CONTROL SYSTEM AND CONTROL DEVICE THEREFOR OR THE LIKE

A control device for interconnecting a source of fuel to a burner, the control device having a valve seat and a movable valve member for controlling the valve seat. A movable selector is carried by the control device and a clutch is adapted to interconnect the selector to the valve member, the clutch having means for moving the valve member from an "off" position to a full "on" position thereof, as the selector is moved in one direction from its "off" position to a first position thereof. The clutch keeps the valve member in the full "on" position thereof as the selector is moved in the one direction from the first position thereof to a second position thereof. The clutch thereafter moves the valve member from its full "on" position to a reduced "on" position thereof as the selector is moved in the one direction from the second position thereof to a third position thereof, the clutch being adapted to move the valve member from the reduced "on" position thereof back to the full "on" position thereof as the selector is moved in a direction opposite to the one direction from the third position thereof to the second position thereof.
