| Abstract | A new kind of roller thrust-torsion coupling was designed in this paper, with low friction and simple structure, linear movement of proportional solenoid can be changed into rotation of the spool movement, at the same time, proportional solenoid's thrust is amplified. With large flow and simple structure, 2D Electro-hydraulic Proportional Directional Valve (EPDV) which is position feedback mainly consists of roller thrust-torsion coupling and proportional solenoid. Based on the principle of roller thrust-torsion coupling, 2D EPDV had been studied through its mathematical model which was simulated with software MATLAB. Direct-acting and pilot-operated experiment results show: with good input and output characteristics, high pressure and large flow control can be achieved by this valve, no-load hysteresis is 1%, flow hysteresis is under 5% when system pressure is at 21 MPa, its linearity and repeating characteristic are all good. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
