【Abstract】 Digital high--speed on--off valve was used as pilot valve to compose a digital electro--hydraulic proportional multi--way directional valve in order to realize digital control of loader attachment. Math model and control regularity of the digital electro--hydraulic proportional multi--way directional valve are presented in the article. Computer simulation and experimental verification have been carried out.更多还原
