A shower head having a stem; a spray head coupled to the stem; a mixing valve located within the stem or the spray head, the mixing valve having a first valve member assembly for controlling a first fluid flow to a mixing chamber and a second valve member assembly for controlling a second fluid flow to the mixing chamber. Each valve member assembly includes a spool, a first valve member on the spool that engages with a first valve seat in a closed position and a second valve member on the spool that engages with a second, separate, valve seat in the closed position. An electrically powered first motor is located within the stem or the spray head. The first motor is coupled to the first valve member assembly to control movement of the first valve member assembly to control the flow of the first fluid to the mixing chamber.

Systems operable to blend at least one finished gasoline from a refined petroleum product comprising at least one neat gasoline with ethanol and optionally butane utilizing a blend model that calculates a volumetric blend ratio comprising at least one neat gasoline, ethanol and optionally, butane. The blend model incorporates estimated values for the octane number and the volatility of the ethanol and butane when calculating the volumetric blend ratio.

A fuel selector for use with a dual fuel generator includes a selector plate, a first fuel valve assembly positioned adjacent the selector plate and actuatable between an ON position and an OFF position to selectively control a first fuel flow to an engine of the dual fuel generator, and a second fuel valve assembly positioned adjacent the selector plate and actuatable between an ON position and an OFF position to selectively control a second fuel flow to the engine of the dual fuel generator. A selector switch coupled to the selector plate is linearly translatable from a first position to a second position, so as to enable positioning of only one of the first fuel valve assembly and the second fuel valve assembly in the ON position at a given time, such that the first and second fuel valve assemblies cannot be in the ON position concurrently.

A water delivery device that includes a body having a cold water inlet, a hot water inlet, and an outlet; a mixing valve in the body, and a touchscreen user interface on a surface of the body. The mixing valve includes a housing having a mixing chamber that is fluidly connected to the outlet, a first flow control valve moveably disposed in the housing to control a cold water flow from the cold water inlet to the mixing chamber, and a second flow control valve moveably disposed in the housing to control a hot water flow from the hot water inlet to the mixing chamber. The touchscreen user interface allows a user to control a temperature and/or a flow rate of water from the outlet by controlling the first and second flow control valves.

A shower head that includes a movable handset, a mixing valve, and an electric heater. The movable handset includes a stem configured to detachably engage a shower head dock, and a spray head coupled to the stem and configured to discharge water. The mixing valve is disposed within the movable handset and includes a housing including a waterway located therein for water to flow through, a first flow control valve located within the housing and configured to control the flow of hot water to the spray head, and a second flow control valve located within the housing and configured to control the flow of cold water to the spray head. The electric heater is disposed within the movable handset and configured to heat at least part of the housing to an elevated temperature sufficient to kill organisms within the waterway.

A connector for transferring fluid and method therefor. The connector may have a first port and a second port which may be coupled together at a main channel with a valve element therein controlling fluid flow through the first port. The first port joins the main channel to provide a fluid path around the valve element and through the second port.

A faucet assembly including a handle that rotates about a rotational axis extending perpendicular to an angled interface for adjusting a water parameter.

The hot and cold water mixing valve device includes a hot and cold water mixing valve unit; a flow control valve unit; a valve device main body; a hot and cold water mixing valve housing; and a flow control valve housing; and wherein the valve device main body includes: a hot water passageway permitting communication between only the hot water inlet of the valve device main body and the hot water inlet of the hot and cold water mixing valve unit; and a cold water passageway permitting communication between only the cold water inlet of the valve device main body and the cold water inlet of the hot and cold water mixing valve unit are formed on the interior of the valve device main body.

Methods and apparatuses for additively manufactured tubular passages, additively manufactured manifolds, and additively manufactured heaters are provided.

An encapsulated valve system includes a first housing portion having a first facing surface, the first facing surface comprising a plurality of branch pathways formed as a recess within the first facing surface. The valve system further includes a second housing portion having a second facing surface, the second facing surface comprising a plurality of branch pathways formed as a recess within the second facing surface. A disposable conduit is configured to be interposed between the first and second housing portions and disposed within the recess of the first facing surface and the recess of the second facing surface. The disposable conduit is thus sandwiched between the first and second facing surfaces. A plurality of pinch valve actuators are mounted on one or both of the first housing portion and the second housing portion, the plurality of pinch valve actuators configured to pinch the disposable conduit at selective branch pathways.
