Abstract
A dispensing device for a liquid, including a reservoir inside which a holding chamber for a liquid is defined; a ram movable inside the holding chamber, wherein between the ram and the seat a variable volume working chamber is defined, able to communicate with the holding chamber; and a non-return valve, arranged at the outlet opening and downstream of the seat. During the stroke of the ram from a forward end-of-stroke position to a backward end-of-stroke position the liquid flows from the holding chamber to the working chamber, and during the stroke of the ram from the backward end-of-stroke position to the forward end-of-stroke position the liquid is dispensed out from the working chamber through an outlet opening. The device further includes an actuating group arranged outside of the holding chamber and capable of contactlessly controlling motion of the ram.
