流量控制开口; 并且在流入口处的流体压力进一步增加到高于调节器的设计调节压力的水平，并且为了控制通过调节器朝向其壳体组件的流出口的流动，调节器的无排水活塞组件驱动承载在杆部件上的套管部件一起移动 - 调节器的无排水活塞组件及其活塞组件朝向形成在调节器壳体组件中的流量控制开口。
