Abstract

A component-feed nozzle for a reaction-mixing head of a reaction injection device includes a housing having a component inlet and a component outlet. Received in the housing is a closing and flow restriction member which is movable by a linear drive between at least two positions. In a first position, the closing and flow restriction member closes the component outlet, and in a second position clears the component outlet, thereby establishing a flow communication between the component inlet and the component outlet. The closing and flow restriction member has at least a first area and a second area, which generate forces in opposite directions, when the component pressure is applied, wherein the areas are sized in such a way that the opposing forces substantially offset one another.
