Pneumatic linear drive position measurement device for tools, industrial machines has two opposing valves mounted so as to be displaceable in drive direction, held in position by fluidic cylinders

摘要

The device has two opposing valves mounted so as to be displaceable in the drive direction and held in position by fluidic cylinders. The movable construction (9) is movably mounted on a shaft (8) and two toothed rods or other suitable materials are used to achieve a force-locking state for positioning. A compressed air cylinder and the valves have a common air supply via an additional 3/2-way valve (16).
