Design method for fluid transfer device Abstract The invention relates to a design method for the device using reciprocal movement of the piston to transfer fluid. The method includes providing a body, a switching unit, a triggering unit, a piston unit and a transmission unit; communicating the ends of the first and 5 second passages with the manifold chamber, always communicating the first passage with the receiving chamber, matting the second passage configured with the triggering unit with the help of the triggering end, and arranging for the reset component to alternatively communicate with the input passage or the output passage; 10 arranging for the piston to reciprocally move in the receiving chamber, arranging for the first and second belt wheels to interact with each other through the engagement bewteen the first and second gears, the device has functions of pumping water or compressing air or extracting air, it depends on the kinds of the working medium. 403 301 301 103 201d 404 02b 402 A /mn/ / i A. 6 |
