    摘要： This disclosure relates to the art of pressure vessels, more particularly of the type having a cylindrical container, one end of which is closed having a port, and the other end of which defines an open mouth. The container has a deformable bladder of resilient material positioned therein, said bladder having a large mouth with a thickened rim portion in which is molded the lower edge of an annular metal supporting member which extends outwardly from the rim with the free edge portion of said supporting member being secured to the rim of the mouth of the container which is closed by a suitable cover. The thickened rim of the bladder on the inner surface thereof has an inwardly extending annular bead molded integrally therewith in a plane below that of the lower edge of the supporting member to permit folding of the bladder without formation of a sharp pleat.

    摘要： This invention relates to the art of pressure vessels, more particularly of the type having a rigid container with a deformable bladder therein dividing the container into two variable volume chambers, each adapted to receive fluid under pressure. A port is in communication with one of said chambers and a valve member mounted axially on the bladder and molded integrally therewith is associated with said port to close the latter. The valve member is molded into the bladder in such manner that the force exerted by the compressed gas in the bladder will exert a minimum of shearing stress against the molded junction of the valve member to the associated end of the bladder to prevent shearing. In addition, the valve member has a portion extending axially behond the molded junction thereby eliminating impact against such molded junction when the valve member seats to close the port.

    摘要翻译： 本发明涉及压力容器的技术，更具体地说，是具有刚性容器的类型，其具有可变形的囊状物，其将容器分成两个可变容积的腔室，每个腔室适于在压力下接收流体。 端口与所述腔室中的一个连通，并且轴向安装在气囊上并与其一体模制的阀构件与所述端口相关联以关闭气囊。 阀构件以这样的方式模制到气囊中，使得由气囊中的压缩气体施加的力将对阀构件的模制接合部施加最小的剪切应力，以阻止剪切。 此外，阀构件具有沿着模制接合部轴向延伸的部分，从而当阀构件靠近端口时，消除了对这种模制接合部的冲击。

    摘要： The invention relates to a rotary actuator of the type having a movable vane positioned in an arcuate chamber and secured to and extending radially outward from a shaft extending coaxially with the axis of said arcuate chamber. The arcuate chamber forms a central part of a substantially U-shaped chamber having a pair of legs open at their outer end, each chamber receiving a deformable bladder having a closed end adapted to react against opposed ends of the vane, means being provided to permit fluid under pressure to charge said bladders to effect expansion of one of the bladders for consequent movement of said movable vane and the shaft to which it is secured with resultant compression of the other bladder.
