Abstract: A pressure fluid-driven apparatus includes a zero point position-determining mechanism, including an oil supply-adjusting knob formed with an arrow-shaped recess for indicating a zero point position, an insert member internally fitted into a hole of the oil supply-adjusting knob, a stopper for setting an assembled state of the oil supply-adjusting knob and the insert member to be at a zero point position, and a first spline section and a second spline section fitted to one another to determine the position so that the zero point position of the recess corresponds to that of a holder.

Abstract: The present invention provides a pressure control apparatus for controlling the pressure at an output port without reducing the effective sectional area by controlling a main valve through the switching operation of a small-sized directional control valve, wherein the main valve has any of the following functions, i.e. a function of-providing a valve full-open position, a function of reducing pressure, and a function of providing a valve full-closed position. When a diaphragm chamber is placed at the secondary pressure by switching the directional control valve, the primary pressure is reduced by the main valve, and a predetermined reduced pressure is outputted. When the diaphragm chamber is at the primary pressure, the main valve is fully closed. When the diaphragm chamber is at the atmospheric pressure, the main valve fully opens, and hence the primary-side fluid flows to the output port as it is.

Abstract translation: 本发明提供一种用于通过小型方向控制阀的切换操作控制主阀而不降低有效截面面积来控制输出口处的压力的压力控制装置，其中主阀具有以下任何功能 ，即提供阀门全开位置的功能，降低压力的功能以及提供阀门全闭合位置的功能。 当通过切换方向控制阀将隔膜室置于二次压力时，通过主阀减小一次压力，并输出预定的减压。 当隔膜室处于初级压力时，主阀完全关闭。 当隔膜室处于大气压力时，主阀完全打开，因此初级侧流体原样流入输出口。
