ABSTRACT:
A dispensing module for dispensing liquid includes a dispensing body having an inlet, a discharge outlet, and a flow channel therebetween having a valve seat. A needle having a valve element is mounted to the body and reciprocates therein between an open position, in which the valve element is disengaged from the valve seat thereby allowing liquid flow, and a closed position, in which the valve element is engaged with the valve seat thereby preventing liquid flow. A needle guide is mounted to the dispenser body and includes a passage for receiving a portion of the needle. A flexible seal includes a first end coupled to the needle guide and a second end coupled to the needle and moving therewith. An actuator is operatively coupled to the needle and moves the needle between the open and closed positions. The seal includes a central portion with an interior cavity that stretches and compresses as the needle reciprocates.
