Abstract
The invention relates to a metering valve (10, 10 ') for viscous material, comprising: a housing (12); material channels extending in the housing (12) and leading into a plurality of material outlet openings (26); the invention relates to a valve assembly (10) having a housing (12), having a number of valve needles (24) which correspond to the number of material discharge openings (26) and which are movably mounted in the housing (12), a valve seat (22) being associated with each valve needle (24) and each valve needle (24) being movable between a closed position, in which the valve needle is located on the associated valve seat (22) and closes one of the material discharge openings (26), and an open position, in which the valve needle (24) is located on the associated valve seat (22) and closes the other of the material discharge openings (26). An open position in which the associated material discharge opening (26) is open; and a number of actuators (64) for loading the valve needle (24). According to the invention, the number of actuators (64) is smaller than the number of valve needles (24), and at least one of the actuators (64) simultaneously acts on at least two of the valve needles (24).
