SECTIONAL HYDRAULIC DISTRIBUTOR WITH MECHANICAL MANUAL CONTROL AND WORKING SECTION OF SECTIONAL HYDRAULIC DISTRIBUTOR WITH MECHANICAL MANUAL CONTROL

摘要

FIELD: hydraulic distributor is assigned for systems of remote hydraulic control over executive members-hydraulic drives of cranes, loaders and other mobile building and road machines where it is necessary to ensure stable speeds of movement of working members practically not depending from changing of external loading. ^ SUBSTANCE: in hydraulic distributor pressure and discharging sections are fulfilled in the shape of combined input block of module execution with function of preventive-overflowing valve and with possibility of rigid connection to working sections. At that working section of hydraulic distributor is fulfilled along symmetrically oriented scheme of control and location of main component elements. ^ EFFECT: increases reliability, technical-economic and operational properties. ^ 6 dwg
