<p>The present invention relates to an automatic pressure control regulator for a reciprocatable double acting booster having a main control valve and a pressure control valve. The main control valve includes: a first valve body having two connecting ports which connect to a first input-output port and a second input-output port; a second valve body integrated with the first valve body having two connecting ports which connect to a first exhaust back pressure port and a second exhaust back pressure; a first spool operating inside the first valve body; and a second spool integrated with the first spool and operating inside the second valve body. The pressure control valve includes: a pressure control valve body having a first side port which connects to a driving port of the first valve body, and having a second side port which connects to a driving device to supply the predetermined pressure, while the back pressure ports connected to the second side port and generating a back pressure; a pressure control valve spool operating inside the pressure control valve body; and a pressing tool for pressure control applying the set pressure on the pressure control valve spool. According to the composition of the automatic pressure control regulator for a reciprocatable double acting booster, the present invention facilitates the assembling construction and installation of the reciprocatable double acting booster by simplifying the control configuration and control flow path while boosted pressure is constantly maintained by being continuously supplied with fluids regardless of the external load changes.</p> |
