| description | A liquid dispensing device is disclosed comprising a dispensing head, which in turn comprises an inlet valve, a piston (3) and a piston chamber, and an actuator for controlling the piston (3). The dispensing head further comprises a buffer (6) in fluid communication with the piston chamber, an outlet valve having a defined minimum opening pressure in fluid communication with one of (i) the buffer and (ii) the buffer and the piston chamber, and a nozzle (9) with a defined throughput in fluid communication with the outlet valve. The buffer is a gas buffer (6) comprising a gas-filled buffer bag made from a flexible material and arranged in a buffer housing. |
