<p>PURPOSE:To improve operatability of a single rod cylinder driving device by selectively outputting, as a target signal, a signal, corresponding to ether one of pressures set by the first and the second setting means according to the driving direction of the single rod cylinder. CONSTITUTION:The first setting means for setting pressure PR at the rod side of a single rod cylinder 1, the second setting means for setting pressure PH at the head side of said cylinder and a judging means for judging a driving direction of the single rod cylinder are provided in a control means 8, and a signal corresponding to ether one of pressures set by the first and the second setting means according to the driving direction of the single rod cylinder 1 is output as a target signal. Difference of cylinder thrust at the time of pressurizing the head from the thrust at the time of pressurizing the rod can thereby be restrained smaller so that operatability can be improved.</p> |
