Definitions

• Flushing device with a pressurized chamber, drain fitting for a flushing device and system with a flushing device and a toilet bowl
• the invention relates to a flushing device according to the preamble of claim 1.
• Flushing devices of the type mentioned have long been known and are also referred to as pressure cisterns.
• the water present in the rinsing tank is at rest under the pressure of a pressure space above the water.
• the pressure chamber contains air that cannot leave the container and has an overpressure. The overpressure is generated when the cistern is refilled.
• the closure body of the drain fitting is raised and the flushing water present in the container is released into a toilet bowl while the air in the pressure chamber is released.
• the rinsing water therefore leaves the container not only because of its own weight, but also under the effect of the pressure chamber.
• the pressure in the tank causes the rinsing water to be dispensed at a higher speed during a rinse.
• An example of such a flushing device has become known from US Pat. No. 6,343,387 B1.
• the advantage of such flushing devices is in particular that they can be flushed with comparatively little water or high energy.
• the invention has for its object to provide a flushing device of the type mentioned, which enables even further savings in flushing water.
• the object is achieved in a generic flushing device according to claim 1.
• the rinsing device has means for rinsing with a subset of the rinsing water.
• the flushing process can be interrupted or two flushing quantities are available in different chambers. This makes it possible to carry out either a full or partial flush. It is therefore not necessary in all cases to rinse with the entire amount of rinsing water present in the container. It can also be rinsed with a portion of the water present, where such a portion is sufficient for rinsing. In practice, this is possible in many cases, so that a great deal of water and in particular fresh water can be saved with the flushing device according to the invention, which is a considerable advance from an economic and ecological point of view.
• the interruption of the flushing can be set as desired or also permanently. With a fixed setting, the flushing quantity is determined for a partial quantity and is, for example, 3 1.
• the triggering can be mechanical or non-contact.
• the flushing device is also particularly suitable for an automatic toilet system in which, for example, sensors automatically trigger a full or partial flush.
• Means have a force-loaded part, which moves the valve body down onto the valve seat when the purging is interrupted. This enables with comparatively simple Means a quick interruption during different flushing phases.
• the force-loaded part is displaceably mounted in the drain fitting.
• This enables a particularly compact design and has the particular advantage that the installation of the flushing device is no more complex than before.
• the part is permanently integrated in the drain fitting and is installed without any further assembly steps when installing this fitting.
• the force-loaded part is spring-loaded.
• This part is held, for example, with a locking device in the tensioned state. After the locking device has been released, the part acts on the closure body under the force of the spring and forces it into the closed position.
• the force-loaded part is mounted in the piston mentioned.
• the force-loaded part is brought into a starting position or rest position, for example a compression spring being tensioned.
• the compression spring can be replaced by another force, for example a weight or a magnet.

Since the vent valve 11 is now closed, the air in the pressure chamber 15 cannot escape and is compressed by the rising water. If the water surface 42 is at the level shown in FIG. 1, the pressure in the rinse water 14 is so great that the vent valve 19 closes. The supply of water into the container 2 is thus ended.
