Patent number: 8333307Abstract: A liquid dispensing module includes a dispenser body assembly, a flexible seal, a needle, and an actuator. The dispenser body assembly includes a liquid inlet, a discharge outlet, and a flow channel including a valve seat between the inlet and outlet. The flexible seal engages the dispenser body assembly and includes a downstream end. The needle includes an enlarged portion engaging and retaining the downstream end of the flexible seal to place the flexible seal in lengthwise compression between the enlarged portion and the dispenser body assembly. The needle also includes a valve element that moves between open and closed positions. The flexible seal prevents liquid from leaking out of the flow channel.Type: GrantFiled: October 6, 2009Date of Patent: December 18, 2012Assignee: Nordson CorporationInventors: Christopher R. Chastine, Brett A. Pearson, John M. Riney

Publication number: 20120312838Abstract: In one aspect, an adhesive dispensing system 30 includes a dispensing module 32 having an inlet and an outlet, a supply 35 of hot melt adhesive maintained at low pressure, and a low pressure liquid passageway 44 communicating between the supply 35 and the inlet of the dispensing module 32. Liquid material is received through the inlet at a low pressure, and the dispensing module 32 rapidly develops high pressure at the outlet 78 to jet the liquid material from the outlet 78. In another aspect, an apparatus for jetting liquid material includes a dispenser body 38 having a liquid chamber 40. A piston 54 is movably disposed within the liquid chamber 40, from a position wherein a piston tip 58 is spaced from a complimentary shaped recess 76, to a position wherein the piston tip 58 effectively seals off the recess 76, then to a position wherein the piston tip 58 is received within the recess 76 to displace a discrete volume of liquid material from the recess 76.Type: ApplicationFiled: January 7, 2011Publication date: December 13, 2012Applicant: Nordson CorporationInventors: Justin A.

Publication number: 20120248155Abstract: A system for dispensing liquid material with different configurations of air assisted fiberization or filament movement (e.g., meltblowing, controlled fiberization). In particular, front access for mounting a selected nozzle only requires adjustment of one lever and one fastener. Features of the lever and nozzle allow assisted ejection of the nozzle, even when the nozzle has become adhered to a die body through use. In addition, a nozzle mounting surface of the die body provides a universal interface to the various types of nozzles. An air cavity in the die body and air troughs in selected types of nozzles balance and adjust air flow.Type: ApplicationFiled: June 12, 2012Publication date: October 4, 2012Applicant: NORDSON CORPORATIONInventors: Charles A. Gressett, JR., David E. Hardy, John M. Riney, Laurence B. Saidman, Paul Schmidt

Patent number: 8201716Abstract: Dispensers with replaceable actuators and related methods. A representative dispenser includes a sealed fluid chamber with a fluid inlet and a valve seat, a valve member configured to be reciprocally moveable relative to the valve seat, and an actuator interface. The dispenser includes first and second actuators configured to be coupled with the actuator interface for reciprocally moving the valve member. The first actuator is configured to operate by a different motive force than the second actuator. The first actuator can be removed and replaced with the second actuator. The methods involve the ability to replace the first actuator with a second actuator.Type: GrantFiled: February 25, 2010Date of Patent: June 19, 2012Assignee: Nordson CorporationInventors: Christopher R.

Patent number: 7617955Abstract: 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.Type: GrantFiled: October 28, 2004Date of Patent: November 17, 2009Assignee: Nordson CorporationInventor: John M.
