Abstract

PURPOSE:To automatically control the change in pressure and to remarkably improve the working efficiency, by incorporately containing a plurality of sets of solenoid valves directly coupled with pressure reducing valves and switching the fluid pressure with pressure reducing valves and switching the fluid pressure in a plurality of steps with selective switching of each solenoid valve. CONSTITUTION:Reducing valves a1-a4 and solenoid valves b1-b4 are connected in series in a variable pressure device 1 and they are contained in a case incorporatedly. The secondary set pressure of the reducing valves a1-a4 is respectively different and the adjustment of pressure is made with an external adjusting screw. When compressed air is applied to an input tube of the device 1 from an air compressor and only the valve b1 is opened with a solenoid valve 10 opened, the air with the set pressure is applied to an air cylinder 11 through a flow rate control valve 12 for the operation in accordance with the air pressure. This is the same for the other valves b2-b4. Thus, the changeover of air pressure can be controlled electrically through the use of the valves b1-b4 automatically.

For example, when controlling the drive Iy with medium oil pressure, for example, when controlling the piston rod of an air cylinder by dividing it into stages MF and MF of speed, /') 0 pressure reducing valve is used to control the supply of air to the air cylinder. The pressure is adjusted by switching the pressure to the next step. Currently, the pressure control system relies on manual IFK. Therefore, the work that requires frequent pressure T/&(
