Abstract
PURPOSE: To constitute a servo valve to control flow rate or pressure with precisely and at high speed with less leak even under extended high pressure to be more than 500 atmospheric pressure, sufficient durability and reliability.
CONSTITUTION: Supply of low pressure oil is controlled by a pilot valve 12, while supply of high pressure oil is controlled by a main valve 32. Two pieces of high hydraulic control ports C1, C2 are installed on a main valve 32. Each port is constituted by poppet valves 52, 54 and the valve body of each poppet valve is elastically connected through an elastic part mechanism 56. Opening degree of each poppet valve 52, 54 is adjusted by oil pressure supplied through the pilot valve 12, even in case of fluid under super-high pressure, it gives less leak and the pressure or flow rate is correctly controlled.
