<p>In a mixing apparatus for spraying-out of a liquid mixture consisting of at least two liquids, each from a respective reservoir (I, II), the apparatus having a number of liquid pumps (1,2) corresponding to the number of liquids, said liquid pumps delivering into a common spraying-out conduit (3) and each being driven of a respective hydraulic motor (4,5), the main novel features are a) that the mixing apparatus comprises a drive assembly (16) directly operationally connected to a first hydraulic pump (6), controlled in a pressure-regulating manner in dependence on the liquid flow at the outflow side of the apparatus, b) that the first hydraulic pump (6) is associated with a first hydraulic motor (4), c) that the first hydraulic motor (4) is operationally connected to both a first liquid pump (1) and to a mechanical gear (7), and d) that the mechanical gear (7) is directly operationally connected to at least one second hydraulic pump (8) driving at least one second hydraulic motor (5) for at least one second liquid pump (2), said second pump (8) having a variable working capacity and hence being controllable. <IMAGE></p> |
