Title of the invention: 5-port electro-pneumatic proportional valve The scope of the utility model registration claims and the brief description of the drawings are amended as follows. [Claims for Utility Model Registration] A spool driven by a proportional solenoid is provided within the valve body having a supply port, a pair of output ports, and a pair of discharge ports, and within the stroke range of the spool, the above-mentioned A proportional valve function part that proportionally controls the output pressure to one output port by balancing the driving force of the proportional solenoid and the feedback force acting on the spool, and a switching valve function part that switches the other output port to the supply port. In the 5-port electro-pneumatic proportional valve, the stroke range of the proportional solenoid, which provides a substantially constant suction force proportional to the amount of energization regardless of the stroke, is assigned to drive the spool in the proportional valve function part, A 5-port electro-pneumatic proportional valve characterized in that a stroke range including a range in which the suction force corresponding to a constant amount of energization fluctuates depending on the stroke is assigned to drive a spool in a switching valve function part. [Brief Description of the Drawings] Fig. 1 is a longitudinal sectional front view of the main parts of the embodiment of the present invention, Fig. 2 A to C are explanatory diagrams of operation, Fig. 3 is an explanatory diagram of the stroke of the proportional solenoid, and Fig. 4 is a proportional solenoid diagram. FIG. 3 is a diagram showing the attraction force characteristics of a solenoid. P... Supply port, A, B... Output port, E
