Definitions
- the present invention relates to a device forming a siphon intended in particular to be inserted between two sections of a pipe for discharging waste water.
- siphons having a body comprising an inlet orifice or upstream opening communicating with the upstream section of the pipe and an outlet or downstream orifice communicating with the downstream section of the pipe.
- such a known siphon consists of a hollow body delimiting an ascending tubular part then a descending tubular part joining the outlet orifice. At the junction of the two tubular parts, the body defines an overflow edge located above the inlet.
- the upstream section extends to a level situated above the overflow edge, as is the case with a waste water evacuation pipe, a certain quantity of fluid is retained at the end. flow in the ascending tubular part of the siphon and in the part of the upstream section located below the level of the overflow edge.
- the ascending tubular part of the siphon constitutes means for retaining a fluid plug preventing bad odors appearing in the downstream section from being able to be transmitted into the upstream section. It is obvious that if the fluid plug itself contains smelly elements, bad odors can spread in the upstream section.
- Some devices currently allow only five liters of water to be used, whereas previously seven liters and even eight liters of water were used.
- the usual siphon used with such bowls constitutes a critical point for the reduction in the amount of water necessary for cleaning a toilet bowl.

- the membrane 20 also has a downstream edge 22 (see FIGS. 2 and 5) having the shape of a U situated in a plane perpendicular to the direction of flow and near the outlet orifice 16.
- the distance between the upstream edge and the downstream edge measured along the bottom of the wall 6 in a U, when the membrane is not deformed is shorter than the vertical dimension of the front wall 4 of the body of the device 2, but greater than the diameter of the inlet 12.
- the distance separating the upstream edge from the downstream edge at the edges 20a and 20b may be different from that measured at the bottom of the
- the downstream orifice 16 is situated opposite the interior of the U formed by the membrane 20 when the membrane is in the undeformed state (see FIG. 2).
- upstream inlet orifice 12 is always located inside the U formed by the upstream edge of the membrane 20.
- the body of the device 2 according to the present invention also comprises means for moving the retaining means which consist of means for deformation of the membrane 20.
- the deformation means comprise a rod or pallet 24 situated inside the body between the membrane 20 and the wall 6c forming the bottom of the body.
- the rod 24 is fixed on a shaft 26 extending perpendicular to the direction of flow of the fluid.
- the shaft 26 is rotatably mounted around its axis by means of a bearing (not shown) arranged in a hole (not shown) in the wall 6c and has one end protruding outside the body.
- the shaft 26 may have its other end mounted in another bearing arranged in the hollow body of the device 2.

- the rod 24 In this position of the lever 28, the rod 24 extends perpendicular to the axis of the upstream orifice 12, approximately parallel to the front wall 4 as shown in FIG. 3, and deforms the membrane 20.
- the membrane 20 When the rod 24 is in the latter position, the membrane 20 is deformed so that it has a fold 20c (see FIGS. 3 and 4) extending approximately in a vertical plane passing through the axis of the upstream orifice 12, the fold being slightly inclined relative to the vertical.
- the edge 22 of the membrane extends roughly in a horizontal plane which is located above the inlet orifice because the length of the edges 20a and 20b of the membrane is greater than the diameter of the orifice inlet 12 the edge 22 then constituting an overflow edge.
- the lever 28 When the lever 28 is in the position shown in solid lines in FIG. 6, the rod 24 extends along the bottom of the longitudinal wall 6 in the shape of a U towards the downstream orifice 16 as shown in FIG. 5.
- the length of the rod 24 is smaller than the vertical dimension of the front wall 4 of the body of the device 2.
- the lever 28 When a flow of wastewater is triggered by pouring clean water, the lever 28 is manually actuated in the direction of the arrow in FIG. 6, against the action of the spring 30, and the membrane n is more distorted.
- the actuation of the lever 28 can be roughly simultaneous with the pouring of clean water into the pipeline.
- FIG. 7 Such a toilet bowl 40 fitted with a device 2 according to the invention, is shown in FIG. 7. It includes an inlet 42 for pressurized water opening into the bowl 44 itself and comprising a timed valve 46 provided with 'A push button 48.
- the inlet 42 of pressurized water opens into an O-ring 50 arranged in the upper part of the bowl 44 (see also FIG. 8), the O-ring 50 being pierced with holes 52 regularly spaced at its periphery.
- An annular cover 54 protects and hides the upper part of the O-ring 50.
- a control button 56 is arranged at the rear of the bowl to actuate the timed valve 46.
- control button 56 is integral with a rod 58 slidably mounted in a vertical tubular part 60.
- a horizontal part 62 perpendicular to the rod 58 and integral with the latter protrudes outside the tubular part 60 in passing through a slot (not shown) provided longitudinally in the wall of the tubular part.
- the part 62 extends above the push button 48 of the timed valve 46.
- a spring 64 is arranged between the bottom of the tubular part 60 and the part 62 so as to return the latter to a position remote from the push button 48 as shown in FIG. 7.
- the rod 58 has one end projecting downward from the bottom of the tubular part 60, this end being mechanically connected to the handle 28 so that a downward translation of the rod 58 is transformed into rotation of the lever 28 around the axis of the shaft 26.
- This mechanical connection can be of any type currently known in the movement transformation technique.
- this mechanical connection can be hidden at the level of its mechanical part can be hidden at its lower part by the bowl and its upper part by a box comprising a compartment intended to receive for example paper or cleaning products.
