text: respectively having a high pressure portion and a low pressure portion on opposite sides of said valve seat, said valve seat having a face directed toward said high pressure portion, a valve mounted for swinging movement in said high pressure conduit portion, said valve being movable between a closed position in which said valve is peripherally engaged to said valve seat and an open position, an actuating shaft secured to sald valve and mounted to said frame for rotation, a motor mounted to said frame, a motor-driven shaft operatively connected to said motor, a clutch operatively connected between said driven shaft and actuating shaft,
text: A valve structure for a suction system comprising: a frame and a conduit secured to said frame, said frame having a closed chamber adjacent to said conduit, said chamber being separated from said conduit by a dust-tight partition, said conduit having a peripheral valve seat therein, said conduit respectively having a high pressure portion and a low pressure portion on opposite sides of said valve seat, said valve seat having a face directed toward said high pressure portion, a valve mounted for swinging movement in said high pressure conduit portion, said valve being movable between a closed position in which said valve is peripherally engaged to said valve seat and an open position, an actuating shaft secured to said valve and mounted to said frame for rotation, a motor mounted to said frame, said motor running in a single direction, said actuating shaft passing through said partition and extending on both sides thereof, a motor-driven shaft operatively connected to said motor, a clutch operatively connected between said driven shaft and actuating shaft, said clutch comprising a fixed clutch portion and a movable clutch portion, said fixed portion being secured to said driven shaft, said movable clutch portion being positioned on said actuating shaft, said driven and actuating shafts being positioned on the same axis in spaced apart relation, said clutch portions being coaxial of the respective shafts, said movable clutch portion being slideable axially on said actuating shaft between a first position in which said movable clutch portion is engaged with said stationary clutch portion and a second position in which said clutch portions are spaced apart and disengaged, first means connected to said movable clutch portion for selectively engaging and disengaging said clutch, means associated with said actuating shaft for preventing said movable clutch portion from rotating about said axis independently of said actuating shaft whereby the rotary motion of said driven shaft is imparted to said actuating shaft when said clutch portions are engaged, a normally closed switch operatively connected to said motor, switch-opening means connected to said actuating shaft for opening said switch when said valve is in said open position, said switch being electrically isolated from said first means, and brake means operatively connected to said motor for preventing said driven shaft from moving when said motor is not running, the engagement of said clutch while said brake means is operated holding said valve in said open position, a time delay means operatively connected in series with said first means for delaying the disengagement of
