Abstract
An adjustable pressure valve has a valve body, an inactive cap and an active cap. The inactive cap is mounted in the outlet of the valve body, abuts against the piston in the valve body and has an inclined edge. The active cap is mounted rotatably against the inactive cap and has an inclined edge abutting against the inclined edge of the inactive cap. When the active cap is rotated relative to the inactive cap, the inactive cap is pushed by the inclined edge of the active cap to slide inwardly or outwardly. Then the elastic element in the valve body is compressed more or less by the slide of the active cap to adjust the preset outlet pressure without disassembling the adjustable pressure valve.
