Abstract
A drain valve activator assembly for a container such as a bathtub is disclosed. In one embodiment, there is an overflow plate mountable on a side wall of the tub at the overflow outlet. A stem is positioned through the plate so as to rotate on its own longitudinal axis, so as to have one end extending into the bathtub, and so as to have one end extending out of the bathtub. A solenoid is provided outside the tub with a holding member such as a leaf spring. Upon activation, the solenoid pulls the leaf spring away from the stem. Normally, the leaf spring is biased towards the stem. The holding member and a stem end are configured so as to be able to interfit and inhibit stem rotation when the leaf spring abuts against the stem. A torsion spring stores the rotational energy used to manually open the valve, and then uses that energy to drive the valve to the closed position in response to the solenoid operation.
