Rapid Decompression Regulator

Figs. 1 and 2 show a regulator which decompresses a compressed system, such as an ink jet printing system, at a very high speed without overshooting ambient pressure.

The rapid decompression regulator comprises a cylinder or tank 10 in which a ball 12 is placed. The cylinder is fitted with ingressed and egressed pipes 14 and 16, respectively. In operation, the compressed system (not shown) is coupled to one of the pipes. For description purposes, assume that the system is coupled to pipe 14. With the ball at the bottom of the cylinder, fluid motion around the ball is restricted. As the volume of fluid increases in pipe 14, the ball is forced to rise from the bottom to the top of the cylinder. As the ball reaches the top, it is stopped by the top of the cylinder or adjustable screw 18. At this point, the ball acts as a restricter to the movement of fluid in the cylinder. After ambient pressure is reached, the ball is forced by gravity to return to its original position. The showing in Fig. 1 represents a fixed version, whereas Fig. 2 represents an adjustable version wherein screw 18 is used for adjusting the level to which the ball may rise.
