Definitions
- the present invention relates to a device, in particular a pneumatic device, for controlling a flush tank drain valve.
- a flush tank drain valve comprises a movable member fitted with a shutter which cooperates with a fluidtight seat; and, to drain the water from the tank, the movable member is raised by means of a pneumatic system connected to a user-operated pneumatic control device.
- the pneumatic control device In the case of walled-in or recessed tanks, the pneumatic control device generally comprises a supporting structure fixed to the wall and having a button for operating a lever mechanism which cooperates with a piston sliding inside a chamber to produce an air pulse; and the air pulse is fed to the pneumatic system which raises the shutter to drain the water from the tank.

Description
- The present invention relates to a device, in particular a pneumatic device, for controlling a flush tank drain valve.
- Generally speaking, a flush tank drain valve comprises a movable member fitted with a shutter which cooperates with a fluidtight seat; and, to drain the water from the tank, the movable member is raised by means of a pneumatic system connected to a user-operated pneumatic control device.
- In the case of walled-in or recessed tanks, the pneumatic control device generally comprises a supporting structure fixed to the wall and having a button for operating a lever mechanism which cooperates with a piston sliding inside a chamber to produce an air pulse; and the air pulse is fed to the pneumatic system which raises the shutter to drain the water from the tank.
- In known control devices, the mechanism connecting the button to the piston comprises numerous interconnected component parts, and is therefore relatively complex and expensive to produce and assemble. Moreover, the presence of lever mechanisms may impair operation and/or reliability of the device as a whole.
- It is an object of the present invention to provide a flush tank drain valve control device which is extremely straightforward to produce and assemble, while at the same time providing for maximum efficiency and reliability.
- According to the present invention, there is provided a device for controlling the drain valve of a flush tank, and comprising a supporting structure fitted with at least one button cooperating with an actuator of a pneumatic assembly to generate an air pulse; the device being characterized in that said button is a rocking button which cooperates with and exerts thrust directly on said actuator.
- The control device according to the invention is therefore extremely straightforward and cheap and easy to produce and assemble, while at the same time providing for maximum efficiency and reliability.
- An important aspect of the invention is that the supporting structure comprises a frame supporting the pneumatic assembly; and a plate fixable removably to the frame and supporting the button. And the frame is designed to selectively support one or more pneumatic assemblies.
- Control devices can thus be produced cheaply and easily for both single-drain valves (i.e. permitting full drainage of the tank only) and dual-function drain valves (i.e. selectively enabling full or partial drainage of the tank) by simply changing a small number of component parts of the control device to switch from one version to the other.
- Known solutions, on the other hand require a specially designed control device for each application (single-drain or dual-function drain valves), or at least comprise numerous component parts specially designed for one version or the other, with only a very few parts being common to both.
- A number of non-limiting embodiments of the present invention will be described by way of example with reference to the accompanying drawings, in which:
- Figure 1 shows a schematic exploded view in perspective of a first embodiment of a flush tank drain valve control device in accordance with the invention;
- Figure 2 shows a lateral section, with parts removed for clarity, of the Figure 1 device assembled;
- Figure 3 shows a view in perspective of a first component part of the Figure 1 device;
- Figure 4 shows a view in perspective of a second component part of the Figure 1 device;
- Figure 5 shows a schematic exploded view in perspective of a second embodiment of the invention.
