1. A toilet assembly comprising:

  • a bowl;

    a toilet seat member mounted on the bowl for movement between raised and lowered positions;

    a tank mounted on the bowl, the tank adapted to contain water for flushing the toilet and having a flushing apparatus for causing the water in the tank to flow into the bowl;

    a hydraulic closure apparatus mounted on the toilet, the apparatus including a member movable relative to the toilet and engageable with the seat member such that movement of the member in one direction moves the seat member toward the lowered position, and such that movement of the seat member toward the raised position moves the member in an opposite direction;

    a cylinder;

    a piston slidable inside the cylinder, the piston dividing the cylinder into first and second chambers, and the piston connected to the member such that movement of the member in the opposite direction moves the piston in the direction minimizing the volume of the second chamber;

    a spring positioned in the second chamber, the spring being compressed by the piston when the piston moves in the direction minimizing the volume of the second chamber; and

    a conduit having one end communicating with the second chamber and having a second end positioned in the water in the tank; and

    a valve arrangement for closing the second end of the conduit when the tank is relatively full of water and for opening the second end of the conduit when the toilet is flushed.
