摘要： Control system for pneumatic control of a cleaning arrangement for dust filters wherein a plurality of tubular filter elements are cleaned by a blast of air forced through the filter elements successively and in the direction reverse to that of filtering air flow. A plurality of quick-opening valves are operatively connected to outlet ports in a housing defining a pressure chamber. An arm is movably mounted in the chamber and has an air passage therethrough from its inner end to its outer end, the outer end being movable over the outlet ports in succession. The arm is moved intermittently by pneumatically operated means including an actuator movable alternately in opposite directions. The inner end of the air passage communicates with a pneumatically operated control valve that is disposed in a pneumatic control circuit including other valve mechanisms operated responsive to movement of the actuator in opposite directions to open and close the pneumatically operated valve, to respectively permit a corresponding quick-opening valve to open, and to seal off the chamber from atmosphere during movement of the arm from one outlet port to the next succeeding outlet port.

摘要： A membrane channel-valve is disclosed, having a switching membrane responsive to the pressure in a switching chamber therein to open or close a conduit to control gas flow between pressure medium intake and outflow connections. The channel-valve is controlled by a conversion valve forming a seal between a control medium intake line and a control medium output line so that when closed there is a static pressure in the intake line and when open there is a gas current flow through the intake line. A jet pump is provided having an exit opening in the control medium intake line and an entrance opening in the switching chamber of the channel-valve, to pressurize the switching chamber during static pressure conditions to close the channel-valve and to provide a low pressure therein during current flow conditions to open the channel-valve.

摘要： A pneumatic dust collection system includes a housing which defines a dust-air chamber portion, a flushing air chamber portion and a clean air portion arranged one above the other. A separating wall between the flushing air chamber and the dust-air chamber is penetrated by fittings for suspending filter hoses in the dust-air chamber portions which communicate through the fittings into the flushing air chamber. A connecting tube extends from the clean air chamber into the interior of each filter hose fitting and the filter hose which is carried thereby and defines an annular flow space between the interior of the hose and the flushing air chamber. This annular flow space may be closed off by an inflatable member which is disposed at the connection of the fitting to the separating wall. At this annular space the connecting tube includes a widened portion around which the flow is diverted and which is located opposite to the inflatable membrane. The interior of the inflatable membrane is connected to an air pressure line and it is inflated to close the annular flow passage between the interior of the filter hoses and the flushing air chamber. The apparatus includes a control system for controlling flushing air to the flushing air chamber and for filling this chamber before the membrane is deflated. An over and underpressure control is connected between the clean air chamber and the dust-air chamber to maintain a selected pressure difference between the clean air chamber portion and the dust-air chamber portion during operation. The flushing air chamber and the control line for supplying the air to the chamber is closed by a rapid depressurizer member which is closed by a signal from a preferred output of a monostable fluid mechanism element. An overpressure in he flushing air chamber causes the depressurizer to open rapidly.
