<p>By designing a regulator unit according to the invention as a combined thermostatically controlled and pressure controlled unit there is achieved the advantage of both regulation forms, which will, however, continue to operate independently of each other. This is achieved by means of a common valve seat having each its valve seat (9, 22) cooperating with two independent valve bodies (7, 23) on each its spindle part (6, 30). The result is an optimisation of the common - but independent - regulation capacity such that when the regulator is in operation it will function as a regular thermostatic control and the opening/closing function of the regulator as a regular pressure control. <IMAGE></p> |
