Claim 10

A temperature/volume control system for use with a standard water distribution system having hot and cold water supply valves and valve stems comprising: input means for allowing a user to set a desired temperature and/or pressure of water supplied by the distribution system; a base plate having at least one aperture whereby the hot and cold water supply valve stems are accessible through the aperture of the base plate when the base plate is surface mounted on the wall so that the plane of the base plate is substantially perpendicular to the hot and cold water supply valve stems; first and second gears operatively connected to the respective hot and cold water supply valve stems such that each gear is lies in a plane substantially parallel to the plane of the base plate; a first pair of rod and pawl assemblies for co-acting with the first gear, the assemblies located on opposite sides of the first gear, whereby movement of one rod and pawl assembly causes the first gear to rotate in one direction to open the valve and movement of the other rod and pawl assembly causes the gear to rotate in the opposite direction to close the valve; a second pair of rod and pawl assemblies for co-acting with the second gear, the assemblies located on opposite sides of the second gear, whereby movement of one rod and pawl assembly causes the second gear to rotate in one direction to open the valve and movement of the other rod and pawl assembly causes the second gear to rotate in the opposite direction to close the valve; two pairs of solenoids, each solenoid operatively connected to one of the rod and pawl assemblies whereby a predetermined rod and pawl assembly may be operated to open or close a respective valve in order to control pressure and/or temperature, and control means responsive to the input means for controlling the solenoids in order to deliver a predetermined temperature and volume of water in accordance with the operator input.

Claim 11

A temperature/volume control system for use with a standard water distribution system having hot and cold water supply valves and valve stems comprising: input means for allowing a user to set a desired temperature and/or pressure of water supplied by the distribution system; a base plate having at least one aperture whereby the hot and cold water supply valve stems are accessible through the aperture of the base plate when the base plate is surface mounted on the wall so that the plane of the base plate is substantially perpendicular to the hot and cold water supply valve stems; first and second gears operatively connected to the respective hot and cold water supply valve stems such that each gear is lies in a plane substantially parallel to the plane of the base plate; a first pair of rod and pawl assemblies for co-acting with the first gear, the assemblies located on opposite sides of the first gear, whereby movement of one rod and pawl assembly causes the first gear to rotate in one direction to open the valve and movement of the other rod and pawl assembly causes the gear to rotate in the opposite direction to close the valve; a second pair of rod and pawl assemblies for co-acting with the second gear, the assemblies located on opposite sides of the second gear, whereby movement of one rod and pawl assembly causes the second gear to rotate in one direction to open the valve and movement of the other rod and pawl assembly causes the second gear to rotate in the opposite direction to close the valve; two pairs of solenoids, each solenoid operatively connected to one of the rod and pawl assemblies whereby a predetermined rod and pawl assembly may be operated to open or close a respective valve in order to control pressure and/or temperature, and control means responsive to the input means for controlling the solenoids in order to deliver a predetermined temperature and volume of water in accordance with the operator input.
