A bathroom flusher includes a flusher body, a valve assembly, an electronic control system, and a flusher cover. The flusher body includes an inlet and an outlet, and is designed to accommodate the valve assembly that controls water flow between the inlet and the outlet. The valve assembly includes a valve member movable with respect to a valve seat providing a sealing action based on applied pressure on the valve assembly. The bathroom flusher also includes an external cover designed for enclosing an electronic control module comprising a battery, a sensor, and an actuator for controlling operation of the flush valve, wherein the external cover includes at least two cover parts separately removable, and wherein the external cover is attachable with respect to the valve body in a manner also allowing removable attachment of the control module.

The flush valve of claim 5 wherein said top cover includes at least one side surface designed for facilitating removal of said top cover. 11. The flush valve of claim 5 wherein said top cover is attached with respect to said valve body using at least one screw. 12. The flush valve of claim 5 further including a removable element designed for shipping and storage, said removable element being positioned to retain said button in said lower position when assembling said top cover. 13. The flush valve of claim 1 or 2 wherein said valve member includes a piston. 14. The flush valve of claim 1 or 2 wherein said valve member includes a flexible diaphragm. 15. The flush valve of claim 14 wherein said flexible diaphragm includes a centrally located passage connecting a relief passage and said outlet, said flexible diaphragm being retained with respect to said valve body by a pilot cap defining said pilot chamber. 16. The flush valve of claim 15 including a bypass orifice in said diaphragm connecting said inlet with a pressure chamber inside said pressure cap, said orifice having a cross section area smaller than that of said passage. 17. An automatic toilet room flush valve comprising: a valve body including an inlet and an outlet and a valve seat inside said body; a valve member cooperatively arranged with said valve seat, said valve member being constructed and arranged to control water flow between said inlet and said outlet, movement of said valve member between open and closed positions being controlled by water pressure inside a pilot chamber; and an external cover designed for enclosing an electronic control module comprising a battery, and a sensor and for enclosing an actuator for controlling operation of said flush valve, said external cover including at least a main cover body, a front cover and a top cover removable with respect to said main cover body, said external cover being attachable with respect to said valve body in a manner also attaching said control module, wherein both said main cover body and said top cover of said external cover are removable to enable separate servicing and replacement of said control module while maintaining said water pressure in said pilot chamber, wherein said main cover body, said front cover, and said top cover are constructed to include attachment surfaces included on said main cover body and said front cover enabling attachment by at least one screw to a pilot cap defining said pilot chamber and being attached to said valve body. 18.
