Abstract
A bathroom flusher (10) includes a body having an inlet (12) in communication with a supply line and an outlet (16) in communication with a flush conduit, a valve assembly in the body positioned to close water flow between the inlet and the outlet upon sealing action of a moving member (60, 60A, 60B, 60C, 130, 210, 215, 526, or 628) at a valve seat (70, 70A, 140, 209, 251A, 526 or 625) thereby controlling flow from the inlet to the outlet, and an actuator (62) for actuating operation of the moving member. The bathroom flusher includes one of several novel sensors and is controlled by one of several novel controllers, as described. The controllers may execute a novel control algorithm.

28. An automatic flow-control system comprising:
-
an electric valve operable by application of control signals thereto between an open position, in which it permits fluid flow therethrough, and a closed position, in which it prevents fluid flow therethrough; and

33. An electromagnetic actuator system, comprising:
-
an actuator including a solenoid coil and an armature housing constructed and arranged to receive in a movable relationship an armature;
a controller coupled to a power driver constructed to provide a drive signal to said solenoid coil for displacing said armature and thereby open or close a valve passage for fluid flow; and
an actuator sensor constructed and arranged to sense a position of said armature and provide a signal to said controller. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)
