Abstract: The invention relates to a pneumatic pressure regulating assembly. The assembly includes a cylindrically shaped housing having a top or cover portion with holes therein. A spindle member extends through and above the housing with the spindle portion above the housing being hollow and having an inlet opening in fluid communication with the hollow interior. A dish shaped member having a central opening is slidably mounted on the spindle member. The dish shaped member has a flange engageable with the top portion of the housing and being in surrounding relation to the holes in the cover portion. The dish shaped member is raisable by air flowing through the housing and the holes in the cover thereof so as to allow a portion of this air to be blown off and the remaining portion of the air to enter the inlet opening of the spindle member. The dish shaped member has a predetermined weight and the pressure is regulated by reason of the dish shaped member assuming different vertical positions which keeps the pressure constant by varying the amount of air blown off.
Abstract translation: 本发明涉及一种气动调压组件。 组件包括具有顶部或盖部分的圆柱形壳体，其中具有孔。 心轴构件延伸穿过壳体并且壳体上方的心轴部分是中空的并且具有与中空内部流体连通的入口开口。 具有中心开口的碟形构件可滑动地安装在心轴构件上。 盘状构件具有可与壳体的顶部接合并且与盖部分中的孔围绕的凸缘。 碟形部件可以通过空气流过壳体和其盖中的孔而升高，以使空气的一部分被吹走，剩余部分的空气进入心轴构件的入口。 碟形构件具有预定的重量，并且由于盘形构件假定不同的垂直位置来调节压力，通过改变吹出的空气量来保持压力恒定。
