Summary: Introduction of hydroponic installations is a prospective direction of agriculture, while they allow to get all-the-year-round fresh vegetables, fruits and greenery, including their exotic kinds for some regions. For provision of high efficiency of this equipment (minimal expenses of energy, materials and time, maximal productivity of the plants) there is important to supply the plants with optimal quantity of nutrients (nitrogen, potassium, sulfur, calcium, magnesium, phosphorus, natrium), microelements (iron, boron, iodine, copper, zinc, cobalt, molybdenum, manganese), acids, salts. Herewith concentration of some from these additives can amount several milligrammes. So, an actual task is an accurate batching of the components of nutrients. There are several variants of an equipment for the accurate batching of liquid solutions: valves with electric control for feeding of fuel in jet engines (they have high price because of utilization of expensive materials in their construction), hydraulic engines with periodic turns of executive element for angle less than 360o (don’t provide exact regulation of turning angle) and linear electric-hydraulic engines (have other designation and design that demands of improvement). Authors propose a scheme of improved apparatus for accurate batching of the components of nutrients hydroponic installations, created at the base of the linear electric-hydraulic engine. The apparatus has a simple and reliable design and provides a possibility of high accurate batching of the components of nutrients. There are cited equations and formulas for definition of main working parameters of the apparatus, that can be used for creation of its method of design calculation.
