Purpose of the development: Multi-Mode is designed for hydraulic distributor of mobile machinery in order to ensure discharge of hydraulic pump, hydraulic flow control, maximum flow of hydraulic, hydraulic drive overload protection.

Recommended application field: Hydraulic system, hydraulic machine.

Technical characteristic: Orifice in. 20. Nominal flow rate (l / min): 20 ... 100. Nominal pressure MPa 20. The maximum pressure, MPa 25. Differential pressure at the "pump-drain", MPa: 0,2 ... 0,3. Differential pressure at the "pump-consumer", MPa: 0,7 ... 0,8. Maximum number of sections, pcs. 20: 6. weight: working section - 3.6 kg; slam-overflow section - 2.3 kg; cover - 0.7 kg.

The development stage readiness: Pre-production model is made

Technical and economic effect: Multimode control valve provides a reduction in energy loss, and improved static and dynamic characteristics of the hydraulic drive by combining advantages of domestic and foreign hydraulic circuits sensitive to load.

Description of the development:
()
Distributor and has a sectional structure composed of sections slam - overflow , one or more working sections and lid. Slam- overflow section consists of relief and overflow valves. Due to the excess flow valve provides load-independent flow control . Working section consists of a distribution valve which can be set in the positions "up" , "neutral " and " lowering" . For sealing cavities connected hydraulic motors installed in the test section bilateral quick fit . Distributor can be used in control systems based on hydraulic drives as unregulated and regulated hydraulic pump . In the former case, a steady circulation of the working fluid with a static accuracy of less than 11% and limiting peak pressure pump no more than 15 %. In the hydraulic circuit on the basis of controlled hydraulic pump provides the ability to connect a control line from the control valve to the hydraulic pump flow controller .
