    摘要： A mixing and dispensing head is designed for use in a two component foam system. The head includes a body having a mixing chamber formed therein along a longitudinal axis and having a dispensing channel downstream of the mixing chamber. At least two supply portions are connected to the body, with each of the supply portions for supplying one of the components to the mixing chamber at a component entry location. Each of the component entry locations is longitudinally offset from each other. A rotating mixing member within the mixing chamber for mixing the components together to form the foam product. The mixing member includes a cylindrical core having indentations in the core and having angled vanes extending from the core. A shutoff portion is provided for stopping the flow of product from the dispensing channel.
