Product dispensing system

摘要

A flow control device is disclosed. The flow control device includes a solenoid, the solenoid including an armature. Also, a piston connected to the armature. The piston includes a primary orifice. The piston having an open position and a closed position. A piston spring connected to the piston is also includes and at least one secondary orifice. The movement of the piston to the open position at least partially opens the at least one secondary orifice and the movement of the piston to the closed position at least partially closes the at least one secondary orifice. The movement of the armature actuates the piston movement and controls fluid flow from the primary orifice through the at least one secondary orifice.

1. A product dispensing system for dispensing a first ingredient and a second ingredient comprising:
a flow control device, the flow control device for regulating the dispensing of the first ingredient by the product dispensing system, the flow control device comprising:
a solenoid, the solenoid comprising an armature;a piston connected to the armature, the piston comprising a primary orifice, whereby the piston having an open position and a closed position;a piston spring connected to the piston;at least one secondary orifice wherein movement of the piston to the open position at least partially opens the at least one secondary orifice and wherein movement of the piston to the closed position at least partially closes the at least one secondary orifice; anda flow sensor located downstream from the second orifice;a binary valve comprising:
a plunger;a spring for biasing the plunger in an open position; anda diaphragm actuated by the plunger,wherein the piston actuates the plunger to move the plunger to a closed position; and a pump module configured to be coupled to a supply of a second ingredient,
wherein movement of the armature actuates the piston movement and controls fluid flow from the primary orifice through the at least one secondary orifice, andwherein the flow sensor configured to provide a feedback signal based upon a volume of the first ingredient flowing within the flow control device.
