Abstract
A station for forming a container from a preform. The station having a main body including a preform seat adapted to receive a preform and an injection assembly. The injection assembly including an injection nozzle, comprising an inlet and an outlet, that is movable between a retracted position and an injection position. An injection device arranged to inject liquid to the inlet of the injection nozzle. The injection device includes a housing, defining a main chamber having an actuation aperture, and a closing element movable relative to the housing and closing the actuation aperture. The injection nozzle and the housing of the injection device are rigidly fixed to each other so as to form a single unit.
Claims13
A station for forming a container from a preform, the station comprising:
- a main body, the main body including a preform seat adapted to receive the preform;
- and
- an injection assembly, the injection assembly including
- an injection nozzle having an inlet and an outlet, the injection nozzle being movable between a retracted position and an injection position relative to the preform seat, the outlet being in fluidic communication with the preform when the injection nozzle is in the injection position, and
- an injection device arranged to inject liquid from a liquid source to the inlet of the injection nozzle, the injection device comprising a housing defining a main chamber having an actuation aperture, and a closing element movable relative to the housing and closing the actuation aperture in a fluid tight manner,
- a valve system, operable by a controller, in a closed state, wherein the fluidic communication between the outlet and the main chamber is interrupted such that the main chamber, the closing element and the valve system in the closed state delimit a closed volume,
- wherein the injection nozzle and the housing of the injection device are rigidly fixed to each other such as to form a single unit movable between the retracted position and the injection position, the station further comprising an actuator fixed relative to the main body and coupled to the closing element to move the closing element with respect to the main body, the controller being configured to place the station in a displacement configuration wherein the valve system is in the closed state and the closed volume is filled with liquid, the closing element being fixed by the closed volume relative to the housing and the injection nozzle and the actuator being coupled by the closing element to the single unit of the housing and the injection nozzle whereby movement between the retracted and injection positions is effectuated by the actuator.
