ELECTRIC PNEUMATIC CONVERTER AND ELECTRIC PNEUMATIC SWITCH VALVE Russian patent published in 2019 - IPC F15C3/14 F15B13/44 

FIELD: instrument engineering.

SUBSTANCE: converter for connection with fluid source under pressure contains mechanism for installation of pneumatic output signal by means of electric input signal. Converter provides assembly of the lower casing and assembly of the upper casing. Lower casing assembly comprises lower casing configured to connect inlet branch pipe. Inlet pipe is in hydraulic connection with inlet hole and is periodically in hydraulic communication with output hole of lower jacket through internal fluid bypass channel. Lower casing additionally contains an exhaust pipe, which is in hydraulic communication with the exhaust hole, and is periodically in hydraulic communication with the output hole of the lower casing through the internal fluid bypass channel. Upper casing assemble comprises the upper casing to attach the coil and the armature so that the upper casing, the coil and the armature determine the closing electromagnetic circuit, which provides for periodic contact of the anchor with the inlet branch pipe and the exhaust branch pipe of the lower casing assembly.

EFFECT: technical result is simplified design.
