A spacer type pressure reducing valve for adjusting a fluid pressure is mounted between a solenoid valve,Reducing Valves which switches a flowing direction of pressurized fluid, and a base, which supplies pressurized fluid to the solenoid valve. First and second pressure-reducing portions are integrally accommodated in a valve body of the spacer type pressure reducing valve. The spacer type pressure reducing valve is compact and is capable of adjusting pressure in two output ports. Balance Valves A spacer type pressure reducing valve which adjusts an output fluid pressure and which is disposed between a switching valve having one supply communication hole, two output communication holes and a discharge communication hole and a base having a plurality of communication holes corresponding to the above communication holes, wherein this spacer type pressure reducing valve comprises a valve body sandwiched between the switching valve and the base; BALL VALVEStwo pressure-adjusting valve holes formed in the valve body in parallel to each other, and two pressure-adjusting valve rods movably accommodated in the pressure-adjusting valve holes; one supply communication passage for connecting supply communication holes in the valve body corresponding to the switching valve and the base, and two output communication passages for connecting the corresponding output communication holes, and two discharge communication passages for connecting corresponding discharge communication holes; a pressure-adjusting valve seat and a pressure-adjusting valve body formed in one of the pressure-adjusting valve holes and a pressure-adjusting valve rod therein for adjusting the fluid pressure output from one of the output communication passages, and another pressure-adjusting valve seat and another pressure-adjusting valve body formed in the other pressure-adjusting valve hole and a pressure-adjusting valve rod therein for adjusting fluid pressure output from the other output communication passage; pressure-adjusting chambers respectively provided on one ends of the two pressure-adjusting valve rods, and returning chambers respectively provided on the other ends of the pressure-adjusting valve rods; pressure-adjusting pistons slidably provided in the pressure-adjusting chambers; pressure-adjusting springs for biasing the pressure-adjusting pistons toward the pressure-adjusting valve rods; returning springs respectively provided in the returning chambers for biasing the pressure-adjusting valve rods toward the pressure-adjusting pistons; a communication flow-passage for connecting the pressure-adjusting chamber and the returning chamber on the opposite ends of the one output communication passage and the one pressure-adjusting valve rod, and a communication flow-passage for connecting the pressure-adjusting chamber and the returning chamber on the opposite ends of the other output communication passage and the other pressure-adjusting valve rod.
