Electrical actuator control

摘要

An electrical actuator control is used with an electrical actuator mechanism (7) for controlling the flow of fluid through a valve in a central heating system. The control incorporates a thermoelectric generator (1) to be arranged in heat transmissive relationship with the fluid, the flow of which is to be controlled by the valve or the like, flowing into a radiator of the central heating system, the thermoelectric generator providing a relatively constant low level of power. The power generated by the thermoelectric means (1) is stored in rechargeable electrical storage means (3) for intermittent operation of the electrical actuator mechanism (7). <IMAGE>
