Abstract
Logic fluid programme circuit where a first valve section has a casing with inlet and outlet and a plunger piston and means to load the piston in one direction into a first position where this first valve section is so operated by hand that the piston can be moved into a second position in the opposite direction. a second similarly equipped and operating valve section is operated to move its piston to a second position when a pressurised fluid medium is fed to its piston via the inlet of the second valve section. consequently, there is a connection between the outlets at the rest position of the first valve section and a connection between the outlet and the inlet of the first valve section on operating the first valve section.
