Abstract: A liquid dispensing device includes at least one piston pump (7), which sucks liquid to be dispensed from a container in a filling cycle and applies the liquid to a target in an emptying cycle and which is driven by an actuator comprising an actuating element (1) that is arranged to move a piston rod (2) between two extreme positions, and a gripper (3) attached to the actuating means (1), which gripper is able to engage with the piston rod (2) so as to move it along with the actuating element. The gripper (3) is made able to engage with the piston rod (2) only in its first extreme position and arranged to disengage automatically from the piston rod in its second extreme position.

Abstract: An apparatus for preventing the drying of at least one nozzle of a fluid dispensing device includes an element providing moist gas, a supply hose for moist gas and a gas controller which forms a space around the nozzle. Moist gas is led into the space around the nozzle from the elements providing gas through the supply hose. Moist gas leaking out of the space is replaced by new moist gas led into the space.
