Abstract

FIELD: sanitary engineering; water-closet mounted flushing cisterns with central opening in lid. SUBSTANCE: flushing cistern has lid with central opening, lever, spring, filler fittings, and outlet fittings. The latter has telescopic rod of outlet valve and its bar and tube members and ensures variable outlet water flow. Self-contained outlet fittings have button installed in central bore of full-drain actuator and provided with reset spring and rod with pusher engaged with five-link hinge-and-lever assembly of pair of first- class levers, balancer with vertical slits at ends, and coupling-links provided with compression springs; coupling-links are joined with balancer for longitudinal displacement in its slits. Supports are arranged at levers on guide which is essentially bracing tube of flushing cistern lid provided with longitudinal slits diametrically arranged in same plane just like tubular member of outlet telescopic rod placed in this tube; slits are designed to receive adjacent lever arms and balancer which are free to move along them and also to allow for displacement of tubular member of telescopic rod relative to levers and balancer in the course of full water outlet from flushing cistern. Bar member of telescopic rod has additional stop at its end for engaging the balancer. EFFECT: reduced consumption of tap water. 3 cl, 5 dwg

Description

 The invention relates to sanitary equipment, namely to flushing cisterns with a central hole in the lid, mounted directly in the toilets.

 Known flush tank with automatic shutdown of partial dosed water discharge according to USSR author's certificate N 1502732, E 03 D 1/14, 08/23/1989, containing a cover with a central hole, a lever, a spring, filling fittings and exhaust fittings, including a telescopic rod of the exhaust valve and its rod and tubular elements, providing a variable flow of water.

 The aim of the invention is to save tap water consumed by flushing tanks.

 The problem is solved in that in a flushing tank with automatic shutdown of a partial metered water drain containing a cover with a central hole, a lever, a spring, filling fittings and exhaust fittings, including a telescopic stem of the exhaust valve and its rod and tubular elements, providing variable water flow, the exhaust the valve is autonomous and contains a button with a return spring and a rod with a pusher interacting with azhno-pyatizvennikom hinge consisting of a pair of one-kind levers, equalizer configured with vertically spaced recesses at the ends, and equipped with compression springs connecting links fastened together with a leveler to move longitudinally in its slots.

 In addition, at the levers, the supports are placed on the guide - the coupling tube of the tank cover fastening, which, like the tubular element of the telescopic valve of the exhaust valve located in it, is made with longitudinal slots diametrically located in the same plane with the possibility of placing and moving adjacent arms of the levers in them and leveler, as well as with the possibility of moving the tubular element of the telescopic rod relative to the levers and the leveler during the complete discharge of water from the tank.

 In addition, the bar element of the telescopic rod is equipped with an additional stop at the end for the possibility of interaction with the equalizer.

 In FIG. 1 shows a General view of the exhaust valves, in FIG. 2 - the position of the elements of the outlet valves of the partial dosed discharge of water at the time of maximum opening of the outlet valve, in FIG. 3 - the same at the moment of completion of the partial discharge, in FIG. 4 - the same at the moment of returning to the starting position with the button released, in FIG. 5 - the position of the elements of both valves with the complete discharge of water from the tank.

 A flushing tank with automatic shutdown of a partial metered water discharge contains a handle 1, a special nut 2, a cover 3, a guide — a coupling tube for fastening the tank cover 4 and a tubular element 5 of the telescopic rod of the exhaust valve, made with longitudinal diametrically arranged slots; rod element 6 of the telescopic rod, made elongated with supports 7 and 8, exhaust valve 9, bracket 10, button 11, made in order to simplify installation in the handle in the form of a cap with longitudinal slots and with a flange on the side of the open part; a return spring 12, a stem 13 with a cylindrical pusher 14; levers of the first kind 15, having at the ends of adjacent shoulders a vertical recess 16 for placing the rod 13 when it is in the lower position; connecting links 17 with stops 18, compression springs 19 and nuts 20, equalizer 21, latches 22, restricting the movement of the equalizer in the horizontal plane.

 A flushing tank with automatic shutdown of a partial metered discharge of water operates as follows. When the button 11 is pressed, the pusher 14 connected to it by means of the rod 13 lowers the adjacent arms of the levers 15, while the external arms, rising, carry the connecting links 17, the equalizer 21 and the rod element of the rod 6 with the exhaust valve 9. The process of draining the water continues to closing the outlet with the valve under the influence of its gravity and suction force, after the pusher 14, when the button 11 is pressed all the way down, falls over the ends of the lever arms and the rod 13 is located in the recesses 16. At the same time, since the pusher is no longer in operation so the levers, all links lever-hinge mechanism, mainly the force suction valve, returned to the original position, and along with it the rod with the pusher 14, which raised the adjacent lever arm, takes a position on them. In this case, the outer shoulders of the levers and the connecting links 17 will fall, moving in the slots of the equalizer, but under the action of the springs 19, based on the equalizer, will also return to their original position. Thus, the outlet valve is ready for action again. The dosage of partial drainage of water, required by operating conditions, is carried out by the manufacturer by changing the duration of the drainage cycle by selecting the optimal parameters of the pusher 14 and the arms of the levers 15. A complete drainage of water from the tank occurs when the handle 1 is lifted to the stop with the telescopic rod connected to it.
