Definitions

  • the present invention relates to a device for discharging a toilet tank of a place of comfort comprising a vertical cylinder intended to be fixed by its base on a water discharge opening of the wall of tank bottom, a valve seat in the cylinder above this water discharge opening, water intake openings on the periphery of the cylinder above the valve seat, a movable relief valve by vertical sliding in the cylinder above its seat with a hollow valve stem opening under the valve by its lower part and above the cylinder by its upper part, a guide bearing from the valve rod to the upper part of the cylinder and a means of connecting the movable rod-valve assembly to a temporary lifting control.
  • a semi-automatic mechanism is provided so that the actuation of the lifting control of the relief valve releases all of the water contained in the tank, whatever or the brevity of this actuation.
  • This semi-automatic system very simple, is obtained by associating a float to the valve stem, in the cylinder, above and at a sufficient distance from the valve so that its effect is canceled out by the pressure of the filling water on the upper face of the valve, when this water submerges the float in question.
  • a level control float in the usual way, as soon as the emptying is carried out and the valve falls back onto its seat.
  • the object of the invention is to allow effective control of the amount of rinse water used, in accordance with the minimum requirements, using a device of the type described at the start of the description, and this without presenting the risk of overshooting inherent in the aforementioned system of control by a tap.
  • the device according to the invention is characterized in that it includes a pushing means for giving the movable rod-valve assembly a vertical downward pushing capacity greater than the vertical component, directed upwards. , of the pressure of the water contained in the tank on said movable assembly when the valve is lifted from its seat.
  • the amount of rinse water used is thus a function of the actuation time of the valve lift control, which allows the user to easily adjust this amount according to need.
  • the pressure means associated with the movable valve stem assembly can be made in the simplest way by choosing its own weight, in which case the speed of response of the return to the bottom of the valve, when the control is released, is function of the magnitude of the excess weight of this movable assembly relative to the opposite thrust of the water pressure on it; when this excess weight is not considered sufficient, it may be supplemented by adding a ballast to the said assembly.
  • This pressure means can also be supplemented by a compression spring, interposed for example between the valve and the guide bearing of the valve stem.
  • a compression spring interposed for example between the valve and the guide bearing of the valve stem.
  • Figure 1 of this drawing is an overall view in axial half-section of the first embodiment.
  • Figure 2 is a partial view in axial half-section of the second embodiment.
  • the device according to these two embodiments is shown in these two figures in the lowered closed position of the relief valve.
  • this device consists of a vertical cylinder 1 fixed by its base on a water discharge opening from the bottom wall 2 of a flush tank, a relief valve 3 with its rod 4, a compression coil spring 5, a cylinder cover 6 and a bearing 7 for guiding the valve rod 4.
  • the distance C between the stop 27 and the counter stop 26 defines the height stroke of the movable rod 4-valve assembly 3.
  • This stroke is here, in its maximum value represented in this figure, provided so that when the valve 3 is fully raised, abutment against abutment, the openings 13 for admitting water into the cylinder 1 are completely cleared over their entire height, the flow rate of the rinsing water discharged then being at its maximum value.
  • the pressure of the compression spring 5, in the position shown for maximum extension, is provided such that, by summation of the dead weight of the movable rod 4-valve assembly 3, it gives this assembly a thrust capacity towards the bottom greater than the vertical component, directed upwards, of the pressure of the water in the reservoir on said assembly when the valve is lifted from its seat.
  • the free length D of screwing the bearing 7 into the cover 6 of the cylinder, before the latter meets the handwheel 24, is provided, in the position of maximum travel C shown, less than this travel C, so that 'There is always a minimum of height cleared from the water intake openings 13 in the cylinder at the end of the screwing of the bearing 7 by the handwheel 24 when the valve 3 is fully raised.
  • a non-adjustable system, in which the spring 5 is directly supported under and against the cover 7 is perfectly acceptable in a simplified and economical design.
  • the openings 14 in the upper part of the cylinder 1 are not essential when, for example at the end of the valve lift stroke 3, there remains still above its level a part which is clear of the water intake openings 13 , or when the outside diameter of the valve is sufficiently smaller than the inside diameter of cylinder 1.
  • valve lifting control which goes beyond the scope of the invention, can be of any other type, such as for example a lateral lever control or a pneumatic or hydraulic foot control.
  • a spring which is advantageous when using low density material for the production of the device, such as certain materials moldable plastics, may not be necessary and replaced by the self-weight of the movable stem-valve assembly when the sole self-weight of this assembly exceeds by sufficient quantity the opposite thrust of the water to ensure an acceptable response speed from the downward return of the valve, to the release of the valve lift control.
  • a metal ballast 29 in the form of a ring of rectangular cross section included in a housing in two similar parts 30 of cylindrical shape each surmounted by a sleeve 31, the whole being threaded around the stem valve and fixed thereon, for example by gluing, at a level defined by the stroke C chosen, assembly of the assembly.
  • the cover 70 of the cylinder 1 has here a simple central hole 32 forming a guide bearing for the valve stem 4, and its inner wall 33 constitutes the stop for limiting the upward movement of the valve.
  • This cover 70 is here represented removable by the by means of a quick bayonet fastening system 34 which can be engaged in L-shaped grooves 35 for retaining the wall of the cylinder 1.
  • Openings 36 in the wall of the upper part of the cylinder 1 and holes 37 in the cover 70 are provided to facilitate the evacuation / admission of water into this upper part during movement of the movable rod assembly. valve.
  • the metallic ballast included in the housing can be replaced by other materials, for example lead shot, coated or not with plastic material of the kind of cold-polymerizable resins such as polyester or epoxy.
  • valve stem 4 may have level marks.
