Abstract
A bathroom flusher includes a body having an inlet in communication with a supply line and an outlet 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 at a valve seat thereby controlling flow from the inlet to the outlet, and an actuator 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 controller may execute a novel control algorithm.
Claims24
1-16. (canceled)
A bathroom flusher comprising:
- a body having an inlet and an outlet,
- a valve assembly in said body positioned to close water flow between said inlet and outlet upon sealing action of a moving member at a valve seat thereby controlling flow from said inlet to said outlet, and
- an actuator for actuating operation of said moving member.
21-27. (canceled)
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
- a control circuit, including a light detector for detecting presence of an object.
29-32. (canceled)
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.
