PUMP CONTROL METHOD AND POPPET VALVE THEREFOR |
| 摘要 |
Displacement control of a multi-piston fluid pump (30) is achieved by real time control of electrically selectable inlet poppet valves (36) in one or more of the cylinders (34). Microprocessor (40) control permits desired variable output characteristics to be matched. An electrically actuable poppet valve using an annular permanent magnet to latch to a solenoid is described. |
