Abstract (en)
[origin: EP0067934A2] A device (5) for economizing on compressed air, or other fluids under pressure fed to pneumatic cylinders (1) used for example in the field of machines and machine-tools in general. The device comprises a pressure reducing valve (12), arranged within a first passage (9, 10, 11) for feeding the fluid to the cylinder (1) to be controlled, and a single-acting valve (25) located within a second passage (22) for the return of the fluid from said cylinder (1), which passage coaxially encircles the pressure reducing valve (12), thereby achieving a device with a compact and functional structure.
