Abstract

A tamper-resistant pressure regulator (10) is provided in which a cover (24) is mechanically coupled to an Actuator adjustment assembly (14) whereby removal of the cover causes a change in the regulator pressing setting. The actuator adjustment assembly (14) includes disk (26), a spring (28) and a spring plate (30). The regulator pressure is set by adjusting the amount of compression of the spring (28), in particular by changing the axial position of the actuator disk (26) and spring plate (30) by inserting a tool on the tool interface (36) through the hole cap (38). Since the cover (24) and the actuator disk (26) are coupled by threads (32, 34), the cover cannot be repositioned without to change the setting pressure, thus allowing such change or tampering to be detected after the fact.
