FIELD: agriculture. SUBSTANCE: cow milking manipulator has milk claw with opening positioned in upper part of milk receiving chamber. Section area of opening is equal to section area of discharge branch pipe of milk claw. Pneumatic chamber with long working stroke is positioned above opening. Manipulator is formed as corrugation working in compression. Movable bottom of corrugation makes opening valve for introduction of air into milk claw. Float chamber of milk flow rate sensor is made in the form of milk pipe with restrictors for restricting movement of magnetic float provided with guides positioned at an angle to milk flow. Pneumatic signal former of milk flow rate sensor is made of jet type, with double-armed divider made from ferromagnetic material. Pneumatic signal former is positioned in parallel with milk pipe. Pneumatic members of manipulator control device are positioned in hermetically sealed housing communicated with atmosphere through filter. Communication of control device with milking unit and actuating devices is effectuated through connector with unions. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 4 cl, 3 dwg
