The invention includes a breather valve used on containers that selectively allows a flow of air through the breather valve and which may be used to regulate the flow rate of fluid from a container or nursing bottle that includes the breather valve. The invention also includes containers and nursing bottles that include the breather valve along with methods of use of the breather valve, the containers and the nursing bottles. The breather valve, the containers, the nursing bottles and the methods of use allow for the ability to adjust flow rate rapidly, provision of a breather valve that may be retrofitted or sold with a new container or nursing bottle. The breather valve is designed in a manner that is semi-permanent to fit.

A multi-way valve, a water softener, and a method for controlling the water softener. The multi-way valve is provided with a main valve and a secondary valve. When each of the main valve and the secondary valve is at a bypass valve position, a water inlet passage, a first main valve passage, a first secondary valve passage, a second secondary valve passage, a second main valve passage, and a water outlet passage of the multi-way valve are sequentially connected, thereby forming a bypass flow path in the multi-way valve.

An overfill prevention valve for use with a tank includes a valve element disposed in a fluid fill path and a float assembly including an actuator and a repositionable float. The float is selectively fixed relative to and moveable relative to the actuator to adjust a target fill level. The float is buoyantly supported by the fluid such that the float and the actuator are shiftable in correspondence with an actual fill level. The actuator is coupled with the valve element such that the valve element shifts to a closed position when the actual fill level nears a target fill level. The float includes discrete buoyant components that are shiftable away from each other and from the actuator to facilitate shifting of the float relative to the actuator and that are securable relative to each other and relative to the actuator to facilitate operation of the float assembly.

Multi-port valve for controlling a medium in a refrigerant circuit of a refrigeration system. A stroke movement of the valve body along an axis is controllable by an actuating element of a drive. The valve body is tubular and extends along the stroke axis and, in a first end position of the stroke movement, passes through at least one first pressure chamber between an inlet and an outlet and at least one further pressure chamber between the inlet and at least one further outlet. At least one seal is associated with each pressure chamber for abutment against the valve body.
