Abstract

PURPOSE:To provide a steady, high-reliable, and compact tilted valve which performs a rapid opening and closing operation, by a method wherein two valve chambers are formed with 3 O rings between a pipe, having a plural number of pores piercing through its pipe wall, and a cylinder whose diameter is slightly larger than that of the pipe. CONSTITUTION:O rings 16a, 16b, 16c are placed at given intervals in a cylinder 15 whose diameter is slightly larger than an outer diameter of a pipe 11 to form valve chambers 22a and 22b. In case a coil 20 is not energized, the pipe 11 is pushed rightward through the spring force of a spring 21, and pores 13 are located in a position of the valve chamber 22b to shut down ink paths 12 and 17. With the coil 20 energized, a plunger 19 moves to bring the pores 13 into the position of the valve chamber 22a, and ink in the ink path 17 passes through the pores 13 via the valve chamber 22a to flow to the ink path 12.
