TWO COMPONENT FOAM DISPENSING APPARATUS
First Claim
1. A foam dispensing apparatus for dispensing a mixture of a first fluid and a second fluid, said apparatus comprising:
- a dispensing head for mixing the first fluid and the second fluid and dispensing the mixture onto a substrate;
a handle extending from said dispensing head for a user to grasp and manipulate to operate said dispensing head; and
a manifold assembly mounted to said dispensing head, said manifold assembly comprising;
a purge portion defining a gas inlet, a cleansing fluid inlet, an outlet in fluid communication with said dispensing head, and a plurality of passageways interconnecting said gas inlet, said cleansing fluid inlet and said outlet for supplying a gas and a cleansing fluid to said dispensing head;
a first supply portion mounted to said purge portion and defining a first material inlet for receiving the first fluid, a first material outlet coupled to said dispensing head for supplying said dispensing head with the first fluid and a first fluid passageway interconnecting said first material inlet and said first material outlet; and
a second supply portion mounted to said purge portion and defining a second material inlet for receiving the second fluid, a second material outlet coupled to said dispensing head for supplying said dispensing head with the second fluid and a second fluid passageway interconnecting said second material inlet and said second material outlet.

Abstract
A foam dispensing assembly comprises a dispensing head and a manifold assembly. The manifold assembly includes a purge portion for supplying a gas and a cleansing fluid to the dispensing head, a first supply portion for supplying a first fluid to the dispensing head and a second supply portion for supplying a second fluid to the dispensing head. Each of the purge portion, the first supply portion and the second supply portion include a plurality of check valves and flow control valves for controlling the flow of the first fluid, the second fluid, the gas and the cleansing fluid through the manifold assembly. Each of the first supply portion and the second supply portion include an integral flow control device for regulating a fluid flow rate to the dispensing head, and a thermometer for sensing the temperature of the first fluid and the second fluid respectively.
