ABSTRACT:
A drain discharge device for discharging effluent comprises a valve with a single outlet and a plurality of inlets that selectively connects the single outlet to one of inlets in turn. The inlets, each of which corresponds to an outlet of an effluent discharging device, such as an air compressor or an after cooler, are each sequentially connected to the single outlet in order to drain effluent. Due to the sequential connection of the drain points to the outlet, the drain discharge device operates irrespective of air pressure differences at the drain points. In addition, since each drain point is connected to the outlet in sequence, the system avoids clogging by particulate foreign substances or lubricants. One embodiment discloses a device having a single valve serving three or more inlets. Embodiments employing a rotary ball valve and a linearly moving valve are both disclosed. In one ball valve embodiment, inlets and outlet are in the same plane. In a further ball valve embodiment, the inlets are all in one plane, and an axis of the outlet is orthogonal to this plane, and rotation of the ball valve is about the axis of the outlet.
