Abstract
PURPOSE: To facilitate multi-positioning without using a complex servo mechanism but with the aid of simple device for hydraulic cylinder.
CONSTITUTION: This cylinder unit is provided with air inlets and outlets A through C for passage of high-pressure air, with an airport D admitting and releasing low- pressure air. Supplying or discharging air through airports A through C with low pressure air supplied to the airport D can change the position of poston rod 9 in 8 different ways, depending on relations between pistons 2, 7 and rods 3, 6, 8. In this instance, if the weight is laid on strokes of chambers E through G at the ratio of 4:2:1 for example, all cylinder stroke come to function in 7 different ways. Furthermore, the above system may be expanded and, assuming cylinder pistons number n pieces, a cylinder unit capable of multiple positioning in 25 ways is obtainable
