Angular thermostatic device for regulating heating valves has actuator with rotary element with cross-sectional expansion that exerts linear effect on control device when rotary element turns

摘要

The angular thermostatic device has a control device (2,4,6) that acts on the valve and is self-regulating depending on the external temp. and an actuator for setting the demand value for the control device. The actuator has a rotary element (14) with a cross-sectional increase (16) that exerts a linear effect on the control device when the rotary element turns.
