    • A fluid-operated apparatus includes a rotary member integral with the fluid-operated rotary body in a stationary member adjacent thereto in end face confronting position with respect to the rotary member. A pair of circumferential grooves within the end face of the stationary member carry respectively, an annular sealing piston for controlling check valve actuation within the rotary member and an annular sealing piston for controlling ventilation of the fluid-operated rotary body by opening the check valve. Fluid passage project through the annular piston and communicate to the end face of the rotary member. The rotary member is provided with check valves within passages corresponding to the passages within the actuator annular piston for controlled supply of compressed fluid to the fluid-operated rotary body. The bores within the rotary member which carry the check valves and form a portion of the fluid passage leading from the stationary member to the fluid-operated rotary body and carry ventilation control pistons operatively disposed with respect to the check valves which ventilate pistons are fluid connected by passages within the rotary member leading to the annular pistons within the stationary member permitting selective ventilation of the fluid-operated rotary body by applying fluid pressure to the ventilation pistons.
    • 流体操作装置包括与相对于旋转构件的端面相对位置相邻的固定构件与流体操作的旋转体成一体的旋转构件。 固定部件端面内的一对圆周槽分别承载用于控制旋转部件内的止回阀致动的环形密封活塞和用于通过打开止回阀来控制流体操作旋转体的通风的环形密封活塞。 流体通道突出通过环形活塞并与旋转构件的端面相通。 旋转构件在对应于致动器环形活塞内的通道的通道内设置有止回阀,用于向流体操作的旋转体控制供应压缩流体。 旋转构件内的旋转构件中的孔,其承载止回阀并且形成从静止构件引导到流体操作的旋转体的流体通道的一部分,并且承载相对于通气活塞流体连接的止回阀可操作地设置的通风控制活塞 通过在通向固定构件内的环形活塞的旋转构件内的通道,允许通过向通气活塞施加流体压力来选择性地通风流体操作的旋转体。
