Certain exemplary embodiments can provide a system, machine, device, and/or manufacture that is configured for operably releasing condensate from a condensate-producing unit without allowing a substantial quantity of gas to enter the condensate-producing unit and/or a substantial quantity of gas to flow through the system, machine, device, and/or manufacture.

An automatic drain discharge utilizing a vertically movable float to activate a diaphragm of a pilot valve to drive a drain plug. The inner diameter at the bottom of a case is gradually decreased from upper to lower positions. A bottom surface of a communication hole of a drain housing provided in an opening of the case has an inclined surface inclined toward a drain discharge hole. An outer marginal portion which is positioned at the uppermost position in the bottom surface of the communication hole is in the same plane as or lower than a marginal portion which is positioned at the lowermost position in an inner circumferential surface of the case and adjacent to the opening.

A buoyant float including a body having an interior defined in part by a side wall and a bottom extending inward from the side wall. The side wall has an upper edge defining an open top of the body. The float includes a cover sized and shaped for covering the top of the body. The cover attaches to the body to maintain the cover in position relative to the body to cover the open top. The cover has a tubular skirt extending downward and around the upper edge of the body side wall when the cover is in position covering the top of the body. An air pocket is created at an interface between the cover and the body when the float is positioned in liquid to isolate the interface from the liquid and prevent liquid from entering the hollow interior of the body through the interface.

The electric machine has a casing housing a stator and a rotor and containing a gas, and a dryer for the gas. The dryer is connected to the casing. The dryer includes a separation group, for separating humidity from the gas, a water accumulator, for at least temporally accumulating water discharged from the separation group, at least a detector for the water contained in the water accumulator.
