Abstract: A toilet flush opening device (10) includes a water cistern (12) that includes a lower discharge aperture (14) and a vertical moveable discharging open/close element (16) for this aperture (14), which is able to occupy a closed lower position to keep the water in the cistern (12) or an open upper position to discharge the water into a toilet bowl. The device is characterized in that the open/close element (16) can be urged from its lower position to its upper position by an electrohydraulic actuator (18) which includes a controlled solenoid valve (20), and an expandable hydraulic device (22) that can be supplied with water at pressure by the solenoid valve (20) to urge the open/close element (16) from its closed lower position to its open upper position.

Abstract: The present invention relates to a suite of configurable products which can be configured during fitting. It also relates to a configuration tool tailored to this suite of configurable products. It relates finally to a configuration process for such products. A configuration tool (19) linked by an infrared channel (18) for communicating configuration words initially recorded in a memory (34), and selected by a keypad (23) performs the loading of the configuration words into the memory (6) of a control circuit (1) equipped with a microcontroller (2) executing a program for configuring a configurable product, such as a sanitary ware during the on-site fitting thereof. Application to a suite of sanitary ware products.
