An experimental study on the control of pressure transients using an orifice

Control of pressure transients in a hydraulic system may be important and necessary to avoid failure and to improve the efficiency of operation. This study addresses the design and use of an orifice to provide the desired control to a hydraulic actuator system. Control is accomplished by installing orifices at appropriate locations in the system. Experimental results show that an orifice can be used to obtain control of shock and the control level depends on the orifice size, orifice type, operating pressure and flow rate. From the experimental data, an empirical design chart for controlling pressure rise using an orifice has been derived.
