Abstract: The present invention relates to a system which makes it possible to remove undesirable liquids, generally an aqueous phase, which precipitate to the bottom of tanks for storing liquid products. Use is made of a drainage device (30) which comprises a concave body (31), a seat (26), and an interface float (8) which has a plug portion (25). This interface float (8) is designed to sink into the product and to float on the aqueous phase. As the level of the aqueous phase drops, the plug portion (25) settles sealingly on the seat (26), halting the drainage operation since all the accumulated aqueous phase has already been drained off. The drainage system may be automatic or manual. In the former case, use is made of a sensor (12) for detecting the presence of an aqueous phase and commanding the process of opening a shut-off valve (11) and allowing drainage of the accumulated aqueous phase.

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.

Abstract: An expansion chamber is attached between two air compression stages of an air compressor or between an air compression stage and the air holding tank of the air compressor. The expansion chamber has a cylindrically shaped wall with top and bottom portions attached so as to define an enclosed inner chamber. The enclosed inner chamber may have one or more baffle plates located therein. Various designs of baffle plate arrangements provide different air circulating patterns within the expansion chamber. Since the expansion chamber is exposed to the ambient environment, the compressed air heated in the compression process is cooled down in the expansion chamber. This cooling down of the compressed air as well as the expansion of the compressed air as it circulates within the enclosed inner chamber causes any moisture suspended in the compressed air to drop out and go to the bottom of the expansion chamber.
