ABSTRACT:
A liquid actuated switch device including a case that defines an accumulator chamber with upper and lower portions and liquid inlet and outlet openings communicating with the lower portion of the chamber and connected with upstream and downstream sections of flow line delivery, a flow passage through which liquid is forcibly driven, a normally open liquid level actuated switch in the upper portion of the chamber and actuated to close by liquid in the chamber when the level of the liquid in the chamber rises to an actuating level where the pressure on the liquid and on the gases in the upper portion of the chamber are in subsequent equilibrium. The device includes a vent duct extruding between the upper portion of the chamber and the flow passage downstream of the chamber to balance the pressure on the gas in the chamber with the pressure on the liquid downstream thereof.
