ABSTRACT:
A water valve structure for disposition between the supply pipe and shower head of a bathroom shower. The valve structure includes an actuator shiftable between "on" and "off" positions and spring biased toward the "off" position. An actuator latch under the control of a water flow driven motor is also provided and an operator is provided for initiating movement of the actuator from the "off" position to the "on" position and for also winding a spring drive mechanism controlling a second latch operable to latch the actuator in the "off" position. Actuation of the operator winds the spring drive mechanism and retracts the second latch to allow spring biased movement of the valve structure actuator to the "on" position thereof in which it is latched by the first latch. The flow of water through the water valve structure actuates the motor and the motor, after a predetermined time interval, deactuates the first latch allowing movement of the valve structure actuator, by spring pressure, toward the "off" position in which it is latched by the second latch. Thereafter, the spring drive mechanism is automatically actuated and after a predetermined time interval, the second latch is rendered inoperative after which the water valve structure may again be shifted to the "on" position thus beginning the second cycle of operation of the water valve for a predetermined time interval for rinsing operations.
