Abstract

PURPOSE:To obtain a clean valve with a simple construction by an arrangement wherein an ink inlet and outlet are provided on the peripheral portion of a cylindrical valve tube, while a valve seat for an ink exhaust port is provided at one end thereof, and a spool-shaped sliding rod is housed in the valve tube. CONSTITUTION:A spool-shaped sliding rod 10 is slidably housed in a cylindrical valve tube 1 which is provided on its peripheral portion with an ink inlet 2 and outlet 3 and is also provided at one end thereof with an ink exhaust port 4 and a valve seat 5 therefor. The sliding rod 10 has two O-rings 11, 12 fitted in its peripheral portions and includes a rubber member 13 at its end portion opposite to the valve seat 5, and then it is driven reciprocally by means of a push type solenoid coil 20 and a tension type return spring 21. As a result, the valve can be constructed into a simple unitized structure and it becomes possible to obtain a clean valve unnecessitating the use of a corrosive magnetic plunger.
