Abstract
A component feed nozzle includes a housing, which has a component inlet and a component outlet, a piston-shaped closing body, which is slidably supported in the housing and which can be moved back and forth axially. The component outlet is closed by the front end of the closing body in a first position and the component outlet is released or opened in a second position. The component feed nozzle has a membrane seal, which is fastened to the rear end of the closing body and to the housing in such a way that the closing body is completely on one face of the membrane seal. The housing and/or the closing body are designed in such a way that the component reaches all surfaces of the closing body and thus the component pressure is applied to the complete effective surface of the membrane.
