FIELD: engines and pumps.SUBSTANCE: invention relates to flow rate regulation with the help of linear pump. Invention disclosed distribution unit with variable and constant ratio of dispensed components. DC motor drives the gear pump submerged into fluid feed unit. Output of the latter feeds the hydraulic linear motor, its operating direction being controlled by two outlet reversing valves. Fluid lines motor drives one or two fluid transfer pumps secured to fluid pump. Pump outlet pressure and/or flow rate adjustment for fluid transfer is carried out by varying the DC motor output torque with the help of engine control unit made to order. Engine control engine exploits measurements of linear position transducer and pressure transducer arranged at fluid transfer pump outlet as the main adjustable process parameters (or feedback between transducers and control device) for pump regulation.EFFECT: lower costs.4 cl, 2 dwg |
