ABSTRACT:
An aquarium includes a pump disposed in a chamber of a container to circulate water and having a spindle. An air supplying device is coupled to the spindle of the pump and driven by the spindle of the pump, to pump air into the water contained in the chamber of the container. The pump may thus be used to pump or circulate the water in the aquarium, and to simultaneously supply air into the water contained in the aquarium. The air supplying device includes a valve housing having two check valve members disposed in a recess and a depression, and a membrane attached to the valve housing and forced by the pump to actuate the check valve members.
