Abstract

A pressure balancer system 10 having a pressure balancer 20 and a temperature controller 24 on one side of the system and a volume controller 14 on the other side of the system. The pressure balancer 20 receives hot and cold water which it discharges into the temperature controller 24 at substantially constant preselected pressure. The temperature controller 24 is adjustable to set the temperature of the flow to keep the temperature of the anti-scald below the maximum temperature of between 115° F. and 120° F. The volume controller received the temperature adjusted flow from the temperature controller and will set the volume of the flow at the desired volume for discharge therefrom.

Claims

1. A pressure balancer system comprising:

a. a pressure balancer and temperature controller on one side of the system and a volume controller on the other side of the system;

b. the pressure balancer to receive hot water and cold water supply at varying pressure and to discharge both the hot water and the cold water flows at a substantially constant preselected pressure;

c. the temperature controller connected to receive the flow from the pressure balancer and adapted to keep the temperature of the flow below the maximum anti-scald temperature of between 115°

F. and 120°

F.;

d. the temperature controller to discharge the mixed flow of hot water and cold water at the preselected temperature;

e. the volume controller connected to receive the mixed flow from the temperature controller and to adjust the volume of the flow between a minimum flow and a maximum flow;

f. the temperature controller and the volume controller are interconnected and disposed in spaced relation to each other;

g. the pressure balancer is interconnected to the temperature controller on the upstream side thereof;

h. the temperature controller is disposed on the upstream side of the volume controller;

i. a flow diverter receives the flow from the volume controller and selectively directs it to discharge from a tub spout or a showerhead;

j. a hot water supply line connects into the pressure balancer;

k. a cold water supply line connects into the pressure balancer;

l. a pair of check/stop valves mounted in the supply lines, one in the hot water supply line and one in the cold water supply line;

m. the check/stop valves adapted to be opened or closed to open or close the supply lines to the pressure balancer;

n. the check/stop valve has a bottom member threadedly received into the supply line from the bottom external side thereof; and

o. the check/stop valve connects to the bottom member from the top external side of the supply line to permit the check/stop valve to be disposed immediately adjacent the pressure balancer.

2. A pressure balancer system comprising:

a. a pressure balancer and temperature controller on one side of the system and a volume controller on the other side of the system;

b. the pressure balancer to receive hot water and cold water supply at varying pressure and to discharge both the hot water and the cold water flows at a substantially constant preselected pressure;

c. the temperature controller connected to receive the flow from the pressure balancer and adapted to keep the temperature of the flow below the maximum anti-scald temperature of between 115°

F. and 120°

F.;

d. the temperature controller to discharge the mixed flow of hot water and cold water at the preselected temperature;

e. the volume controller connected to receive the mixed flow from the temperature controller and to adjust the volume of the flow between a minimum flow and a maximum flow;

f. the temperature controller and the volume controller are interconnected and disposed in spaced relation to each other;

g. the pressure balancer is interconnected to the temperature controller on the upstream side thereof;

h. the temperature controller is disposed on the upstream side of the volume controller;

i. a flow diverter receives the flow from the volume controller and selectively directs it to discharge from a tub spout or a showerhead;

j. a hot water supply line connects into the pressure balancer;

k. a cold water supply line connects into the pressure balancer;

l. a pair of check/stop valves mounted in the supply lines, one in the hot water supply line and one in the cold water supply line;

m. the check/stop valves adapted to be opened or closed to open or close the supply lines to the pressure balancer; and

n. the check/stop valve threadedly connected into the flow line from the top external side thereof to open or close the flow therethrough.
