A dispenser apparatus for ultrasound gel comprises a cylindrical body having a closed first end and a dispensing opening at the other end. There is an inlet opening near the first end in fluid communication with a source of pressurized ultrasound gel. A plunger is secured to a shaft near its first end; and there is a valve element at the second end of the shaft, adapted to close the dispensing opening when the shaft is in a first, at rest position, and to permit a dispensing operation when the shaft is in a second, dispensing position. The plunger has at least one passageway formed through its thickness, extending towards a second face. A plunger return spring acts against the second face of the plunger, so as to urge it towards the rest position. A freely moving sealing plate covers the passageway, and is mounted for longitudinal movement along the shaft; and has a return spring to urge it towards the second face of the plunger. The plunger covers the inlet opening when in its first position. A trigger moves the shaft and the plunger against the return springs, and the valve element is moved into the dispensing position away from the dispensing opening. Chambers above and below the plunger are always filled with gel.
