FLUID DISPENSERS FOR FLUID PRODUCTS AND DISPENSING SOLUTIONS
摘要:
A fluid dispenser (10) includes a housing (12) and a valving rod (14). The housing includes an inlet (28) that receives a fluid product, an internal chamber (26) in fluid communication with the inlet, a discharge port (20) in fluid communication with the internal chamber that dispenses fluid from the internal chamber, a dispensing fluid inlet (38) that receives a dispensing fluid, and a dispensing fluid passage system that carries the dispensing fluid to the discharge port. The valving rod is disposed in the housing and moves within the internal chamber between an open position and a closed position. The dispensing fluid passage system includes a first passageway (44) that carries the dispensing fluid in a first direction and a second passageway (48) that carries the dispensing fluid in a second direction. The second passageway has a distal end that dispenses the dispensing fluid proximate the discharge port.
