Abstract
A dispensing valve is provided for dispensing liquid from a cartridge. The valve includes a valve body that is adapted to receive at least a portion of the cartridge therein. A valve member is disposed in the valve body and is adapted for fluid communication with the cartridge. A valve seat element is disposed in the valve body and includes a liquid chamber that is in communication with the liquid outlet and is mounted for reciprocating movement between a closed position engaged with the valve member to prevent liquid from exiting the liquid outlet and an open position disengaged from the valve member to allow liquid to flow from the liquid chamber through the liquid outlet. The valve body may include a longitudinal axis and a receive bore extending along the longitudinal axis, with the liquid outlet being substantially co-axial with the receiving bore.
