An electrical beverage brewer (10) having a controller (26) responsive to a start switch (72) to operate a brew cycle by dispensing hot water from a tank (42) to beverage ingredient within a brew basket (38) through a bent tube (78) mounted to the water tank (42) for rotation about an axis aligned with an external horizontal rotary section (90) of the bent tube (78) between a closed position in which an inlet (80) of a swinging tubular section (79) is in a relatively elevated, closed position and an open position at a lower elevation relative to the closed position. A rotary electromechanical solenoid (96), a pneumatic rotary solenoid (134) or a stepper motor (126) or other like rotary, drive mechanism requiring no positional sensors has a rotary axis aligned with the central axis of rotation of the rotary section (90) and axially linked, inline, with the rotary section (90) to axially drive the rotary section (90) and thereby move the swinging section (79) between the open position and the closed position without applying lateral forces to the rotary section (90).

The electrical beverage brewer of claim 10 in which the non-straight angle is approximately ninety degrees. 12. The electrical beverage brewer of claim 1 in which the inline, rotary drive mechanism is energized by the controller in response to manual actuation of the start switch to move the swinging section to the open position. 13. For use in an electrical beverage brewer having, a start brew switch, a controller responsive to the start switch to operate a brew cycle, a water tank and a brew basket for holding beverage ingredient, the improvement being a water dispense system for selectively passing water from the water tank to the brew basket, a method of brewing comprising the steps of: mounting a generally bent dispense tube to a water tank for rotation between a closed position in which an inlet of the tube is in a relatively elevated, close position, and an open position at a lower elevation relative to the closed position, said tubular body being mounted with the swinging section and inlet located within the water tank and at least part of the rotary section defining an exterior rotating section located without the water tank with the outlet in fluid communication with the brew basket to pass water to the brew basket;rotating the exterior rotating section with a powered inline, rotary, drive mechanism with a rotary axis aligned with a central axis of rotation of the rotary section and axially linked, inline, with the rotary section to axially drive the rotary section and thereby move the swinging section between the open position and the closed position without applying lateral forces to the rotary section;holding the rotary section stationary with the swinging section in the open position to pass a preselected amount of water to the brew basket through the bent dispense tube from the water tank to the brew basket; andafter the preselected quantity of water has been passed to the brew basket, rotating the exterior rotary section with the powered, inline, rotary, drive mechanism to axially drive the rotary section and thereby move the swinging section from the open position to the close position without the application of lateral forces to the rotary section. 14.
