ELECTRICALLY-CONTROLLED METERING VALVE

摘要

FIELD: engines and pumps. ^ SUBSTANCE: invention relates to pipeline valves and accessories and is designed to control the higher-pressure working medium feed in liquid- and air-operated systems. The electrically-controlled metering valve has a body with inlet and outlet channels. The body accommodates a spring-loaded electrically-driven plunger. The said plunger drive is made up of two spaced apart electrical coils connected via a control unit to a current pulse generator. A moving plate magnetically-coupled with the said coils is arranged between them and connected to one end of the aforesaid plunger. The other end of the latter accommodates the inlet channel shut-off element. The plate is made from a non-magnetic material with a specific ohmic resistance allowing generation of eddy currents in the said plate on feeding current pulses to any aforesaid coil. ^ EFFECT: valve faster response to control signals, higher reliability and expanded performances. ^ 3 cl, 1 dwg
