Abstract
A valve system for use with a high-speed filling machine, in which a solenoid valve controlled by the main shaft of the filling machine, selectively supplies air under pressure to a respective pneumatically operated piston-cylinder unit which in its turn actuates a pinch clamp valve or a rotary valve to thereby effectively close the discharge or intake of the filling pump; with the use of a pinch clamp valve, its piston clamp assembly closes a hose section connected to the pump of the filling machine during its reciprocatory movement by pinching the same against a clamping bar of the pinch clamp frame structure; two rotary valves or pinch clamp assemblies may be used thereby, one for the intake cycle and one for the discharge cycle of the filling pump, which are then both controlled from the main shaft by the electromagnetically controlled solenoid valve.
