The present application discloses liquid dispensers, refill units for liquid dispensers, liquid pumps, lost motion devices, and methods for installing a refill unit and lost motion device. In certain embodiments, a liquid dispenser of the present application comprises a container for holding a liquid, a pump housing connected to the container, a liquid or air chamber, and a piston movable in the liquid or air chamber. A connector is linked to the piston. The connector has a flexible portion for connecting to the piston and an attachment portion for attaching to an actuator of the dispenser. A restrictor is positioned between the flexible portion of the connector and the piston. Movement of the connector a first distance in a first direction results in lost motion between the actuator and the piston and continued movement of the connector a second distance in the first direction moves the piston with the actuator. |
