A coffee brewer with means for dispensing controlled quantities of hot water comprising well known coffee brewing means including a main water tank having a heater therein, means for introducing water to the tank and a discharge conduit for passing coffee brewing water from the tank wherein there is provided a separate and preferably removable, closed water bottle mounted for gravity feed of water to the tank, a discharge conduit connecting the bottle to the tank, the normal operational position of the end of which proximal to the tank being located such that water normally covers it before water in the tank reaches a level sufficient to pass through the conduit for discharging brewing water, a separate, valve controlled single-cup water discharge spigot connected to the tank beneath the level in the tank of the end of the conduit connecting the bottle with the tank, a valve normally blocking the gravitational discharge of water from the bottle and valve actuating means which open the valve when the bottle is mounted in its normal operational position for gravity feed of water to the tank.

A coffee brewer with means for dispensing controlled quantities of hot water comprising a water tank, means for heating the water in the tank, water inlet means connected to the tank, a water discharge siphon connected at one end to the tank, the opposite end of the siphon being at a level beneath the first said end thereof, a water reservoir, a supply conduit connecting the reservoir to the water tank, the end of the supply conduit in the tank being positioned beneath the level of the end of the siphon in the tank, the said reservoir being closed except for said supply conduit and being positioned for gravity discharge into said water tank, a water discharge conduit connected at one end to the tank beneath the level of the end of said supply conduit therein, and valve means in the said discharge conduit.

A metering valve, preferably electromagnetically actuatable, for the successive delivery of precisely measured volumes of fluid irrespective of inlet fluid pressure, including a valve core, slidably mounted in a cavity in the valve body, the top of the core closing a normally open fluid inlet when the core is moved to an uppermost position, and the bottom of the core closing a fluid discharge outlet when in its normal lowermost position, the volume of fluid discharged being the volumetric difference between the volume of the cavity and the volumetric displacement of the core.
