  • Component mixing jet
    Patent number: 10888827
    Abstract: A component mixing jet including a jet nozzle housing with at least one component inlet and one component outlet. An axially movable jet needle is arranged in a reception in the jet nozzle housing and can rest against the jet nozzle housing with an axial end in the region of the component outlet in a sealable manner. The jet needle is connected with a membrane fixed in the jet nozzle housing. A pressure chamber is arranged in the jet nozzle housing at the side of the membrane averted from the axial end of the jet needle. The membrane is a holding element for the jet needle and guides the jet needle axially and holds it radially in the reception. The axial region between the membrane and the axial end of the jet needle is free from any bearing element for the jet needle in the region of the component outlet.
