Claims (1)

Двухпоточный гидравлический привод одноковшового экскаватора, включающий два насоса, связанных с направленными навстречу друг другу проточными каналами многозолотникового гидроаппарата, включающего гидрораспределители, содержащие перемычки в корпусе многозолотникового гидроаппарата, и золотники управления с кромками, обратные и предохранительно-подпиточные клапаны, напорные и сливные гидролинии, отличающийся тем, что золотники управления гидрораспределителей перемещения ковша, рукояти и стрелы, или любой отдельно взятый, например золотник управления гидрораспределителя перемещения стрелы, выполнены с увеличенными проточками на длину хода золотника в одну сторону, при этом общая длина проточки отвечает следующей зависимости:Double-flow hydraulic drive of a single-bucket excavator, including two pumps connected to flowing channels of a multi-head hydraulic unit directed towards each other, including hydraulic distributors containing jumpers in the body of a multi-head hydraulic unit, and control spools with edges, check and safety-make-up valves, pressure and drain hydraulic lines, different the fact that the control spools of the hydraulic control valves for moving the bucket, handle and boom, or any one, for example p spool control valve controls the boom, formed with enlarged recesses on the stroke length of the slide in one direction, the total length of the groove corresponds to the following relationship: L=Н+2S+b,L = H + 2S + b, где Н - величина хода золотника управления в одну сторону;where H is the magnitude of the stroke of the control valve in one direction; 2S - суммарная длина проходных окон проточного канала;2S is the total length of the passage windows of the flow channel; b - длина перемычки корпуса.b is the length of the body jumper.
