<p>The unit has a nozzle (34) with a spray hole and a fluid circulation channel between the hole and a supply opening, where the unit is formed of a single piece of plastic material. A push rod (30) has a cavity to accommodate a pump rod, and a channel connecting the cavity to the opening. A flexible connection unit (38) is connected to the push rod and the nozzle. The flexibility of the unit (38) allows a relative displacement of the push rod and the nozzle in the push rod-nozzle direction and in an activation direction which is perpendicular to the push rod-nozzle direction. An independent claim is also included for a fluid spray device comprising a fluid circulation unit.</p> |
