A refrigeration appliance apparatus has an appliance body and an appliance door delimiting a refrigeration chamber. A water-dispensing unit is disposed on a side wall of the appliance body or appliance door. The water-dispensing unit has a guide for dispensing water and at least one actuating unit.

A piston pump for dispensing fluid from a reservoir, an improved vacuum relief arrangement in which a passageway for flow of air from the atmosphere into the reservoir is provided at least in part through a piston-forming element of the piston pump.

System for dispensing a liquid to a user, comprising: a container, a liquid, a dispenser, arranged to receive and hold the container in a dispensing position, and comprising a control unit user, a valve connected to the container, and connected to the control unit to selectively release or stop a flow of the liquid out of the container, characterized in that: upon releasing at least a part of the liquid, the container is deformable, the valve releasing a flow of the liquid out of the container, and upon releasing at least another part of the liquid, the valve releases a flow of liquid out of the container, and allows a flow of gas into the container.

A contactless valve configured to dispense a liquid can include an actuator configured to move a plug between a closed position in which the plug prevents the flow of liquid through valve body, and an open position in which liquid can be dispensed through an outlet. The valve can include an activation sensor, a presence sensor, and a controller configured to control the actuator and in electrical communication with the activation sensor and the presence sensor. The controller can be configured to switch the presence sensor into the activated state in response to the detection of the prerequisite condition by the activation sensor, and to control the actuator to move the plug from the closed position to the open position in response to the detection of the object in the upper detection zone by the presence sensor.
