Abstract

A system is disclosed for controlling the flow of a liquid from a liquid pressure line for flushing a toilet bowl comprising a valve interconnecting the liquid pressure line and the toilet bowl. An electrical control generates a first and a second timer period with the second timer period being longer in duration than the first timer period. The electrical control is connected to the valve for opening the valve for the first timer period for flushing a liquid waste from the toilet bowl and for opening the valve for the second timer period for flushing a solid waste from the toilet bowl.

Claims

1. A system for controlling the flow of a liquid from a liquid pressure line for flushing a toilet bowl of a toilet, comprising in combination:

valve means interconnecting the liquid pressure line and the toilet bowl of the toilet;

said valve means comprising a reciprocal valve disposed within an internal cavity of said valve means;

said reciprocal valve being movable between a closed position for inhibiting the flow of the liquid under pressure from the liquid pressure line into the bowl of the toilet and an open position for permitting the flow of the liquid under pressure from the liquid pressure line into the bowl of the toilet;

switch means having a first activation state and a second activation state;

electrical control means having timer means for generating a first timer period and a second timer period;

said second timer period of said timer means being longer in duration than said first timer period of said timer means;

means connecting said switch means to said electrical control means for activating said timer means for said first time period upon said switch means being in said first activation state and for activating said timer means for said second timer period upon said switch means being in said second activation state;

connector means for connecting said electrical control means to said valve means for moving said valve means into said open position for said first timer period upon said switch means being in said first activation state for flushing a liquid waste from the toilet bowl of the toilet with a first volume of water and for moving said valve means into said open position for said second timer period upon said switch means being in said second activation state for flushing a solid waste from the toilet bowl of the toilet with a second volume of water; and

motive means for moving said reciprocal valve between said closed position and said open position including fluid operated motive means.

2. A system for controlling the flushing a toilet bowl of a toilet as set forth in claim 1, wherein said electrical control means is programmable for varying said first timer period in said electrical control means for varying the duration of flushing liquid waste in the toilet bowl and for varying said second timer period in said electrical control means for varying duration of flushing of the solid waste in the toilet bowl.

3. A system for controlling the flushing a toilet bowl of a toilet as set forth in claim 1, including a display and control panel located proximate the toilet for housing said switch means.

4. A system for controlling the flushing a toilet bowl of a toilet as set forth in claim 1, wherein said valve means comprises means for regulating the flow rate of the liquid directed to the toilet bowl of the toilet;

and

said electrical control means enabling the operator to select said first position of said switch means to activate said electrical control means for flushing a liquid waste from the toilet bowl of the toilet with a first flow rate of water and for enabling the operator to select said second position of said switch means to activate said electrical control means for flushing a solid waste from the toilet bowl of the toilet with a second flow rate of water.

5. A system for controlling the flushing a toilet bowl of a toilet as set forth in claim 1, wherein said valve means comprises means for regulating the flow rate of the liquid directed to the toilet bowl of the toilet.

6. A system for controlling the flushing a toilet bowl of a toilet as set forth in claim 1, wherein said motive means includes hydraulic motive means.
