The high-pressure electro-pneumatic servo valve (HESV) is a core element of the high-pressure pneumatic servo system. The annular clearance and the rounded corner of the spool-sleeve can cause the leakage at null position, thereby affecting high-prec

In this paper, a novel single-stage high-pressure electro-pneumatic servo valve (HESV) directly driven by a voice coil motor (VCM) is proposed for a precision control system. The HESV is a three-position three-way spool-type flow valve. As the fricti

Air pressure control methods consist of constant volume control method and variable volume control method. The constant volume control method under a lower vacuum circumstance has problems with a low pumping capacity of vacuum pump, intensified leaka

The spool of the high-pressure electro-pneumatic servo valve (HESV) is subjected to transient and steady gas flow force during operation, and there is unknown disturbance in the valve spool position control. In order to improve the position control a

A novel voice coil motor (VCM) direct drive single stage high-pressure pneumatic servo valve is designed, and then the steady gas flow force acting on the spool of the servo valve is investigated by numerical simulation and experimental methods in th
